Recent Longevity News for the seven days ending 2/13/13.  You should consult your doctor if you are taking any medications.

Thin Asians at Risk for Diabetes Due to Hidden Body Fat - Medscape, 2/11/13 - "Japanese American women are twice as likely to be diagnosed with diabetes as whites, despite having lower body-mass indexes (BMIs) ... Indians are often diagnosed with diabetes 10 years earlier and 5- to 10-units BMI thinner than whites ... Both believe the explanation lies in "hidden" visceral fat found inside the body, between organs, in Asians and probably other ethnic groups too, but not in whites. This in turn affects the levels of adipokines secreted, such as leptin and adiponectin, which can have adverse metabolic effects ... Overall, Japanese women had significantly lower BMIs (23.7 vs 25.3 kg/m2), leptin (15.0 vs 25.9 ng/mL), and adiponectin (11.7 vs 16.0 µg/mL) than whites ... one factor he believes may be playing an important role in India is vegetarianism. People there consume high amounts of folate but are deficient in vitamin B12, creating a low-B12/high-folate intrauterine environment that "produces babies who are mostly insulin resistant."" - See my adiponectin page for ways to increase it.  The way I understand it, leptin just decreases appetite.  If a person is already thin I wouldn't think it would affect visceral fat.

Exercise linked with reduced prostate cancer risk in Caucasians but not African-Americans - Science Daily, 2/11/13 - "Lionel L. Bañez, MD, of the Durham Veterans Affairs Medical Center, and his colleagues asked 307 men (164 white; 143 black) undergoing a prostate biopsy to complete a survey that assessed their exercise amounts per week ... Among Caucasians, men who were moderately or highly active were 53% less likely to have biopsy results indicating that they had prostate cancer compared with men who were sedentary or mildly active ... Among men with cancer, those who exercised had a 13% reduced risk of having high grade disease"

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" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

CKD and Low Magnesium: Pay Attention - Medscape, 2/6/13 - "When adjusted for differences in age and sex among quartiles, the lowest magnesium group had the highest incidence of new atrial fibrillation events (9.4 episodes per 1000 person-years). The rates for the other 3 quartiles were quite similar (6.9, 7.1, and 6.3 events per 1000 person-years for the second, third, and fourth quartiles, respectively). In multivariable models controlled for the multiple potential differences including glomerular filtration rate, those with the lowest levels of magnesium continued to be at highest risk for the development of atrial fibrillation (hazard ratio, 1.48; 95% confidence interval, 1.02- 2.14; P = .04)" - See magnesium supplements at Amazon.com.

Smoking marijuana associated with higher stroke risk in young adults - Science Daily, 2/6/13 - "In a New Zealand study, ischemic stroke and transient ischemic attack (TIA) patients were 2.3 times more likely to have cannabis, also known as marijuana, detected in urine tests as other age and sex matched patients ... People need to think twice about using cannabis," because it can affect brain development and result in emphysema, heart attack and now stroke"

Re-Analysis Refutes Diet Guidelines Favoring Vegetable Fats - WebMD, 2/6/13 - "The first group was told to consume linoleic acid, in the form of safflower oil and safflower oil polyunsaturated margarine, at levels equal to 15 percent of total calorie intake. This, said Ramsden, is equivalent to roughly twice the amount that Americans currently consume ... While omega-3 consumption was not affected, the men were also asked to lower their saturated fat intake so that it made up less than 10 percent of their diets. They did so by substituting safflower oil for animal fats ... The second group continued their routine nutritional habits ... By newly crunching all the original data the NIH team found that, compared to the no-dietary-change group, the linoleic acid group faced a higher risk of death, from both heart disease specifically as well as from all causes overall ... the NIH team found no evidence to support the notion that linoleic acid confers health benefits. The review highlighted the possibility that boosting omega-6 consumption may actually increase the risk for developing heart disease ... Polyunsaturates are not just involved in cholesterol-lowering. They may also be involved in inflammation, oxidation or clotting"

