Recent Longevity News for the seven days ending 7/24/13.  You should consult your doctor if you are taking any medications.

Breastfed Children Are Less Likely to Develop ADHD Later in Life, Study Suggests - Science Daily, 7/22/13 - "researchers compared breastfeeding histories of children from six to 12 years of age at Schneider's Children Medical Center in Israel ... children with ADHD were far less likely to be breastfed in their first year of life than the children in the other groups. At three months, only 43 percent of children in the ADHD group were breastfed compared to 69 percent of the sibling group and 73 percent of the control group. At six months, 29 percent of the ADHD group was breastfed, compared to 50 percent of the sibling group and 57 percent of the control group"

Skipping Breakfast May Increase Coronary Heart Disease Risk - Science Daily, 7/22/12 - "Researchers analyzed food frequency questionnaire data and tracked health outcomes for 16 years (1992-2008) on 26,902 male health professionals ages 45-82. They found: ... Men who reported they skipped breakfast had a 27 percent higher risk of heart attack or death from coronary heart disease than those who reported they didn't ... Men who reported eating late at night (eating after going to bed) had a 55 percent higher coronary heart disease risk than those who didn't. But researchers were less convinced this was a major public health concern because few men in the study reported this behavior"

Vaccinating boys plays key role in HPV prevention - Science Daily, 7/22/13 - "HPV has been linked to anal, penile and certain types of throat cancers in men. Since the virus is also responsible for various cancers in women, vaccinating boys aged 11 to 21 will play a crucial role in reducing cancer rates across the sexes ... HPV is the single most common sexually transmitted infection"

Vitamin D Insufficiency Prevalent in Psychiatric Patients - Medscape, 7/22/13 - "Among the patients, 75% had vitamin D levels lower than 30 ng/mL, generally considered by groups, including the American College of Physicians, to represent insufficiency ... Vitamin D insufficiency may be a causative factor in the pathogenesis of mental illness through interactions that affect cellular mechanisms, which eventually diverge into different clinically observed phenotypes ... as many as 63% of patients with insufficient vitamin D levels were not treated with supplementation ... Physicians who work in those units should make sure vitamin D screening and evaluation is part of routine evaluation of patients, not necessarily because it may be causative of psychiatric symptoms but because there are a lot of conditions that are associated with vitamin D deficiency — osteoporosis, diabetes, and some other medical problems that are also relatively common in patients with psychiatric illnesses" - See vitamin D at Amazon.com.

Topical Agents for Hair Growth Promotion - Medscape, 7/22/13 - "androgenetic alopecia (AGA), i.e., male pattern hair loss and female pattern hair loss ... Melantonin has long been known to modulate hair growth. Animal testing has shown that melatonin stimulates the anagen phase of hair growth.[23] In a double-blind, randomized, placebocontrolled study 40 women with diffuse alopecia (n=28) or AGA (n=12) were treated topically for 6 months with 1 ml daily of 0.1% melatonin-alcohol solution versus vehicle. Trichograms were used to determine efficacy in the frontal and occipital scalp areas. At the end of the study, the AGA group demonstrated a statistically significant increase in anagen hairs in the occiput region compared to placebo (mean 78 to 82 hairs), but no difference was shown with placebo in the frontal area.[24] The group with diffuse alopecia showed a substantial increase in frontal hair. Plasma melatonin levels were elevated under treatment with melatonin, but did not exceed the physiological night peak" - See melatonin at Amazon.com.

Avoiding estrogen therapy led to deaths of nearly 50,000 women, study says | Fox News - Fox News, 7/19/13 - "in a study published in the American Journal of Public Health, researchers are arguing that misconceptions about hormonal treatments also led women to reject estrogen-only treatments, which have numerous health benefits including reduced mortality and lower incidences of breast cancer and heart disease ... researchers estimated that up to 48,835 women died prematurely between 2002 and 2011 because they failed to use estrogen therapy treatments"

Eating Eggs Is Not Linked to High Cholesterol in Adolescents, Study Suggests - Science Daily, 7/19/13 - "the most recent research suggests that increased serum cholesterol is more affected by intake of saturated fats and trans fats -- present in red meat, industrial baked goods, etc. -- than by the amount of cholesterol in the diet ... eating larger amounts of egg is neither linked to higher serum cholesterol nor to worse cardiovascular health in adolescents, regardless of their levels of physical activity ... The conclusions, published in the journal Nutrición Hospitalaria, confirm recent studies in healthy adults that suggest that an intake of up to seven eggs a week is not associated with an increased risk of developing cardiovascular diseases ... a medium-size egg contains 200 milligrams of cholesterol but has more unsaturated fats than saturated fats and only has 70 calories"

Testosterone Produces Mixed Results in Prostate Cancer Study - Medscape, 7/18/13 - "In men with prostate cancer, the use of transdermal testosterone-replacement therapy (TRT) after radical prostatectomy produced an increase in testosterone levels, but also had the undesirable effect of increasing prostate-specific antigen (PSA) levels ... However, the use of TRT did not appear to increase biochemical recurrence rates during follow-up, which was a median of 27.5 months for treated men"

Too Little Vitamin D May Hasten Disability as You Age - WebMD, 7/17/13 - "It's estimated that as many as 90 percent of older people are vitamin D-deficient ... Among participants aged 65 to 88, those with the lowest vitamin D levels were 1.7 times as likely to have at least one physical limitation as those with the highest vitamin D levels. Among participants aged 55 to 65, those with the lowest vitamin D levels were twice as likely to have at least one physical limitation as those with the highest vitamin D levels" - [Abstract] - See vitamin D at Amazon.com.

Vitamins and minerals can boost energy and enhance mood - Science Daily, 7/16/13 - "In a series of studies she recently conducted in Canada, Kaplan found of the 97 adults with diagnosed mood disorders who kept a three-day food record, a higher intake of vitamins and minerals were significantly correlated with overall enhanced mental functioning ... Other vitamins that have been known to enhance mood, said C.J. Geiger, Ph.D., president of Geiger & Associates, LLC, and research associate professor in the division of nutrition at the University of Utah, include 5-Hydroxytryptophan (5 HTP), Vitamins B and D, as well as ginkgo biloba and Omega 3" - See 5-HTP products at Amazon.com and Ginkgo biloba at Amazon.com.

People With Impaired Glucose Tolerance Can Show Cognitive Dysfunction -Science Daily, 7/16/13 - "she examined 31 previous studies regarding cognitive performance under various dietary conditions. She found that the impaired glucose tolerance group showed difficulties in 12 of 27 cognitive test outcomes, including word recognition, visual verbal learning test, visual spatial learning test, psychomotor test and Corsi block-tapping. The impaired glucose tolerance group was made up of all middle-aged women who appeared to be in general good health ... She pointed to a 2009 Japanese study of 129 people in their 80s, 55 of whom had impaired glucose tolerance or Type 2 diabetes. All the subjects in the study consumed more than 30 grams of dietary fiber per day and exercised two to four times per week over a two-year period. Within that timeframe, the 36 people with impaired glucose tolerance showed improvements in delayed recall and block design tests. The Type 2 diabetes group showed improvement in dementia, delayed recall and their mental state"

What are fructooliogosaccharides and how do they provide digestive, immunity and bone health benefits? - Science Daily, 7/16/13 - "Fructooliogosaccharides are naturally found in chicory, onions, asparagus, wheat, tomatoes and other fruits, vegetables and grains. They also can be derived from cane sugar and seaweed for use as a low-calorie (1.5 -- 2 Kcal/g) food sweetener and supplement. As scFOS provides approximately 30-to-50 percent of the sweetness of regular sugar, it can be used to enhance flavor and lower the amount of sugar in a food product ... In addition, scFOS are considered prebiotics. After they are consumed, fructooliogosaccharides move to the large intestine to stimulate the production of microbiota in the colon and gastrointestinal track ... The regular addition of scFOS to the diet is "ideal for maintaining mineral density and (bone) strength ... Most Americans, including many formula-fed infants and children, do not get enough scFOS" - See inulin at Amazon.com.

