Recent Longevity News for the seven days ending 7/9/08.  You should consult your doctor if you are taking any medications.

Lowering Blood Cholesterol With Fish Oil And Red Yeast Rice Instead Of Statins - Science Daily, 7/8/08 - "The alternative treatment group participants received daily fish oil and red yeast rice supplements ... The statin group participants received 40 milligrams (mg) of Zocor (simvastatin) daily ... The researchers noted that there was a reduction in LDL cholesterol levels in both groups. The alternative treatment group experienced a 42.4 percent reduction, and the statin group experienced a 39.6 percent reduction. Members of the alternative therapy group also had a substantial reduction in triglycerides, another form of fat found in the blood, and lost more weight" - See red yeast rice at Amazon.com and Mega Twin EPA at Amazon.com.

Prostate Cancer Hormone Therapy: No Survival Benefit in Older Men - WebMD, 7/8/08 - "In the U.S., older men often opt for stand-alone hormone therapy, even though there's no proof that it really helps. Hormone therapy's most obvious side effect is sexual dysfunction. Of greater concern are several recent studies linking androgen deprivation therapies to diabetes, heart disease, bone fractures, and reduced muscle mass ... Now a new study strongly suggests that hormone therapy offers older men no benefit to justify these serious risks" - [Science Daily]

Green Vegetables, Fruit Intake Linked to Lower Risk for Diabetes in Women - Medscape, 7/8/09 - "Women who have a higher intake of green leafy vegetables and fruit have a lower risk for type 2 diabetes, whereas those who have a higher intake of fruit juices may have an increased risk for the disease ... An increase of 3 servings of total fruit and vegetable consumption per day was not linked to the development of diabetes (multivariate-adjusted hazard ratio [HR], 0.99; 95% confidence interval [CI], 0.94 -1.05), However, an increase in whole fruit consumption of 3 servings per day was associated with a lower risk for type 2 diabetes (HR, 0.82 ... An increase of 1 serving per day of green leafy vegetables was linked to a slightly lower hazard of diabetes (HR, 0.91; 95% CI, 0.84 - 0.98). In contrast, an increase of 1 serving per day of fruit juice consumption was associated with an increased risk for diabetes (HR, 1.18"

Resveratrol May Prevent Breast Cancer - WebMD, 7/7/08 - "when the body's system for processing estrogen gets out of balance, dangerous estrogen metabolites appear. These toxic compounds react with DNA in breast cells and jump-start the growth of tumors ... resveratrol decreases the processing of estrogen into these dangerous compounds. Perhaps more importantly, it also blocks interactions between estrogen metabolites and cellular DNA ... And that's not all. Rogan's team finds that resveratrol increases production of an enzyme that destroys dangerous estrogen metabolites" - [Science Daily] - See resveratrol products at Amazon.com.

Vitamin D Deficiency and Chronic Migraine - Medscape, 7/7/08 - "New research showing that vitamin D deficiency is common in patients with chronic migraine suggests that this patient group, like other vitamin D deficient populations, is at increased risk for cardiovascular disease, malignancy, and other serious illnesses that have been linked to low levels of this "good-health" vitamin ... 40.7% of patients with chronic migraine were deficient in 25-hydroxyvitamin D. The study also showed that the longer individuals had chronic migraine, the more likely they were to be vitamin D deficient" - See vitamin D at Amazon.com.

Green tea's heart benefits gain support - Nutra USA, 7/7/08 - "Regular consumption of green tea may improve the function of endothelial cells - cells lining the walls of blood vessels - and boost cardiovascular health, according to new research from Greece" - [Abstract] - See green tea extract at Amazon.com.

Interval Training May Beat Mild Exercise at Taming Metabolic Syndrome - WebMD, 7/7/08 - "aerobic interval training -- in which people push their heart rate almost to its limits briefly, followed by a more moderate pace, several times during a workout -- may be even better at reining in metabolic syndrome"

Schizophrenia Linked To Dysfunction In Molecular Brain Pathway Activated By Marijuana - Science Daily, 7/7/08 - "The use of marijuana in individuals with schizophrenia appears to worsen this deficit in GABA synthesis"

Some Seek Guidelines to Reflect Vitamin D's Benefits - washingtonpost.com, 7/4/0 - "A flurry of recent research indicating that Vitamin D may have a dizzying array of health benefits has reignited an intense debate over whether federal guidelines for the "sunshine vitamin" are outdated, leaving millions unnecessarily vulnerable to cancer, heart disease, diabetes and other ailments"

Vitamin D Status During Pregnancy Affects Baby's Dental Health - Doctor's Guide, 7/3/08 - [Science Daily] - "Low maternal vitamin D levels during pregnancy may affect primary tooth calcification, leading to enamel defects, which are a risk factor for early childhood tooth decay"

Resveratrol, Found In Red Wine, Wards Off Effects Of Age On Heart, Bones, Eyes And Muscle - Science Daily, 7/3/08 - "This study, conducted and supported in part by the National Institute on Aging (NIA), part of the National Institutes of Health, is a follow-up to 2006 findings that resveratrol improves health and longevity of overweight, aged mice. The report confirms previous results suggesting the compound, found naturally in foods like grapes and nuts, may mimic, in mice, some of the effects of dietary or calorie restriction, the most effective and reproducible way found to date to alleviate age-associated disease in mammals" - See resveratrol products at Amazon.com.