Twenty Hours of TV a Week Linked to Almost Half Sperm Count of Those Who Watch Little TV - Science Daily, 2/5/13 - "Healthy young men who watch TV for more than 20 hours a week have almost half the sperm count of men who watch very little TV ... Conversely, men who do 15 or more hours of moderate to vigorous exercise every week have sperm counts that are 73% higher than those who exercise little ... light physical exercise made no difference to the sperm count, no matter how frequent it was"

Green tea and red wine extracts interrupt Alzheimer's disease pathway in cells - Science Daily, 2/5/13 - "They were able to interrupt this pathway using the purified extracts of EGCG from green tea and resveratrol from red wine ... Alzheimer's disease is characterised by a distinct build-up of amyloid protein in the brain, which clumps together to form toxic, sticky balls of varying shapes. These amyloid balls latch on to the surface of nerve cells in the brain by attaching to proteins on the cell surface called prions, causing the nerve cells to malfunction and eventually die ... The team formed amyloid balls in a test tube and added them to human and animal brain cells ... When we added the extracts from red wine and green tea, which recent research has shown to re-shape amyloid proteins, the amyloid balls no longer harmed the nerve cells" - See green tea extract at Amazon.com and resveratrol products at Amazon.com.

Vitamin D, omega-3 may help clear amyloid plaques found in Alzheimer's - Science Daily, 2/5/13 - "Our new study sheds further light on a possible role for nutritional substances such as vitamin D3 and omega-3 in boosting immunity to help fight Alzheimer's ... The team incubated the immune cells overnight with amyloid-beta. They added either an active form of vitamin D3 called 1alpha,25–dihydroxyvitamin D3 or an active form of the omega-3 fatty acid DHA called resolvin D1 to some of the cells to gauge the effect they had on inflammation and amyloid-beta absorption ... Both 1alpha, 25-dihydroxyvitamin D3 and resolvin D1 improved the ability of the Alzheimer's disease patients' macrophages to gobble-up amyloid-beta, and they inhibited the cell death that is induced by amyloid-beta. Researchers observed that each nutrition molecule utilized different receptors and common signaling pathways to do this"

 Some omega-3 oils better than others for protection against liver disease - Science Daily, 2/5/13 - "EPA had comparatively little effect on preventing the fibrosis, or scarring, that's associated with NASH. However, DHA supplementation reduced the proteins involved in liver fibrosis by more than 65 percent ... A reduction of that magnitude in the actual scarring and damage to the liver is very important ... DHA was more effective than EPA at attenuating inflammation, oxidative stress, fibrosis and hepatic damage" -  Note:  I take both.  See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

It actually is better (and healthier) to give than to receive, study finds - Science Daily, 2/4/13 - "when dealing with stressful situations, those who had helped others during the previous year were less likely to die than those who had not helped others ... Self-reported stressful experiences included such things as serious, non-life-threating illness, burglary, job loss, financial difficulties or death of a family member ... Respondents also reported the total amount of time in the past 12 months they had spent helping friends, neighbors or relatives who did not live with them by providing transportation, doing errands and shopping, performing housework, providing child care and other tasks ... the Cox proportional hazard models (the most widely used method of survival analysis) for mortality revealed a significant interaction between helping behavior, stressful events, morbidity and mortality"

Decreased Serum Concentrations of 25-Hydroxycholecalciferol Are Associated With Increased Risk of Progression to Impaired Fasting Glucose and Diabetes - Diabetes Care. 2013 Feb 7 - "In a historical prospective cohort study of subjects from the Clalit Health Services database, which includes information on nearly 4 million people, diabetes-free subjects aged 40-70 years with serum 25-hydroxyvitamin D (25-OHD) measurements available were followed up for 2 years to assess the development of IFG and diabetes in five 25-OHD subgroups: ≥25, 25.1-37.5, 37.6-50, 50.1-75, and >75 nmol/L ... The odds of transitioning from normoglycemia to IFG, from normoglycemia to diabetes, and from IFG to diabetes in subjects with a 25-OHD level ≤25 nmol/L were greater than those of subjects with a 25-OHD level >75 nmol/L [odds ratio 1.13 (95% CI 1.03-1.24), 1.77 (1.11-2.83), and 1.43 (1.16-1.76), respectively] ... Vitamin D deficiency appears to be an independent risk factor for the development of IFG and diabetes" - See vitamin D at Amazon.com.