New Risk With ADT in Prostate Cancer: Kidney Injury - Medscape, 7/16/13 - "In the study of more than 10,000 men with prostate cancer, the therapy, which has been tied to diabetes, heart disease, stroke, and other conditions, was significantly associated with an increased risk for acute kidney injury (AKI). This serious adverse event has a mortality rate of 50% ... ADT reduces testosterone levels, which leads to a hypogonadal condition marked by metabolic changes such as dyslipidemia, hyperglycemia, and an increase in fat mass"

Therapeutic Potential of Turmeric in Alzheimer's Disease: Curcumin or Curcuminoids? - Phytother Res. 2013 Jul 19 - "Alzheimer's disease (AD) is the most common form of dementia. There is limited choice in modern therapeutics, and drugs available have limited success with multiple side effects in addition to high cost. Hence, newer and alternate treatment options are being explored for effective and safer therapeutic targets to address AD. Turmeric possesses multiple medicinal uses including treatment for AD. Curcuminoids, a mixture of curcumin, demethoxycurcumin, and bisdemethoxycurcumin, are vital constituents of turmeric. It is generally believed that curcumin is the most important constituent of the curcuminoid mixture that contributes to the pharmacological profile of parent curcuminoid mixture or turmeric. A careful literature study reveals that the other two constituents of the curcuminoid mixture also contribute significantly to the effectiveness of curcuminoids in AD. Therefore, it is emphasized in this review that each component of the curcuminoid mixture plays a distinct role in making curcuminoid mixture useful in AD, and hence, the curcuminoid mixture represents turmeric in its medicinal value better than curcumin alone" - See curcumin products at Amazon.com.

A High-Salt Diet Further Impairs Age-Associated Declines in Cognitive, Behavioral, and Cardiovascular Functions in Male Fischer Brown Norway Rats - J Nutr. 2013 Jul 17 - "we tested the effect of high salt (HS) on anxiety, learning-memory function, and blood pressure (BP) in male Fischer brown Norway (FBN) rats. Adult (A; 2 mo) and old (O; 20 mo) male rats were fed normal-salt (NS; 0.4% NaCl) or HS (8% NaCl) diets for 4 wk after being implanted with telemeter probes for conscious BP measurement. Thereafter, tests to assess anxiety-like behavior and learning-memory were conducted. The rats were then killed, and samples of plasma, urine, and brain tissue were collected. We found that systolic BP was higher in O-NS (117 +/- 1.2 mm Hg) than in A-NS (105 +/- 0.8 mm Hg) rats (P < 0.05). Furthermore, BP was higher in O-HS (124 +/- 1.4 mm Hg) than in O-NS (117 +/- 1.2 mm Hg) rats (P < 0.05). Moreover, anxiety-like behavior (light-dark and open-field tests) was not different between A-NS and O-NS rats but was greater in O-HS rats than in A-NS, O-NS, or A-HS rats (P < 0.05). Short-term memory (radial arm water maze test) was similar in A-NS and O-NS rats but was significantly impaired in O-HS rats compared with A-NS, O-NS, or A-HS rats (P < 0.05). Furthermore, oxidative stress variables (in plasma, urine, and brain) as well as corticosterone (plasma) were greater in O-HS rats when compared with A-NS, O-NS, or A-HS rats (P < 0.05). The antioxidant enzyme glyoxalase-1 expression was selectively reduced in the hippocampus and amygdala of O-HS rats compared with A-NS, O-NS, or A-HS rats (P < 0.05), whereas other antioxidant enzymes, glutathione reductase 1, manganese superoxide dismutase (SOD), and Cu/Zn SOD remained unchanged. We suggest that salt-sensitive hypertension and behavioral derangement are associated with a redox imbalance in the brain of aged FBN rats"

Consumption of coffee, not green tea, is inversely associated with arterial stiffness in Japanese men - Eur J Clin Nutr. 2013 Jul 17 - "540 eligible men who enrolled in the baseline survey of a cohort study in Tokushima Prefecture, Japan ... Coffee consumption was inversely associated with arterial stiffness independent of known atherosclerotic risk factors, and this association was partly mediated by reduced circulating triglycerides"

Olive oil has a beneficial effect on impaired glucose regulation and other cardiometabolic risk factors. Di@bet.es study - Eur J Clin Nutr. 2013 Jul 17 - "A total of 4572 individuals aged 18 years in 100 clusters (health centers) were randomly selected with a probability proportional to population size ... Around 90% of the Spanish population use olive oil, at least for dressing, and slightly fewer for cooking or frying. The preference for olive oil is related to age, educational level, alcohol intake, body mass index and serum glucose, insulin and lipids. People who consume olive oil (vs sunflower oil) had a lower risk of obesity (odds ratio (OR)=0.62 (95% confidence interval (CI)=0.41-0.93, P=0.02)), impaired glucose regulation (OR=0.49 (95% CI=0.28-0.86, P=0.04)), hypertriglyceridemia (OR=0.53 (95% CI=0.33-0.84, P=0.03)) and low HDL cholesterol levels (OR=0.40 (95% CI=0.26-0.59, P=0.0001))"

Effects of Metformin Dose on Cancer Risk Reduction in Patients with Type 2 Diabetes Mellitus: A 6-Year Follow-up Study - Pharmacotherapy. 2013 Jul 17 - "Longitudinal Health Insurance Database ... A total of 65,754 age- and gender-matched patients without diabetes and no previous cancer diagnosis were extracted from the database ... Our results revealed dose-dependent effects of metformin on cancer risk and cancer onset times. A significant decrease in cancer risk was found in the monotherapy group who received more than 360 defined daily doses (DDDs) of metformin (hazard ratio [HR] 0.40, 95% confidence interval [CI] 0.24-0.66). The greatest decrease in cancer risk was observed in patients who took more than 1080 DDDs (HR 0.27, 95% CI 0.09-0.84). Significantly greater dose-dependent effects were seen in patients who used metformin in combination with other antidiabetic drugs" - See metformin at The Antiaging Store.

The protective effect of coffee consumption on cutaneous melanoma risk and the role of GSTM1 and GSTT1 polymorphisms - Cancer Causes Control. 2013 Jul 17 - "case-control study was conducted in the inpatient wards of IDI-San Carlo Rome, Italy, including 304 incident cases of cutaneous melanoma and 305 controls ... High frequency of coffee drinking (>once daily), compared with low-frequency consumption of coffee (≤7 times weekly) was associated with a protective effect for cutaneous melanoma (OR 0.46"

Rosiglitazone and Outcomes for Patients with Diabetes and Coronary Artery Disease in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) Trial - Circulation. 2013 Jul 15 - "Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial ... 4.5 yrs of follow-up ... After multivariable adjustment, among patients treated with rosiglitazone, mortality was similar (HR 0.83; 95% CI, 0.58 to 1.18) while there was a lower adjusted incidence of composite death, MI, and stroke (hazard ratio (HR) 0.72; 95% confidence interval (CI), 0.55 to 0.93) and stroke (HR 0.36, 95% CI 0.16 to 0.86), and a higher incidence of fractures (HR 1.62, 95% CI 1.05 to 2.51); the incidence of MI (HR 0.77; 95% CI, 0.54 to 1.10) and CHF (HR 1.22, 95%CI, 0.84 to 1.82) were not significantly different. Among propensity matched patients rates of major ischemic cardiovascular events and CHF were not significantly different"

Protective effects of dietary carotenoids on risk of hip fracture in men: The Singapore Chinese Health Study - J Bone Miner Res. 2013 Jul 16 - "used data from the Singapore Chinese Health Study, a prospective cohort of 63,257 men and women who were of ages 45-74 years between 1993 and 1998 ... validated food frequency questionnaire. During a mean follow-up of 9.9 years, we identified 1,630 hip fracture incident cases. Among men, consumption of vegetables was associated with lower hip fracture risk. Similarly, dietary total carotenoids and specific carotenoids, α-, β-carotene and lutein/zeaxanthin were inversely associated with hip fracture risk. Compared to men in the lowest quartile of nutrient density, men in the highest quartile had statistically significant 26% to 39% risk reduction ... There was no association between dietary carotenoids or vegetables/fruits and hip fracture risk among women. This study suggests that adequate intake of vegetables may reduce risk of osteoporotic fractures among elderly men and that the antioxidant effects of carotenoids may counteract the mechanism of osteoporosis related to leanness" - See Jarrow Formulas, CarotenALL at Amazon.com.