Lycopene as effective as statins for artery health: rabbit study - Nutra USA, 7/3/08 - "The results of our experiment in the high-fat diet rabbit model showed that lycopene and fluvastatin lowered serum levels of total cholesterol and LDL-cholesterol, improved lipid metabolism, and reduced the amount of triacylglycerols ... Lycopene intervention reduced the increase in ox-LDL levels in rabbits on the high-fat diet, whereas fluvastatin did not show such an effect. The cause of this difference is at present not known, although the result speaks in favour of lycopene ... These findings provide a theoretical rationale for the use of lycopene as a preventive in atherosclerosis" - [Abstract] - See Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com.

Looking For The Founatain Of Youth? Cut Your Calories, Research Suggests - Science Daily, 7/3/08 - "While scientists do not know how calorie restriction affects the aging process in rodents, one popular hypothesis is that it slows aging by decreasing a thyroid hormone, triiodothyronine (T3), which then slows metabolism and tissue aging" - All the studies I've read seem to support the opposite:

Fountain of youth? Red wine gives up secrets - MSNBC, 7/3/08 - "Most of mice given resveratrol did not live longer than other mice but were far more healthy in several important measures" - See resveratrol products at Amazon.com.

Benefits Of Green Tea In Reducing An Important Risk Factor For Heart Disease - Science Daily, 7/2/08 - [WebMD] - "More evidence for the beneficial effect of green tea on risk factors for heart disease has emerged in a new study. The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory system; endothelial dysfunction is a key event in the progression of atherosclerosis" - See green tea extract at Amazon.com.

Broccoli May Cut Prostate Cancer Risk - WebMD, 7/1/08 - [Science Daily] - "men who regularly ate broccoli showed more changes in gene expression suggestive of a reduced risk of cancer"

Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

The acute effect of green tea consumption on endothelial function in healthy individuals - Eur J Cardiovasc Prev Rehabil. 2008 Jun;15(3):300-5 - "Flow-mediated dilatation (FMD) ... FMD increased significantly with tea (by 3.69%, peak at 30 min, P<0.02), whereas it did not change significantly with caffeine (increase by 1.72%, peak at 30 min, P=NS) ... Green tea consumption has an acute beneficial effect on endothelial function, assessed with FMD of the brachial artery, in healthy individuals. This may be involved in the beneficial effect of tea on cardiovascular risk" - See green tea extract at Amazon.com.

HbA1C, but not serum glycated albumin, is elevated in late pregnancy due to iron deficiency - Diabetes Care. 2008 Jul 3 - "HbA(1C) levels were elevated in late pregnancy due to iron deficiency. Serum GA may offer a better index for monitoring glycemic control in pregnancy"

Effect of irbesartan on erectile function in patients with hypertension and metabolic syndrome - Int J Impot Res. 2008 Jul 3 - "Erectile function increased significantly (P<0.0001) after 6 months of treatment with irbesartan, irrespective of dosage and independent of additional treatment with hydrochlorothiazide. Prevalence of ED declined to 63.7% from 78.5% at baseline, along with a significant increase in orgasmic function (P<0.001) and intercourse satisfaction (P<0.001). Treatment with irbesartan alone, as well as in combination with hydrochlorothiazide is associated with an improvement of sexual desire, frequency of sexual contacts and erectile function in hypertensive patients with the metabolic syndrome. These results suggest a beneficial role of angiotensin receptor antagonists in the treatment of metabolic syndrome, and ED" - Note:  I've been suggesting telmisartan (an ARB) for some time as the first line treatment for hypertension.  See telmisartan at OffshoreRX.

Comparison of lycopene and fluvastatin effects on atherosclerosis induced by a high-fat diet in rabbits - Nutrition. 2008 Jun 26 - "Compared with the control, levels of total cholesterol, total triacylglycerol, low-density lipoprotein cholesterol, malonaldehyde, oxidized low-density lipoprotein, and interleukin-1 were increased and total antioxidant capacity and nitric oxide were decreased in the animals with a high-fat diet (P < 0.05). Intragastric administration of lycopene counteracted the change in these parameters (P < 0.05). In this case, the data showed that lycopene in the used dose was better than the fluvastatin intervention. Morphologic analysis revealed that lycopene and fluvastatin markedly reduced the formation of atherosclerotic plaques in the aorta compared with the situation in rabbits on a high-fat diet alone ... Lycopene, like fluvastatin, significantly attenuated atherogenesis in rabbits fed a high-fat diet" - See Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com.