U-Shape Association Between Hemoglobin A1c and Late Mortality in Patients With Heart Failure After Cardiac Surgery - Am J Cardiol. 2013 Feb 4 - "Patients with and without New York Heart Association class III or IV heart failure were divided into quartiles according to the preoperative HbA1c level ... After adjusting for confounders, the patients without heart failure and with HbA1c ≤5.7% had the lowest risk of death. In patients with preoperative heart failure, we found a U-shaped association between HbA1c levels and late mortality, with those patients with HbA1c levels of 5.8% to 6.2% having the lowest risk of death. HbA1c levels ≤5.7% and ≥7.2% were associated with statistically significant greater risks of death"

Serum Folate but Not Vitamin B-12 Concentrations Are Positively Associated with Cognitive Test Scores in Children Aged 6-16 Years - J Nutr. 2013 Feb 6 - "Serum folate and vitamin B-12 concentrations were measured, along with performance, on the Wide Range Achievement Test-Revised and the Wechsler Intelligence Scale for Children-Revised ... serum concentrations of folate were associated with higher reading and block design scores after adjusting for various covariates. For example, compared with the lowest quartile of folate, children in the highest quartile scored 3.28 points or 0.19 SD units higher on the reading test (P < 0.05). Vitamin B-12 was not associated with any of the test scores. In the largest study to date, higher folate concentrations were associated with better reading and block design scores" - See folic acid products at Amazon.com.

Soy isoflavone intake and breast cancer risk in Japan: From the takayama study - Int J Cancer. 2013 Feb 6 - "We assessed the associations of soy and isoflavone intake with breast cancer incidence in a population-based prospective cohort study in Japan. Participants were members from the Takayama study, aged 35 years or older in 1992 ... Soy and isoflavone intakes were assessed with a validated food-frequency questionnaire ... The relative risks of postmenopausal breast cancer were lower among women with higher intakes of soy (trend p=0.023) and isoflavone (trend p=0.046), although the relative risks of premenopausal breast cancer were not associated with intakes of soy and isoflavone. Decreased risks of breast cancer were found even among women with a moderate intake of soy and isoflavone. These results suggested that soy and isoflavone intake have a protective effect on postmenopausal breast cancer"

Post-exercise whey protein hydrolysate supplementation induces a greater increase in muscle protein synthesis than its constituent amino acid content - Br J Nutr. 2013 Feb 7:1-7 - "Male Sprague-Dawley rats swam for 2 h to depress muscle protein synthesis. Immediately after exercise, the animals were administered either carbohydrate (CHO), CHO plus an amino acid mixture (AA) or CHO plus WPH. At 1 h after exercise, the supplements containing whey-based protein (AA and WPH) caused a significant increase in the fractional rate of protein synthesis (FSR) compared with CHO ... These results indicate that WPH may include active components that are superior to amino acids for stimulating muscle protein synthesis and initiating translation" - See whey protein at Amazon.com.