Curcumin I Mediates Neuroprotective Effect Through Attenuation of Quinoprotein Formation, p-p38 MAPK Expression, and Caspase-3 Activation in 6-Hydroxydopamine Treated SH-SY5Y Cells - Phytother Res. 2013 Jul 16 - "6-Hydroxydopamine (6-OHDA) selectively enters dopaminergic neurons and undergoes auto-oxidation resulting in the generation of reactive oxygen species and dopamine quinones, subsequently leading to apoptosis. This mechanism mimics the pathogenesis of Parkinson's disease and has been used to induce experimental Parkinsonism in both in vitro and in vivo systems ... curcumin I (diferuloylmethane) purified from Curcuma longa ... Our results clearly demonstrated that curcumin I protects neurons against oxidative damage, as shown by attenuation of p-p38 expression, caspase-3-activation, and toxic quinoprotein formation, together with the restoration of p-TH levels. This study provides evidence for the therapeutic potential of curcumin I in the chemoprevention of oxidative stress-related neurodegeneration" - See curcumin products at Amazon.com.

Quercetin Protects Mouse Brain against Lead-induced Neurotoxicity - J Agric Food Chem. 2013 Jul 15 - "Mice were exposed to lead acetate (20 mg/kg body weight/day) intragastrically with or without QE (15 and 30 mg/kg body weight/day) co-administration for three months. Our data showed that QE significantly prevented Pb-induced neurotoxicity in a dose-dependent manner. In exploring the underlying mechanisms of QE action, we found QE administration decreased Pb contents in blood (13.2%, 19.1%) and brain (17.1%, 20.0%). QE markedly increased NO production (39.1%, 61.1%) and PKA activity (51.0%, 57.8%) in brains of Pb-treated mice. Additionally, QE remarkably suppressed Pb-induced oxidative stress in mouse brain. Western blot analysis showed that QE increased the phosphorylations of Akt, CaMKII nNOS, eNOS and CREB in brains of Pb-treated mice" - See quercetin at Amazon.com.

News & Research:

  • Specific Fish Oils May Protect Against Breast Cancer - Medscape, 6/27/13 - "The consumption of higher levels of dietary marine n-3 polyunsaturated fatty acids (PUFAs) is associated with a 14% lower risk for breast cancer than lower levels of consumption ... They found that marine n-3 PUFAs were associated with a 14% reduction in the risk for breast cancer (relative risk [RR] for highest vs lowest intake, 0.86) ... no significant association was observed for exposure to alpha linolenic acid (ALA), which is contained in some nuts and in vegetable oils. About half of the studies in the meta-analysis contained data on ALA. Both ALA and n-3 PUFAs are types of omega-3 fatty acids" - [Science Daily] - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Could a Diet High in Fish and Flax Help Prevent Broken Hips? - Science Daily, 6/27/13 - "The study showed that higher levels of omega-3 fatty acids from both plant and fish sources in those blood cells were associated with a lower likelihood of having fractured a hip ... The study also showed that as the ratio of omega-6 fatty acids to omega-3s increased, so did the risk for hip fracture ... Inflammation is associated with an increased risk of bone loss and fractures, and omega-3 fatty acids are believed to reduce inflammation ... omega-3 fatty acids have anti-inflammatory properties and omega-6 fatty acids seem to have both anti- and pro-inflammatory effects ... women who had the highest ratio of omega-6 to omega-3 fatty acids had nearly twice the risk of hip fractures compared to women with the lowest ratios. The current typical American diet contains between 15 and 17 times more omega-6 than omega-3, a ratio that previous research has suggested should be lowered to 4-to-1, or even 2-to-1, by increasing omega-3s, to improve overall health. The primary omega-6 fatty acid in the diet is linoleic acid, which composes about 99 percent of Americans' omega-6 intake and is found in corn, soybean, safflower and sunflower oils"
  • Marine n-3 Polyunsaturated Fatty Acids - Medscape, 6/11/13 - "Sarcopenia is the age-related loss of muscle mass that results in a reduction in skeletal muscle function, quality of life and an increased risk of falls. Older muscle has an 'anabolic resistance' to both nutrients and exercise, with the precise underlying mechanism still to be elucidated. The n-3 polyunsaturated fatty acids found in fish oil can be incorporated into the membranes of skeletal muscles, where they may have anti-inflammatory effects. This alteration in muscle membrane fatty acid composition may have anabolic effects in aging muscle and, thus, be useful in the treatment of sarcopenia ... The current data presented suggest that n-3 PUFAs may be of benefit in the treatment of sarcopenia"
  • Omega-3 fatty acids may help heal a broken heart - Science Daily, 5/30/13 - "The potency of these compounds corresponds to concentrations that have been measured in the blood of human subjects taking high dose fish oil supplements for short periods of time. In rabbits, researchers treated the artery with RvD at the time of the balloon angioplasty procedure by infusing the drug directly into the vessel, and found that this one-time treatment reduced inflammation and subsequent scarring of the vessel after one month"
  • Fish Oil Supplements May Help Fight Against Type 2 Diabetes - Science Daily, 5/22/13 - "Fish oil supplements, also called omega 3 fatty acid capsules, raise levels of adiponectin in the bloodstream. Adiponectin is an important hormone that has beneficial effects on metabolic processes like glucose regulation and the modulation of inflammation. In long-term human studies, higher levels of adiponectin are associated with lower risks of type 2 diabetes and coronary heart disease ... The meta-analysis reviewed and analyzed results from 14 randomized, placebo-controlled clinical trials"
  • Fish oil may help the heart beat mental stress - Science Daily, 5/22/13 - "volunteers who took fish oil supplements for several weeks had a blunted response to mental stress in several measurements of cardiovascular health, including heart rate and muscle sympathetic nerve activity (MSNA), part of the "fight or flight" response, compared to volunteers who took olive oil instead. The results may explain why taking fish oil could be beneficial to the heart and might eventually help doctors prevent heart disease in select populations"
  • Fish oil may stall effects of junk food on brain - Science Daily, 5/14/13 - "high-fat diets could disrupt neurogenesis, a process that generates new nerve cells, but diets rich in omega-3s could prevent these negative effects by stimulating the area of the brain that control feeding, learning and memory ... Excessive intake of certain macronutrients, the refined sugars and saturated fats found in junk food, can lead to weight gain, disrupt metabolism and even affect mental processing ... These changes can be seen in the brain's structure, including its ability to generate new nerve cells, potentially linking obesity to neurodegenerative diseases ... omega-3 fish oils can reverse or even prevent these effects ... omega-3s restore normal function by interfering with the production of these inflammatory molecules, suppressing triglycerides, and returning these nerve growth factors to normal ... Fish oils don't appear to have a direct impact on weight loss, but they may take the brakes off the detrimental effects of some of the processes triggered in the brain by high-fat diets. They seem to mimic the effects of calorie restrictive diets and including more oily fish or fish oil supplements in our diets could certainly be a positive step forward for those wanting to improve their general health"
  • Eating fish associated with lower risk of dying among older adults: Risk of dying from heart disease significantly lowered - Science Daily, 4/1/13 - "Older adults who have higher blood levels of omega-3 fatty acids -- found in fatty fish and seafood -- may be able to lower their overall mortality risk by as much as 27% and their mortality risk from heart disease by about 35% ... older adults who had the highest blood levels of the fatty acids found in fish lived, on average, 2.2 years longer than those with lower levels ... The researchers examined 16 years of data from about 2,700 U.S. adults aged 65 or older who participated in the Cardiovascular Health Study (CHS), a long-term study supported by the National Heart, Lung, and Blood Institute ... One type in particular -- docosahexaenoic acid, or DHA -- was most strongly related to lower risk of coronary heart disease (CHD) death (40% lower risk), especially CHD death due to arrhythmias (electrical disturbances of the heart rhythm) (45% lower risk). Of the other blood fatty acids measured -- eicosapentaenoic acid (EPA) and docosapentaenoic acid (DPA) -- DPA was most strongly associated with lower risk of stroke death, and EPA most strongly linked with lower risk of nonfatal heart attack"
  • High Intake of Dietary Long-Chain ω-3 Fatty Acids Is Associated With Lower Blood Pressure in Children Born With Low Birth Weight: NHANES 2003-2008 - Hypertension. 2013 Mar 4 - "Reduced fetal growth is associated with increased systolic blood pressure ... In the 354 participants with reduced birth weight, when compared with children with the lowest tertile of intake, those who had the highest tertile of dietary eicosapentaenoic acid and docosahexaenoic acid intake had significantly lower systolic blood pressure (-4.9 mm Hg [95% confidence interval, -9.7 to -0.1]) and pulse pressure (-7.7 mm Hg [95% confidence interval, -15.0 to -0.4])" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Specifically, it also reduced sunlight-induced suppression of the immune system, known as immunosuppression, which affects the body's ability to fight skin cancer and infection ... it was the first time the research had been carried out on humans"
  • Omega-3s inhibit breast cancer tumor growth, study finds - Science Daily, 2/21/13 - "A lifelong diet rich in omega-3 fatty acids can inhibit growth of breast cancer tumours by 30 per cent ... the researchers created a novel transgenic mouse that both produces omega-3 fatty acids and develops aggressive mammary tumours. The team compared those animals to mice genetically engineered only to develop the same tumours ... Mice producing omega-3s developed only two-thirds as many tumours -- and tumours were also 30-per-cent smaller -- as compared to the control mice"
  • Fish oil may protect dialysis patients from sudden cardiac death - Science Daily, 2/6/13 - "We found that higher levels of omega-3 fatty acids in the blood of patients who were just starting hemodialysis were very strongly associated with a lower risk of sudden cardiac death over the first year of their treatment ... The five-year survival rate for patients on hemodialysis is 35 percent, with the risk of death highest in the first few months of starting treatment. The most common cause of death in these patients is sudden cardiac death, which accounts for about one out of every four deaths"
  • Omega-3-Rich Ground Beef Available Soon - Science Daily, 2/4/13 - "The U.S. currently does not have a recommended daily intake of omega-3s, though many doctors and nutritionists recommend between 1,200-1,600 milligrams daily ... A quarter-pound hamburger made of the enriched ground beef has 200 milligrams of omega-3s" - See Mega Twin EPA at Amazon.com which has 765 milligrams of omega-3 in one capsule.  So you'd have to eat 3.825 hamburgers to get the omega-3 in one capsule.  At 330 calories per hamburger, that's 1262 calories compared to 10 calories for the capsule.
  • Limiting Polyunsaturated Fatty Acid Levels in Pregnancy May Influence Body Fat of Children - Science Daily, 1/10/13 - "mothers who have higher levels of n-6 polyunsaturated fatty acids (PUFAs), which are found in cooking oils and nuts, during pregnancy have fatter children ... assessed the fat and muscle mass of 293 boys and girls at four and six years, who are part of the Southampton Women's Survey (SWS), a large prospective mother-offspring cohort ... the higher the level of n-3 the less fat and more muscle and bone in the baby ... This could suggest that a pregnancy supplementation strategy would be beneficial"
  • Association Between use of Specialty Dietary Supplements and C-Reactive Protein Concentrations - Medscape, 12/28/12 - "In summary, this study adds support to laboratory research and to some human studies which suggest that glucosamine, chondroitin, and fish oil may reduce systemic inflammation. In doing so, this study adds biologic plausibility to previous studies which have shown beneficial effects of these supplements on chronic diseases. Given the number of diseases with which inflammation is associated, such as cancer and cardiovascular disease, there is a need to find safe and effective ways to reduce inflammation. Research suggests that these 3 supplements have excellent safety profiles, [88–92] supporting their potential role in disease prevention" - See glucosamine products at Amazon.com, chondroitin sulfate at Amazon.com, Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Glucosamine, Chondroitin, Fish Oil May Reduce Inflammation - Medscape, 11/27/12 - "Inflammation is now recognized as a factor in cancer and cardiovascular disease as well as many rheumatoid diseases ... the researchers found hs-CRP reductions of 17% (95% confidence interval [CI], 7% - 26%) with glucosamine, 22% (95% CI, 8% - 33%) with chondroitin, and 16% (95% CI, 0.3% - 29%) with fish oil compared with participants who did not take the supplements"
  • Eating more fish could reduce postpartum depression - Science Daily, 11/15/12 - "Low levels of omega-3 may be behind postpartum depression ... Because omega-3 is transferred from the mother to her fetus and later to her breastfeeding infant, maternal omega-3 levels decrease during pregnancy, and remain lowered for at least six-weeks following the birth" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Omega-3 intake heightens working memory in healthy young adults - Science Daily, 10/25/12 - "In the first study of its kind, researchers at the University of Pittsburgh have determined that healthy young adults ages 18-25 can improve their working memory even further by increasing their Omega-3 fatty acid intake ... After six months of taking Lovaza -- an Omega-3 supplement approved by the Federal Drug Administration -- the participants were asked to complete this series of outpatient procedures again. It was during this last stage, during the working memory test and blood sampling, that the improved working memory of this population was revealed" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com and probiotic products at Amazon.com.
  • New link between high-fat 'Western' diet and atherosclerosis identified - Science Daily, 10/8/12 - "endothelial lipase (EL), an enzyme associated with the development of atherosclerosis ... In the current study, a strain of mice susceptible to atherosclerosis was fed a normal diet enriched with either palmitic acid (a common saturated fat) or eicosapentaenoic acid (an omega-3 fatty acid, or polyunsaturated fat, found in fish oil, among other foods). After 12 weeks, the mice's aortas were examined for changes in the expression of EL and inflammatory factors. Aortas of mice fed the saturated fat diet showed a significant increase in EL and detrimental changes in inflammatory factors, while those of mice fed the polyunsaturated fat diet showed a significant decrease in EL and beneficial changes in inflammatory factors ... when the macrophages were given rosiglitazone, the expression of EL increased markedly. The addition of omega-3 fatty acids to the cells blocked this increase. "This would suggest that besides raising LDL cholesterol levels, rosiglitazone can raise the risk of cardiovascular disease by increasing EL,""
  • Prenatal mercury exposure may be linked to risk of ADHD-related behaviors; Fish consumption may be linked to lower risk - Science Daily, 10/8/12 - "Nonoccupational methylmercury exposure comes primarily from eating fish, and the U.S. Environmental Protection Agency and the U.S. Food and Drug Administration have recommended pregnant women limit their total fish intake to no more than two, six-ounce servings per week. However, fish is also a source of nutrients, such as omega-3 fatty acids, which have been shown to benefit brain development, potentially confounding mercury-related risk estimates ... analyzed data from the New Bedford birth cohort, a group of infants born between 1993 and 1998, to investigate the association of peripartum maternal hair mercury levels (n=421) and prenatal fish intake (n=515) with ADHD-related behaviors at age 8 years ... In this population-based prospective cohort study, hair mercury levels were consistently associated with ADHD-related behaviors, including inattention and hyperactivity/impulsivity. We also found that higher prenatal fish consumption was protective for these behaviors"
  • Omega-3 supplements may slow a biological effect of aging - Science Daily, 10/1/12 - "In the study, lengthening of telomeres in immune system cells was more prevalent in people who substantially improved the ratio of omega-3s to other fatty acids in their diet ... Omega-3 supplementation also reduced oxidative stress, caused by excessive free radicals in the blood, by about 15 percent compared to effects seen in the placebo group ... Study participants took either 2.5 grams or 1.25 grams of active omega-3 polyunsaturated fatty acids ... The supplements were calibrated to contain a ratio of the two cold-water fish oil fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), of seven to one ... the typical American diet tends to be heavy on omega-6 fatty acids and comparatively low in omega-3s that are naturally found in cold-water fish such as salmon and tuna. While the ratio of omega-6 to omega-3 fatty acids averages about 15-to-1, researchers tend to agree that for maximum benefit, this ratio should be lowered to 4-to-1, or even 2-to-1 ... when the researchers analyzed the participants' omega-6 to omega-3 ratio in relationship to telomere lengthening, a lower ratio was clearly associated with lengthened telomeres ... omega-3 supplements lowered IL-6 by 10 to 12 percent, depending on the dose. By comparison, those taking a placebo saw an overall 36 percent increase in IL-6 by the end of the study ... This finding strongly suggests that inflammation is what's driving the changes in the telomeres"
  • Omega-3 lowers inflammation in overweight older adults - Science Daily, 6/21/12 - "Chronic inflammation is linked to numerous conditions, including coronary heart disease, Type 2 diabetes, arthritis and Alzheimer's disease, as well as the frailty and functional decline that can accompany aging ... Participants received either a placebo or one of two different doses of omega-3 fatty acids -- either 2.5 grams or 1.25 grams per day ... After four months, participants who had taken the omega-3 supplements had significantly lower levels in their blood of two proteins that are markers of inflammation, also called pro-inflammatory cytokines. The low-dose group showed an average 10 percent decrease in the cytokine interleukin-6 (IL-6), and the high-dose group's overall IL-6 dropped by 12 percent. In comparison, those taking a placebo saw an overall 36 percent increase in IL-6 by the end of the study ... The current typical American diet contains between 15 and 17 times more omega-6 than omega-3, a ratio that researchers suggest should be lowered to 4-to-1, or even 2-to-1, to improve overall health"

  • Why omega-3 oils help at the cellular level - Science Daily, 5/15/12 - "The scientists fed mouse macrophages -- a kind of white blood cell -- three different kinds of fatty acid: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and arachidonic acid (AA). EPA and DHA are major polyunsaturated omega-3 fatty acids, essential to a broad range of cellular and bodily functions, and the primary ingredient in commercial fish oil dietary supplements. AA is a polyunsaturated omega-6 fatty acid prevalent in the human diet ... They discovered that omega-3 fatty acids inhibit an enzyme called cyclooxygenase (COX), which produces the prostaglandin hormones that spark inflammation. The action is similar to what happens when one takes an aspirin, which disrupts the COX-2 signaling pathway, thus reducing inflammation and pain ... On the other hand ... omega-3 oils do not inhibit another group of enzymes called lipoxygenases (LOX), which are also produced by stimulated macrophages. One type of generated LOX enzyme in turn produces fat-signaling molecules called leukotrienes, which are pro-inflammatory. But Norris noted that LOX enzymes may also generate anti-inflammatory compounds called resolvins from EPA and DHA"
  • Nutrition: More Omega-3, Less of a Suspect Protein - NYTimes.com, 5/7/12 - "Amyloid plaques and tangles in the brain are characteristic of Alzheimer’s disease and are known to increase the risk for mental decline ... higher levels of omega-3 intake were associated with significantly lower beta-amyloid blood levels"
  • Eating fish, chicken, nuts may lower risk of Alzheimer's disease - Science Daily, 5/2/12 - "A new study suggests that eating foods that contain omega-3 fatty acids, such as fish, chicken, salad dressing and nuts, may be associated with lower blood levels of a protein related to Alzheimer's disease and memory problems ... 1,219 people older than age 65, free of dementia, provided information about their diet for an average of 1.2 years before their blood was tested for the beta-amyloid. Researchers looked specifically at 10 nutrients, including saturated fatty acids, omega-3 and omega-6 polyunsaturated fatty acids, mono-unsaturated fatty acid, vitamin E, vitamin C, beta-carotene, vitamin B12, folate and vitamin D ... the more omega-3 fatty acids a person took in, the lower their blood beta-amyloid levels. Consuming one gram of omega-3 per day (equal to approximately half a fillet of salmon per week) more than the average omega-3 consumed by people in the study is associated with 20 to 30 percent lower blood beta-amyloid levels ... Other nutrients were not associated with plasma beta-amyloid levels" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Fish oil added to yogurt may help consumers meet daily nutritional requirements - Science Daily, 3/28/12 - "In a preliminary study, tasters could not differentiate between low levels of fish and butter oils in unflavored yogurt, but they could discern yogurt flavored with oxidized fish oil, which has a strong fishy taste" - Hmmm!!!

The compound is produced from EPA -- Eicosapentaenoic Acid -- an Omega-3 fatty acid found in fish and in fish oil ... During the experiments, the researchers injected each mouse with about 600 nanograms of D12-PGJ3 each day for a week. Tests showed that the mice were completely cured of the disease. The blood count was normal, and the spleen returned to normal size. The disease did not relapse ... The researchers focused on D12-PGJ3 because it killed the leukemia stem cells, but had the least number of side effects"
  • Some Fish Oil Supplements Fishy on Quality - WebMD, 12/7/11 - "None of the fish oil supplements contained contaminants, such as lead, mercury, or PCBs, that exceeded levels set by USP or the European Union ... the total PCB amounts in four brands (CVS Natural, GNC Triple Organic, Nature’s Bounty Odorless, and Sundown Naturals) were below the USP safe limit but within the range that would require a warning label under California’s Proposition 65, 90 parts per billion ... For the report, the consumer agency purchased three lots of 15 different top-selling brands of fish oil supplements online and in the New York metropolitan area ... Two of the three samples of Kirkland Signature Enteric 1200 fish oil supplements had an enteric coating (designed to prevent a fishy aftertaste) that did not disintegrate properly. The coating may break up in the stomach rather than in the small intestine, as desired for proper absorption by the body" - Note:  So those bargains at Costco may not be such a bargain if they aren't absorbed.
  • Young women may reduce heart disease risk eating fish with omega 3 fatty acids, study finds - Science Daily, 12/5/11 - "In the first population-based study in women of childbearing age, those who rarely or never ate fish had 50 percent more cardiovascular problems over eight years than those who ate fish regularly. Compared to women who ate fish high in omega-3 weekly, the risk was 90 percent higher for those who rarely or never ate fish ... Fish oil contains long chain omega-3 polyunsaturated fatty acids, which are believed to protect against heart and vascular disease. Few women in the study took fish oil supplements, so these were excluded from the analyses and the results were based on the dietary intake of omega-3 fatty acids, not intake from supplements"
  • Eating fish can reduce the risk of diabetes - Science Daily, 11/11/11 - "the consumption of fish is associated with a decreased prevalence of diabetes and lower glucose concentrations whereas the consumption of red meat, especially cured meats is related to increased weight gain and obesity ...