Fish oil supplementation reduces cortisol basal levels and perceived stress: A randomized, placebo-controlled trial in abstinent alcoholics - Mol Nutr Food Res. 2013 Feb 6 - "Behavioral distress and dysfunctions of hypothalamic-pituitary-adrenocortical (HPA) axis play a central role in alcohol abuse. Omega-3 fatty acids are proposed as having antistress, regulatory effects on HPA responsiveness ... doubleblind, placebo-controlled trial was performed in male alcoholics undergoing residential rehabilitation program, to evaluate the effects of 3-week supplementation with fish-oil providing eicosapentaenoic (60 mg/day) and docosahexaenoic acid (252 mg/day) on perceived stress/anxiety and HPA activity, assessed by measuring saliva basal cortisol levels at various daytimes ... In conclusion, an elevated omega-3 intake may reduce distress symptoms and basal cortisol secretion in abstinent alcoholics, thus providing a valid subsidiary measure to increase the efficacy of rehabilitation programs in ethanol addicts" - Note:  I'm wondering why they chose such a low dose.  That's not even the amount of omega-3 in the average capsule on one good fish oil capsule.  See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Alleviation of chronic pain following rat spinal cord compression injury with multimodal actions of huperzine A - Proc Natl Acad Sci U S A. 2013 Feb - "Compared with controls, HUP-A treatment demonstrates significant analgesic effects in both regimens. SCI rats manifested no drug tolerance following repeated bolus i.p. or chronic intrathecal HUP-A dosing. The pain-ameliorating effect of HUP-A is cholinergic dependent. Relative to vehicle treatment, HUP-A administration also reduced neural inflammation, retained higher numbers of calcium-impermeable GluR2-containing AMPA receptors, and prevented Homer1a up-regulation in dorsal horn sensory neurons. Therefore, HUP-A may provide safe and effective management for chronic postneurotrauma pain by reestablishing homeostasis of sensory circuits" - See huperzine products at iHerb.

Folate deficiency is associated with oxidative stress, increased blood pressure, and insulin resistance in spontaneously hypertensive rats - Am J Hypertens. 2013 Jan;26(1):135-40 - "we analyzed the role of folate deficiency in pathogenesis of the metabolic syndrome in the spontaneously hypertensive rat (SHR) ... Folate deficiency also increased systolic blood pressure by approximately 15mm Hg ... These findings demonstrate that the SHR model is susceptible to the adverse metabolic and hemodynamic effects of low dietary intake of folate. The results are consistent with the hypothesis that folate deficiency can promote oxidative stress and multiple features of the metabolic syndrome that are associated with increased risk for diabetes and cardiovascular disease" - See folic acid products at Amazon.com.

Plasma total testosterone and incident cardiovascular events in hypertensive patients - Am J Hypertens. 2013 Mar;26(3):373-81 - "Hypertension, a major contributory factor to the development of cardiovascular disease, has also been associated with increased prevalence of low testosterone. We investigated whether low androgen concentration predicts incident major adverse cardiovascular events (MACE) in middle-aged nondiabetic hypertensive patients without clinical atherosclerosis ... total testosterone (TT) ... Compared to patients who did not experience MACE, hypertensive subjects who developed MACE had lower TT concentration (3.9+/-0.7ng/ml vs. 4.6+/-1.5ng/ml, P < 0.01) and a higher prevalence of hypogonadism (36% vs. 16%, P < 0.05). Subjects in the lowest TT tertile (<4.0ng/ml) had a statistically significant higher risk of MACE compared to those in the highest tertile (>4.9ng/ml) in multivariate Cox models adjusted for age, systolic blood pressure, and risk factors (all P < 0.05). A TT plasma level of 5.04ng/ml was associated with a negative predictive value (ability to "rule out" MACE) of 97.2%. Addition of TT to standard risk factors model yielded a net reclassification improvement of 38.8 % (P < 0.05)"

Health Focus (Dangers of Fructose):

News & Research:

  • Fructose has different effect than glucose on brain regions that regulate appetite - Science Daily, 1/1/13 - "ingestion of glucose but not fructose reduced cerebral blood flow and activity in brain regions that regulate appetite, and ingestion of glucose but not fructose produced increased ratings of satiety and fullness"
  • Weekly soft drink consumption bubbles up knee osteoarthritis; especially in men - Science Daily, 11/11/12 - "men who consumed more soft drinks per week had worse knee OA progression. The joint space became narrower by an average of 0.29 millimeters in men who drank no soft drinks to 0.59 millimeters in men who drank more than five soft drinks a week. Interestingly, men with lower BMI, less than 27.5 kg/m2, showed more knee OA progression with increased soft-drink consumption than men who had higher BMI scores. By contrast, only women in the lowest BMI segment of the study, less than 27.3kg/m2, showed an association between more soft-drink consumption and knee OA progression"
  • Eating lots of carbs, sugar may raise risk of cognitive impairment - Science Daily, 10/16/12 - "People 70 and older who eat food high in carbohydrates have nearly four times the risk of developing mild cognitive impairment, and the danger also rises with a diet heavy in sugar, Mayo Clinic researchers have found. Those who consume a lot of protein and fat relative to carbohydrates are less likely to become cognitively impaired ... Researchers tracked 1,230 people ages 70 to 89 who provided information on what they ate during the previous year ... A high carbohydrate intake could be bad for you because carbohydrates impact your glucose and insulin metabolism"
  • Increased dietary fructose linked to elevated uric acid levels and lower liver energy stores - Science Daily, 9/13/12 - "increased dietary fructose can alter the body's metabolism and energy balance. Energy depletion in the liver may be associated with liver injury in patients with non-alcoholic fatty liver disease (NAFLD) and in those at risk for developing this metabolic condition ... For the present study, 244 obese and diabetic adults from the Look AHEAD Study were evaluated, with dietary fructose consumption estimated by the food frequency questionnaire ... "High fructose consumption and elevated levels of uric acid are associated with more severe depletion of liver ATP. Our findings suggest that increased dietary fructose intake may impair liver "energy balance." Further research to define the clinical implications of these findings on metabolism and NAFLD is necessary.""
  • New evidence in fructose debate: Could it be healthy for us? - Science Daily, 6/21/12 - "fructose may not be as bad for us as previously thought and that it may even provide some benefit ... this research suggests that the problem is likely one of overconsumption, not fructose ... The study reviewed 18 trials with 209 participants who had Type 1 and 2 diabetes and found fructose significantly improved their blood sugar control. The improvement was equivalent to what can be achieved with an oral antidiabetic drug ... We're seeing that there may be benefit if fructose wasn't being consumed in such large amounts ... All negative attention on fructose-related harm draws further away from the issue of eating too many calories" - [Abstract]
  • This is your brain on sugar: Study in rats shows high-fructose diet sabotages learning, memory - Science Daily, 5/15/12 - "Binging on soda and sweets for as little as six weeks may make you stupid ... Eating a high-fructose diet over the long term alters your brain's ability to learn and remember information. But adding omega-3 fatty acids to your meals can help minimize the damage ... studied two groups of rats that each consumed a fructose solution as drinking water for six weeks. The second group also received omega-3 fatty acids in the form of flaxseed oil and docosahexaenoic acid (DHA), which protects against damage to the synapses -- the chemical connections between brain cells that enable memory and learning ... DHA is essential for synaptic function -- brain cells' ability to transmit signals to one another ... Our findings suggest that consuming DHA regularly protects the brain against fructose's harmful effects" - See Jarrow Max DHA at Amazon.com.
  • Soda consumption increases overall stroke risk - Science Daily, 4/20/12 - "The research analyzed soda consumption among 43,371 men who participated in the Health Professionals Follow-Up Study between 1986 and 2008, and 84,085 women who participated in the Nurses' Health Study between 1980 and 2008 ... In sugar-sweetened sodas, the sugar load may lead to rapid increases in blood glucose and insulin which, over time, may lead to glucose intolerance, insulin resistance, and inflammation. These physiologic changes influence atherosclerosis, plaque stability and thrombosis -- all of which are risk factors of ischemic stroke ... In comparison, coffee contains chlorogenic acids, lignans and magnesium, all of which act as antioxidants and may reduce stroke risk. When compared with one serving of sugar-sweetened soda, one serving of decaffeinated coffee was associated with a 10 percent lower risk of stroke"