In contrast, fish appears in the Mediterranean diet and has health benefits for the heart"
  • You are what you eat: Low fat diet with fish oil slows growth of human prostate cancer cells, study suggests - Science Daily, 10/25/11 - "Men who ate a low-fat diet with fish oil supplements for four to six weeks before having their prostate removed had slower cancer-cell growth in their prostate tissue than men who ate a traditional, high-fat Western diet ... The short-term study also found that blood obtained from patients after the low-fat, fish oil diet slowed the growth of prostate cancer cells in a test tube, while blood from men on the Western diet did not slow cancer growth ... Preclinical studies suggest that lowering dietary omega-6 fatty acids from corn oil and increasing omega-3 fatty acids from fish oil decreases the risk of prostate cancer development and progression," the study states. "We found this diet intervention resulted in a decrease in omega-6 vs. omega-3 fatty acid ratios in benign and malignant prostate tissue and a decrease in malignant cell proliferation"
  • Boosting mental performance with fish oil? - Science Daily, 10/21/11 - "overall, taking either of two different types of fish oil supplement for three months had no consistent impact on mental function in 18 -- 35-year-olds, however they did find evidence of reduced mental fatigue and faster reaction times. Contrary to popular belief, these results suggest that taking omega-3 or fish oil supplements may not have an immediate or measureable impact on mental performance in healthy young adults, possibly due to the fact that this population is already performing at its mental peak or that higher doses or longer than 12 weeks supplementation are required ... Interestingly, in the second of these studies it was found that taking DHA-rich fish oil over the same time period did increase blood flow to active areas of the brain during performance of similar mental tasks. The researchers claim these findings could have implications for mental function later on in life, as evidence suggests regularly eating oily fish or taking omega-3 supplements may prevent cognitive decline and dementia, and increased blood flow to the brain may be a mechanism by which this occurs"
  • Omega-3 fatty acids shown to prevent or slow progression of osteoarthritis - Science Daily, 10/17/11 - "New research has shown for the first time that omega-3 in fish oil could "substantially and significantly" reduce the signs and symptoms of osteoarthritis ... omega-3-rich diets fed to guinea pigs, which naturally develop osteoarthritis, reduced disease by 50 per cent compared to a standard diet ... Furthermore, there was strong evidence that omega-3 influences the biochemistry of the disease, and therefore not only helps prevent disease, but also slows its progression, potentially controlling established osteoarthritis ... The only way of being certain that the effects of omega-3 are as applicable to humans as demonstrated in guinea pigs is to apply omega-3 to humans. However, osteoarthritis in guinea pigs is perhaps the most appropriate model for spontaneous, naturally occurring osteoarthritis, and all of the evidence supports the use of omega-3 in human disease ... Most diets in the developed world are lacking in omega-3, with modern diets having up to 30 times too much omega-6 and too little omega-3. Taking omega-3 will help redress this imbalance and may positively contribute to a range of other health problems such as heart disease and colitis"
  • Omega-3 may ease depression symptoms, slash dementia risk: RCT - Nutra USA, 9/23/11 - "recruited 50 people over the age of 65 to participate in their six-month double-blind, randomized controlled trial ... Participants received daily supplements of EPA- or DHA-rich fish oil, or the omega-6 linoleic acid (LA, 2.2 grams per day). The EPA-rich supplement provided 1.67 grams of EPA and 0.16 grams of DHA, while the DHA-rich supplement provided 1.55 grams of DHA and 0.40 grams of EPA ... compared with the group receiving the LA supplements, the EPA-rich supplement group displayed higher scores on the Geriatric Depression Scale ... On the other hand, the DHA group displayed improvements in verbal fluency ... These results indicate that DHA-rich and EPA-rich fish oils may be effective for depressive symptoms and health parameters, exerting variable effects on cognitive and physical outcomes" - [Abstract]
  • Omega-3 supplements show benefits against anxiety: Human data - Nutra USA, 9/14/11 - "the Ohio State researchers recruited 68 medical students to participate in their parallel group, placebo-controlled, double-blind trial. The med students were given either placebo capsules or omega-3 capsules containing 2085 mg of EPA (eicosapentaenoic acid) and 348 mg DHA (docosahexanoic acid) ... Results showed a 14% reduction in levels of the production of pro-inflammatory interleukin 6 (IL-6), as well as a 20% reduction in anxiety symptoms in the omega-3 group, compared to the placebo group ... Proinflammatory cytokines promote secretion of corticotropin-releasing hormone (CRH), a primary gateway to hormonal stress responses; CRH also stimulates the amygdala, a key brain region for fear and anxiety. Accordingly, alterations in inflammation could also influence anxiety" - [Abstract] - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.  Note:  CRH increases cortisol.  See:
  • Maternal omega-3 intake may influence childhood allergy - Nutra USA, 9/12/11 - "Omega-3 fatty acids may aid the development of the infant gut and improve how gut immune cells respond to bacteria and foreign substances, making the baby less likely to suffer from allergies in the long term, according to new research in pigs ... These findings suggest that feeding fatty acids of the omega-3 family during pregnancy and lactation impact newborn intestinal barrier function ... such changes “are likely to reduce the risk of developing allergies in later life" ... The end result is that the baby's immune system may develop and mature faster – leading to better immune function and less likelihood of suffering allergies ... the pig intestine is an excellent model of the human gut, however, so they are hopeful that the findings can be extrapolated" - [Abstract]
  • Omega-3 Effective for Treating Child ADHD - Medscape, 9/8/11 - "In an evaluation of 10 trials with 699 total children with ADHD, investigators found that those who received omega-3 supplements had a "small but significant" improvement in symptom severity compared with those who were given placebo.

Omega-3 supplements that included higher doses of eicosapentaenoic acid were also significantly associated with lowering ADHD symptoms ... There were no significant differences found for any dose of docosahexaenoic acid or α-linolenic acid, or between omega-3 monotherapy vs augmenting traditional ADHD medications with omega-3" - See Mega Twin EPA at Amazon.com.
  • Marine, but not plant, omega-3s may boost heart health for women: Study - Nutra USA, 9/7/11 - "High intakes of long chain omega-3 eicosapentaenoic acid (EPA, C20:5 n-3) and docosahexaenoic acid (DHA, C22:6 n-3) was associated with a 38% reduction in the risk of ischemic heart disease (IHD) in women, but not men ... Much attention has been paid to the conversion of ALA to the longer chain EPA, with many stating that this conversion is very small. Indeed, between 8 and 20 per cent of ALA is reportedly converted to EPA in humans, and between 0.5 and 9 per cent of ALA is converted to DHA ... high intakes of long chain omega-3s ranging from 0.45 to 11.2 grams per day were associated with a 38% reduction in IHD risk for women only" - [Abstract]
  • Fish oil's impact on cognition and brain structure identified in new study - Science Daily, 8/17/11 - "Researchers at Rhode Island Hospital's Alzheimer's Disease and Memory Disorders Center have found positive associations between fish oil supplements and cognitive functioning as well as differences in brain structure between users and non-users of fish oil supplements ... compared to non-users, use of fish oil supplements was associated with better cognitive functioning during the study. However, this association was significant only in those individuals who had a normal baseline cognitive function and in individuals who tested negative for a genetic risk factor for Alzheimer's Disease known as APOE4. This is consistent with previous research ... The unique finding, however, is that there was a clear association between fish oil supplements and brain volume ... In other words, fish oil use was associated with less brain shrinkage in patients taking these supplements during the ADNI study compared to those who didn't report using them"

HRs (Q5 to Q2 vs. Q1) were significantly elevated for %PPL palmitic acid. %PPL oleic acid was inversely associated with risk, HR = 0.62 [0.43, 0.91] (Q5 vs. Q1); p-trend = 0.04. No statistically significant linear trends were observed for dietary intakes. The HRs were elevated for moderate intakes of linoleic acid (Q2 and Q3 vs. Q1, 1.58 [1.10, 2.28] and 1.70 [1.18, 2.46], respectively), but the increase was not significant for higher intakes (Q4 and Q5). No association varied significantly by tumour aggressiveness (all p-homogeneity > 0.1). Prostate cancer risk was positively associated with %PPL SFA, largely attributable to palmitic acid and inversely associated with %PPL monounsaturated fatty acids, largely attributable to oleic acid. Higher risks were also observed for dietary n-6 polyunsaturated fats, primarily linoleic acid"

  • A low dietary ratio of omega-6 to omega-3 Fatty acids may delay progression of prostate cancer - Nutr Cancer. 2013;65(4):556-62 - "High amounts of omega-6 fatty acids have been linked with increased prostate cancer risk, whereas omega-3 fatty acids have been shown to inhibit PCa growth. However, because omega-3 and omega-6 are both essential fatty acids and part of a complete diet, it is more relevant to determine the ideal ratio of the two that would allow patients to benefit from the therapeutic properties of omega-3 fatty acids. LNCaP prostate cancer cells were treated with dietary-based ratios of omega-6 to omega-3 fatty acids under hormone-deprivation conditions, and effects on various cellular processes were determined. A low omega-6 to omega-3 PUFA ratio can delay the progression of cells toward castration-resistance by suppressing pathways involved in prostate cancer progression, such as the Akt/mTOR/NFκB axis. It also suppresses the expression of cyclin D1, and activation of caspase-3 and annexin V staining shows induction of proapoptotic events. Taken together, our data demonstrates that maintaining a low omega-6 to omega-3 fatty acids ratio can enhance efficacy of hormone ablation therapy"

The presence of prooxidant compounds in foods, however, renders them susceptible to oxidation during both storage and digestion ... We found that during digestion, the development of oxidation products occurs in the stomach compartment, and increased amounts of oxidation products became bioaccessible in the jejunal and ileal compartments. Inclusion of a polyphenol-rich grape seed extract (GSE) during the digestion decreased the amounts of oxidation products in the stomach compartment and intestinal dialysates (P < 0.05). In Caco-2 intestinal cells, the uptake of oxidized (n-3) PUFA was ~10% of the uptake of unoxidized PUFAs (P < 0.05) and addition of GSE or epigallocatechin gallate protected against the development of oxidation products, resulting in increased uptake of PUFAs (P < 0.05). These results suggest that addition of polyphenols during active digestion can limit the development of (n-3) PUFA oxidation products in the small intestine lumen and thereby promote intestinal uptake of the beneficial, unoxidized, (n-3) PUFAs" - See Jarrow Formulas OPCs + 95 at Amazon.com and green tea extract at Amazon.com.

In adjusted hazard models, lower hip fracture risk was associated with higher RBC a-linolenic acid [Hazard ratio (HR) Tertile 3 (T3): 0.44; 95% CI: 0.23-0.85; p for linear trend 0.0154)], eicosapentaenoic acid (HR T3: 0.46; 95% CI: 0.24-0.87; p for linear trend 0.0181) and total n-3 PUFAs (HR T3: 0.55; 95% CI: 0.30-1.01; p for linear trend 0.0492). Conversely, hip fracture nearly doubled with the highest RBC n-6/n-3 ratio (HR T3: 1.96; 95% CI: 1.03-3.70; p for linear trend 0.0399). RBC PUFAs were not associated with BMD. RBC PUFAs were indicative of dietary intake of marine n-3 PUFAs (Spearman's rho=0.45, p<0.0001), total n-6 PUFAs (rho=0.17, p<0.0001) and linoleic acid (rho= 0.09, p<0.05). These results suggest that higher RBC a-linolenic acid, as well as eicosapentaenoic acid and total n-3 PUFAs, may predict lower hip fracture risk. Contrastingly, a higher RBC n-6/n-3 ratio may predict higher hip fracture risk in postmenopausal women"

  • "Metabolic syndrome" in the brain: Deficiency in omega-3-fatty acid exacerbates dysfunctions in insulin receptor signaling and cognition - J Physiol. 2012 Apr 2 - "high-dietary fructose consumption leads to increase in insulin resistance index, insulin and triglyceride levels, which characterize MetS. Rats fed on an n-3 deficient diet showed memory deficits in Barnes Maze, which were further exacerbated by fructose intake. In turn, n-3 deficient diet and fructose interventions disrupted insulin receptor signaling in hippocampus as evidenced by a decrease in phosphorylation of insulin receptor and its downstream effector Akt. We found that high fructose consumption with n-3 deficient diet disrupts membrane homeostasis as evidenced by an increase in the ratio of n-6/n-3 fatty acids and levels of 4-hydroxynonenal (4-HNE), a marker of lipid peroxidation. Disturbances in brain energy metabolism due to n-3 deficiency and fructose treatments were evidenced by a significant decrease in AMPK phosphorylation and its upstream modulator LKB1 as well as a decrease in Sir2 levels. The decrease in phosphorylation of CREB, synapsin I and synaptophysin (SYP) levels by n-3 deficiency and fructose shows the impact of metabolic dysfunction on synaptic plasticity. All parameters of metabolic dysfunction related to the fructose treatment were ameliorated by the presence of dietary n-3 fatty acid. Results showed that dietary n-3 fatty acid deficiency elevates the vulnerability to metabolic dysfunction and impaired cognitive functions by modulating insulin receptor signaling and synaptic plasticity"

  • Effects of n-3 fatty acids on major cardiovascular events in statin users and non-users with a history of myocardial infarction - Eur Heart J. 2012 Feb 1 - "In statin users, an additional amount of n-3 fatty acids did not reduce cardiovascular events [HR(adj) 1.02; 95% confidence interval (CI): 0.80, 1.31; P = 0.88]. In statin non-users, however, only 9% of those who received EPA-DHA plus ALA experienced an event compared with 18% in the placebo group ... In patients with a history of MI who are not treated with statins, low-dose supplementation with n-3 fatty acids may reduce major cardiovascular events. This study suggests that statin treatment modifies the effects of n-3 fatty acids on the incidence of major cardiovascular events"
  • The Omega-3 Polyunsaturated Fatty Acid Eicosapentaenoic Acid Inhibits Mouse MC-26 Colorectal Cancer Cell Liver Metastasis Via Inhibition Of Prostaglandin E(2) -Dependent Cell Motility - Br J Pharmacol. 2012 Feb 2 - "Treatment with 5% (w/w) EPA-FFA was associated with a reduced MC-26 mouse CRC cell liver tumour burden compared with control animals (median liver weight 1.62g versus 1.03g; P < 0.034). Administration of 5% EPA-FFA was also linked to a significant increase in tumour EPA incorporation and lower intra-tumoral PGE(2) levels (with concomitant increased production of PGE(3) ). Liver tumours from 5% EPA-FFA treated mice demonstrated decreased bromodeoxyuridine-positive CRC cell proliferation and reduced phosphorylated extracellular signal-related kinase 1/2 expression at the invasive edge of tumours. A concentration-dependent reduction in MC-26 CRC cell Transwell® migration following EPA-FFA treatment (50-200µM) in vitro was rescued by exogenous PGE(2) (10µM) and PGE(1) -alcohol (1µM). Conclusions:  EPA-FFA inhibits MC-26 CRC cell liver metastasis. EPA incorporation is associated with a 'PGE(2) to PGE(3) switch' in liver tumours. Inhibition of PGE(2) -EP4 receptor-dependent CRC cell motility likely contributes to the anti-neoplastic activity of EPA"

  • (n-3) Fatty Acids and Cardiovascular Health: Are Effects of EPA and DHA Shared or Complementary? - J Nutr. 2012 Jan 25 - "We reviewed evidence for dietary and endogenous sources and cardiovascular effects on biologic pathways, physiologic risk factors, and clinical endpoints of EPA [20:5(n-3)], docosapentaenoic acid [DPA, 22:5(n-3)], and DHA [22:6(n-3)]. DHA requires direct dietary consumption, with little synthesis from or retroconversion to DPA or EPA. Whereas EPA is also largely derived from direct consumption, EPA can also be synthesized in small amounts from plant (n-3) precursors, especially stearidonic acid. In contrast, DPA appears principally derived from endogenous elongation from EPA, and DPA can also undergo retroconversion back to EPA. In experimental and animal models, both EPA and DHA modulate several relevant biologic pathways, with evidence for some differential benefits. In humans, both fatty acids lower TG levels and, based on more limited studies, favorably affect cardiac diastolic filling, arterial compliance, and some metrics of inflammation and oxidative stress. All three (n-3) PUFA reduce ex vivo platelet aggregation and DHA also modestly increases LDL and HDL particle size; the clinical relevance of such findings is uncertain. Combined EPA+DHA or DPA+DHA levels are associated with lower risk of fatal cardiac events and DHA with lower risk of atrial fibrillation, suggesting direct or indirect benefits of DHA for cardiac arrhythmias (although not excluding similar benefits of EPA or DPA). Conversely, EPA and DPA, but not DHA, are associated with lower risk of nonfatal cardiovascular endpoints in some studies, and purified EPA reduced risk of nonfatal coronary syndromes in one large clinical trial. Overall, for many cardiovascular pathways and outcomes, identified studies of individual (n-3) PUFA were relatively limited, especially for DPA. Nonetheless, the present evidence suggests that EPA and DHA have both shared and complementary benefits. Based on current evidence, increasing consumption of either would be advantageous compared to little or no consumption. Focusing on their combined consumption remains most prudent given the potential for complementary effects and the existing more robust literature on cardiovascular benefits of their combined consumption as fish or fish oil for cardiovascular benefits"