  • Sugar-sweetened drinks linked to increased risk of heart disease in men - Science Daily, 3/1/12 - "Men who drank a 12-ounce sugar-sweetened beverage a day had a 20 percent higher risk of heart disease compared to men who didn't drink any sugar-sweetened drinks"
  • Research offers insight to how fructose causes obesity and other illness - Science Daily, 2/27/12
  • High fizzy soft drink consumption linked to violence among teens - Science Daily, 10/25/11 - "heavy use of carbonated non-diet soft drinks was significantly associated with carrying a gun or knife, and violence towards peers, family members and partners ... When the findings were divided into four categories of consumption, the results showed a clear dose-response relationship across all four measures ... There may be a direct cause-and-effect-relationship, perhaps due to the sugar or caffeine content of soft drinks, or there may be other factors, unaccounted for in our analyses, that cause both high soft drink consumption and aggression"
  • Dietary Fructose and Risk of Metabolic Syndrome in Adults - Medscape, 9/28/11 - "in our study the association between dietary fructose and metabolic syndrome and its components was observed only in the third and fourth quartiles of fructose intakes, approximately over 8 and 12% of energy intake (> 50 g/d); while dietary intake of fructose from natural sources including fruits and vegetables, even in the fourth quartile of fructose intakes was only 5% of energy, approximately 30 g/d. Thus, the increased risk of metabolic syndrome and its components may be attributed to increase fructose intake from industrialized foods"
  • Sugar-sweetened drinks associated with higher blood pressure - Science Daily, 3/1/11 - "for every extra sugar-sweetened beverage drunk per day participants on average had significantly higher systolic blood pressure by 1.6 millimeters of mercury (mm Hg) and diastolic blood pressure higher by 0.8 mm Hg ... They found no consistent association between diet soda intake and blood pressure levels. Those who drank diet soda had higher mean BMI than those who did not and lower levels of physical activity ... One possible mechanism for sugar-sweetened beverages and fructose increasing blood pressure levels is a resultant increase in the level of uric acid in the blood that may in turn lower the nitric oxide required to keep the blood vessels dilated. Sugar consumption also has been linked to enhanced sympathetic nervous system activity and sodium retention"
  • Highest Mortality Risk Seen With High-Fat Dairy and High Sugar Intake - Medscape, 12/23/10 - "Compared to people who ate healthy foods, men and women in their 70s had a 40% higher risk of death if they got most of their calories from high-fat dairy foods or from sweets and desserts" - I'd take that one study with a grain of salt.  In regard to dairy, it contradicts this analysis of many studies.
    • Milk and dairy consumption and incidence of cardiovascular diseases and all-cause mortality: dose-response meta-analysis of prospective cohort studies - Am J Clin Nutr. 2011 Jan;93(1):158-71 - "PubMed, EMBASE, and SCOPUS were searched for articles published up to February 2010. Of >5000 titles evaluated, 17 met the inclusion criteria, all of which were original prospective cohort studies ... A modest inverse association was found between milk intake and risk of overall CVD [4 studies; relative risk (RR): 0.94 per 200 mL/d; 95% CI: 0.89, 0.99]. Milk intake was not associated with risk of CHD (6 studies; RR: 1.00; 95% CI: 0.96, 1.04), stroke (6 studies; RR: 0.87; 95% CI: 0.72, 1.05), or total mortality (8 studies; RR per 200 mL/d: 0.99; 95% CI: 0.95, 1.03). Limited studies of the association of total dairy products and of total high-fat and total low-fat dairy products (per 200 g/d) with CHD showed no significant associations"
  • Excess fructose may play role in diabetes, obesity and other health conditions - Science Daily, 11/22/10 - "The link between excessive intake of fructose and metabolic syndrome is becoming increasingly established. However, in this review of the literature, the authors conclude that there is also increasing evidence that fructose may play a role in hypertension and renal disease. "Science shows us there is a potentially negative impact of excessive amounts of sugar and high fructose corn syrup on cardiovascular and kidney health," explains Dr. Johnson. He continues that "excessive fructose intake could be viewed as an increasingly risky food and beverage additive.""
  • Fructose-rich beverages associated with increased risk of gout in women - Science Daily, 11/10/10 - "Compared with consumption of less than 1 serving per month, women who consumed one serving per day had a 74 percent increased risk of gout; and those with 2 or more servings per day had a 2.4 times higher risk ... Orange juice intake was also associated with risk of gout. Compared with women who consumed less than a glass (6 oz.) of orange juice per month, women who consumed 1 serving per day had a 41 percent higher risk of gout, and there was a 2.4 times higher risk with 2 or more servings per day"