  • Associations between n-3 PUFA concentrations and cognitive function after recovery from late-life depression - Am J Clin Nutr. 2012 Jan 4 - "sample of 132 eligible participants who had recovered from major depression (mean +/- SD age: 67.8 +/- 6.6 y) were enrolled from outpatient psychiatric services. A series of cognitive tests and a structured questionnaire were administered. Fasting blood samples were collected for n-3 PUFA measurements ... the strongest and most consistent correlations were found between immediate recall and concentrations of total n-3 PUFAs and α-linolenic acid (ALA) in erythrocytes, which were observed only in participants with recurrent depression ... Total erythrocyte n-3 PUFA concentrations are positively associated with cognitive function, particularly immediate recall, in older people with previous depression. Lower concentrations of n-3 PUFAs or ALA in erythrocyte membranes may be good predictors for cognitive impairment in older people with previous recurrent depression"
  • ω-3 and ω-6 polyunsaturated fatty acid intakes and the risk of breast cancer in Mexican women: impact of obesity status - Cancer Epidemiol Biomarkers Prev. 2011 Dec 22 - "Overall, there was no significant association between ω-3 PUFA intake and breast cancer risk (p=0.31). An increased risk of breast cancer was associated with increasing ω-6 PUFA intake in pre-menopausal women (OR=1.92, 95% CI=1.13;3.26; p=0.04). A decreased risk of breast cancer was significantly associated with increasing ω-3 PUFA intake in obese women (OR=0.58, 95%CI=0.39;0.87; p=0.008), but not in normoweight nor in overweight women (p for heterogeneity = 0.017)

  • Hypothalamic gene expression in ω-3 PUFA-deficient male rats before, and following, development of hypertension - Hypertens Res. 2011 Nov 10 - "Dietary deficiency of ω-3 fatty acids (ω-3 DEF) produces hypertension in later life ... Animals were fed experimental diets that were deficient in ω-3 fatty acids, sufficient in short-chain ω-3 fatty acids or sufficient in short- and long-chain ω-3 fatty acids, from the prenatal period until 10 or 36 weeks-of-age. There was no difference in blood pressure between groups at 10 weeks-of-age; however, at 36 weeks-of-age ω-3 DEF animals were hypertensive in relation to sufficient groups. At 10 weeks, expression of angiotensin-II(1A) receptors and dopamine D(3) receptors were significantly increased in the hypothalamic tissue of ω-3 DEF animals. In contrast, at 36 weeks, α(2a) and β(1) adrenergic receptor expression was significantly reduced in the ω-3 DEF group. Brain docosahexaenoic acid was significantly lower in ω-3 DEF group compared with sufficient groups. This study demonstrates that dietary ω-3 DEF causes changes both in the expression of key genes involved in central blood pressure regulation and in blood pressure. The data may indicate that hypertension resulting from ω-3 DEF is mediated by the central adrenergic system"
  • Enteral n-3 fatty acids and micronutrients enhance percentage of positive neutrophil and lymphocyte adhesion molecules: a potential mediator of pressure ulcer healing in critically ill patients - Br J Nutr. 2011 Nov 1:1-6 - "n-3 Fatty acids are recognised as influencing both wound healing and immunity. We assessed the impact of a fish oil- and micronutrient-enriched formula (study formula) on the healing of pressure ulcers and on immune function in critically ill patients in an intensive care unit ... intervention group, n 20, received study formula; and a control group, n 20, received an isoenergetic formula ... Patients who received the study formula showed significant increases in the percentage of positive CD18 and CD11a lymphocytes and of CD49b granulocytes as compared to controls (P < 0.05). While the severity of pressure ulcers was not significantly different between the two groups on admission, severity increased significantly over time for the control group (P < 0.05), but not for the study group. The present study suggests that a fish oil- and micronutrient-enriched formula may prevent worsening of pressure ulcers and that this effect may be mediated by an effect on adhesion molecule expression"
  • Do long-chain n-3 fatty acids reduce arterial stiffness? A meta-analysis of randomised controlled trials - Br J Nutr. 2011 Oct;106(7):974-80 - "A total of ten n-3 trials met the final inclusion criteria; four using pulse wave velocity (PWV) and six using arterial compliance, measured as capacitive compliance or systemic arterial compliance, as respective outcome measures. Meta-analysis revealed that n-3 was statistically significant in effectively improving both PWV (g = 0.33; 95 % CI 0.12, 0.56; P < 0.01) and arterial compliance (g = 0.48; 95 % CI 0.24, 0.72; P < 0.001). There was no evidence of heterogeneity or publication bias. Results were not influenced by changes in blood pressure, heart rate or BMI. The findings of the present study reveal that supplementation with n-3 offers a scientifically supported means of reducing arterial stiffness. Reduction in arterial stiffness by n-3 may account for some of its purported cardioprotective effects" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

  • Effects of n-3 fatty acids, EPA v. DHA, on depressive symptoms, quality of life, memory and executive function in older adults with mild cognitive impairment: a 6-month randomised controlled trial - Br J Nutr. 2011 Sep 20:1-12 - "Depressive symptoms may increase the risk of progressing from mild cognitive impairment (MCI) to dementia. Consumption of n-3 PUFA may alleviate both cognitive decline and depression ... A total of fifty people aged >65 years with MCI were allocated to receive a supplement rich in EPA (1.67 g EPA+0.16 g DHA/d; n 17), DHA (1.55 g DHA+0.40 g EPA/d; n 18) or the n-6 PUFA linoleic acid (LA; 2.2 g/d; n 15). Treatment allocation was by minimisation based on age, sex and depressive symptoms (Geriatric Depression Scale, GDS). Physiological and cognitive assessments, questionnaires and fatty acid composition of erythrocytes were obtained at baseline and 6 months (completers: n 40; EPA n 13, DHA n 16, LA n 11). Compared with the LA group, GDS scores improved in the EPA (P = 0.04) and DHA (P = 0.01) groups and verbal fluency (Initial Letter Fluency) in the DHA group (P = 0.04). Improved GDS scores were correlated with increased DHA plus EPA (r 0.39, P = 0.02). Improved self-reported physical health was associated with increased DHA. There were no treatment effects on other cognitive or QOL parameters. Increased intakes of DHA and EPA benefited mental health in older people with MCI. Increasing n-3 PUFA intakes may reduce depressive symptoms and the risk of progressing to dementia. This needs to be investigated in larger, depressed samples with MCI"

  • Dietary {alpha}-linolenic acid, linoleic acid, and n-3 long-chain PUFA and risk of ischemic heart disease - Am J Clin Nutr. 2011 Aug 24 - "α-linolenic acid (ALA, 18:3n-3)  ... Four hundred seventy-one cases of IHD were observed during a median follow-up period of 23.3 y. Higher intake of ALA was not significantly associated with decreased risk of IHD among women or men. Although the HR of IHD was stepwise decreased with increasing ALA intake in men [0.84 (95% CI: 0.62, 1.14) in the medium compared with the lowest tertile (reference) and 0.83 (95% CI: 0.56, 1.24) in the highest compared with the lowest tertile], this change was far from significant (P-trend: 0.39). No evidence of effect modification by n-3 LC-PUFA or LA was observed. High n-3 LC-PUFA intake, in comparison with low intake, was inversely associated with risk of IHD; this trend was significant in women (P = 0.04; HR: 0.62; 95% CI: 0.40, 0.97) but not in men (P = 0.15; HR: 0.74; 95% CI: 0.51, 1.06). No associations were observed between intake of LA and risk of IHD" - Note:  α-linolenic acid (ALA, 18:3n-3) is the form of omega-3 found in things like vegetable and flax seeds, linoleic acid (LA, 18:2 n-6) is what's in most vegetable oils like corn and soy.