  • Pancreatic cancers use fructose, common in the Western diet, to fuel their growth - Science Daily, 8/2/10 - "The bottom line is the modern diet contains a lot of refined sugar including fructose and it's a hidden danger implicated in a lot of modern diseases, such as obesity, diabetes and fatty liver ... the pancreatic cancer cells could easily distinguish between glucose and fructose even though they are very similar structurally, and contrary to conventional wisdom, the cancer cells metabolized the sugars in very different ways. In the case of fructose, the pancreatic cancer cells used the sugar in the transketolase-driven non-oxidative pentose phosphate pathway to generate nucleic acids, the building blocks of RNA and DNA, which the cancer cells need to divide and proliferate"
  • High fructose diet may contribute to high blood pressure, study finds - Science Daily, 7/1/10 - "people who consumed a diet of 74 grams or more per day of fructose (corresponding to 2.5 sugary soft drinks per day) had a 26%, 30%, and 77% higher risk for blood pressure levels of 135/85, 140/90, and 160/100 mmHg, respectively. (A normal blood pressure reading is below 120/80 mmHg.)"
  • High fructose, trans fats lead to significant liver disease, says study - Science Daily, 6/22/10 - "mice fed the normal calorie chow diet remained lean and did not have fatty liver disease. Mice fed high calorie diets (trans-fat alone or a combination of trans-fat and high fructose) became obese and had fatty liver disease ... it was only the group fed the combination of trans-fat and high fructose which developed the advanced fatty liver disease which had fibrosis ... This same group also had increased oxidative stress in the liver, increased inflammatory cells, and increased levels of plasma oxidative stress markers"
  • Fructose sugar makes maturing human fat cells fatter, less insulin-sensitive, study finds - Science Daily, 6/21/10 - "high levels of fructose, which may result from eating a diet high in fructose, throughout childhood may lead to an increase in visceral [abdominal] obesity, which is associated with increased cardiometabolic risk ... For both types of fat cells, maturation in fructose decreased the cells' insulin sensitivity, which is the ability to successfully take up glucose from the bloodstream into fat and muscles. Decreased insulin sensitivity is a characteristic of Type 2 diabetes"
  • Drinking fewer sugar-sweetened beverages may lower blood pressure - Science Daily, 5/24/10 - ""Our findings suggest that reducing sugar-sweetened beverages and sugar consumption may be an important dietary strategy to lower blood pressure and further reduce other blood pressure-related diseases," Chen said. "It has been estimated that a 3-millimeters of mercury (mm Hg) reduction in systolic blood pressure should reduce stroke mortality by 8 percent and coronary heart disease mortality by 5 percent. Such reductions in systolic blood pressure would be anticipated by reducing sugar-sweetened beverages consumption by an average of 2 servings per day ... a reduction of one serving/day of SSB was associated with a 1.8 millimeters of mercury (mm Hg) drop in systolic pressure and a 1.1 mm Hg decline in diastolic pressure over 18 months"
  • Study: Too Much Sugar Increases Heart Risks - Time Magazine, 4/21/10 - "Compared with people consuming less than 5% of their daily calories in added sugar, those in the highest consumption group — who got 25% or more of their daily calories in added sugar — were twice as likely to have low levels of HDL cholesterol, the beneficial lipid that mops up artery-clogging LDL cholesterol. According to government health guidelines, HDL levels below 50 mg/dL for women and 40 mg/dL for men are considered low; 43% of the highest sugar consumers recorded low HDL, while only 22% of the lowest sugar consumers did ... People eating the most added sugar also recorded the highest triglyceride levels ... Low HDL and high triglyceride levels are two of the primary risk factors for heart disease"
  • High fructose corn syrup linked to liver scarring, research suggests - Science Daily, 3/22/10 - "The researchers found only 19 percent of adults with NAFLD reported no intake of fructose-containing beverages, while 52 percent consumed between one and six servings a week and 29 percent consumed fructose-containing beverages on a daily basis"
  • High-fructose corn syrup prompts considerably more weight gain, researchers find - Science Daily, 3/22/10
  • Drinking sugar-sweetened beverages daily linked to diabetes - Science Daily, 3/6/10 - "Using the Coronary Heart Disease (CHD) Policy Model, a well-established computer simulation model of the national population age 35 and older, researchers estimate that the increased consumption of sugar-sweetened beverages between 1990 and 2000 contributed to 130,000 new cases of diabetes, 14,000 new cases of coronary heart disease (CHD), and 50,000 additional life-years burdened by coronary heart disease over the past decade"
  • Soft drink consumption may markedly increase risk of pancreatic cancer - Science Daily, 2/8/10 - "Consuming two or more soft drinks per week increased the risk of developing pancreatic cancer by nearly twofold compared to individuals who did not consume soft drinks" - [Abstract]
  • High Fructose Intake Linked to Metabolic Syndrome, Kidney Disease - Science Daily, 1/14/10 - "men who were randomized to receive 200 g fructose daily for 2 weeks without or without allopurinol ...

  • Fructose consumption leads to reduced aerobic capacity and to liver injury in rats - Lipids Health Dis. 2012 Jun 19;11(1):78 - "We separated twenty-eight rats into two groups according to diet: a control group (C) (balanced diet) and a fructose group (F) (fed a diet containing fructose as 60% of the total caloric intake) ... The animals fed a fructose-rich diet exhibited a reduction in aerobic capacity, glucose tolerance and insulin sensitivity and increased concentrations of triglycerides and TBARS in the liver. Catalase and SOD activities were reduced in the livers of the fructose-fed animals. In addition, the serum AST/ALT ratio was higher than that of the C group, which indicates hepatic damage, and the damage was confirmed by histology. In conclusion, the fructose-rich diet caused significant liver damage and a reduction in insulin sensitivity in the animals, which could lead to deleterious metabolic effects"

  • "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" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

RRs for consuming more than 15 grams of sucrose/day as compared to 15 grams or less were 1.97 (1.27-3.04) among obese women and 1.56 (1.20-2.04) among women with low fat intake"
  • Habitual sugar intake and cognitive function among middle-aged and older Puerto Ricans without diabetes - Br J Nutr. 2011 Jun 1:1-10 - "Intake of added sugars, mainly fructose and sucrose, has been associated with risk factors for cognitive impairment, such as obesity, the metabolic syndrome and type 2 diabetes. The objective of this analysis was to examine whether habitual intakes of total sugars, added sugars, sugar-sweetened beverages or sweetened solid foods are associated with cognitive function. The present study included 737 participants without diabetes, aged 45-75 years, from the Boston Puerto Rican Health Study, 2004-9. Cognitive function was measured with a battery of seven tests: Mini-Mental State Examination (MMSE), word list learning, digit span, clock drawing, figure copying, and Stroop and verbal fluency tests. Usual dietary intake was assessed with a validated FFQ. Greater intakes of total sugars, added sugars and sugar-sweetened beverages, but not of sugar-sweetened solid foods, were significantly associated with lower MMSE score, after adjusting for covariates. Adjusted OR for cognitive impairment (MMSE score < 24) were 2.23 (95 % CI 1.24, 3.99) for total sugars and 2.28 (95 % CI 1.26, 4.14) for added sugars, comparing the highest with lowest intake quintiles. Greater intake of total sugars was also significantly associated with lower word list learning score. In conclusion, higher sugar intake appears to be associated with lower cognitive function, but longitudinal studies are needed to clarify the direction of causality"

  • Nutrition and aging skin: sugar and glycation - Clin Dermatol. 2010 Jul-Aug;28(4):409-11 - "The effect of sugars on aging skin is governed by the simple act of covalently cross-linking two collagen fibers, which renders both of them incapable of easy repair. Glucose and fructose link the amino acids present in the collagen and elastin that support the dermis, producing advanced glycation end products or "AGEs." This process is accelerated in all body tissues when sugar is elevated and is further stimulated by ultraviolet light in the skin. The effect on vascular, renal, retinal, coronary, and cutaneous tissues is being defined, as are methods of reducing the glycation load through careful diet and use of supplements"
