Recent Longevity News for the seven days ending 6/9/10.  You should consult your doctor if you are taking any medications.

Getting extra sleep improves the athletic performance of collegiate football players - Science Daily, 6/8/10 - "football players' sprint times improved significantly after seven to eight weeks of sleep extension. Average sprint time in the 20-yard shuttle improved from 4.71 seconds to 4.61 seconds, and the average 40-yard dash time decreased from 4.99 seconds to 4.89 seconds. Daytime sleepiness and fatigue also decreased significantly, while vigor scores significantly improved"

Long sleep duration linked to an increased risk of metabolic syndrome in older adults - Science Daily, 6/8/10 - "participants who reported a habitual daily sleep duration of eight hours or more including naps were 15 percent more likely to have metabolic syndrome"

To burn more fat, don’t eat before workout - MSNBC, 6/3/10 - "cyclists who trained without eating burned significantly more fat than their counterparts who ate ... When you exercise (after fasting), your adrenaline is high and your insulin is low ... That ratio is favorable for your muscles to oxidize (break down) more fatty acids"

Eat less, live longer? - New Scientist, 6/3/10 - "One piece of evidence for this idea comes from studies in fruit flies and rodents. If these animals are fed special diets with less amino acids - the building blocks of proteins - they can eat as many calories as they want and still live longer ... The protein theory is bad news for people on low-carbohydrate weight-loss plans like the Atkins diet. "I'd be wary of diets that put a heavy emphasis on protein," says Piper. "It's hard to see how that could be healthy." Fontana goes one step further, saying that high-protein diets could risk accelerated ageing and cancer ... There may be another reason for vegans to celebrate. Studies on flies and rodents suggest that cutting intake of one particular amino acid, called methionine, lengthens life to a similar degree as calorie restriction. Proteins in meat and other animal products have high levels of methionine, so a vegan diet would score well by that measure, too" - Note: It claims the a higher IGF-1 may accelerate aging. Growth hormone increases IGF-1.

Use of testosterone for 'male menopause' questionable, experts argue - Science Daily, 6/2/10 - "The published evidence is also inconclusive on whether testosterone given to ageing men with low levels of the hormone improves symptoms, such as poor sexual function or depression ... Testosterone treatment also has several unwanted side effects, says DTB. These include a rise in prostate specific antigen (PSA), blockage of the urinary tract, development of prostate cancer and the development of breasts (gynaecomastia). And it can aggravate ischaemic heart disease, epilepsy, and sleep apnoea"

New evidence that chili pepper ingredient fights fat - Science Daily, 6/2/10 - "The capsaicin-treated rats lost 8 percent of their body weight and showed changes in levels of at least 20 key proteins found in fat. The altered proteins work to break down fats. "These changes provide valuable new molecular insights into the mechanism of the antiobesity effects of capsaicin"" - See capsaicin supplements at Amazon.com.

Calcium supplements: Too much of a good thing? - Science Daily, 6/1/10 - "The incidence of the so-called milk-alkali or calcium-alkali syndrome is growing in large part because of widespread use of over-the-counter calcium and vitamin D supplements ... the obvious preventive strategy against the calcium-alkali syndrome is to limit the intake of calcium to no more than 1.2 to 1.5 grams per day. "Calcium supplements taken in the recommended amounts are not only safe but are quite beneficial. Taken to excess is the problem"" - Opposing study:

  • Serum calcium and the risk of prostate cancer - Cancer Causes Control. 2009 Apr 18 - "These data do not support the hypothesis that high serum calcium levels is a risk factor for prostate cancer. On the contrary, the data suggest that high serum levels of calcium in young overweight men may be a marker for a decreased risk of developing prostate 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):

Antinociceptive Effects of Docosahexaenoic Acid against Various Pain Stimuli in Mice - Biol Pharm Bull. 2010;33(6):1070-2 - "DHA administration dose-dependently exerted an antinociceptive effect against thermal and chemical stimulation in comparison to the control olive oil administration ... These findings suggest that DHA has opiod receptor-mediated pain control activities, and may provide valuable information towards an advanced therapeutic approach for pain control" - See Jarrow Max DHA at Amazon.com.

Glucosamine sulphate in the treatment of knee osteoarthritis: cost-effectiveness comparison with paracetamol - Int J Clin Pract. 2010 May;64(6):756-62 - "The results of the present cost-effectiveness analysis suggested that GS is a highly cost-effective therapy alternative compared with paracetamol and PBO to treat patients diagnosed with primary knee OA" - See glucosamine products at Amazon.com.

Flavonoids, proanthocyanidins, and the risk of stomach cancer - Cancer Causes Control. 2010 Jun 3 - "Strong inverse relations were found for proanthocyanidins. The OR was 0.44 (95% CI, 0.25-0.76) for monomers and dimers combined and 0.36 (95% CI, 0.21-0.63) for polymers with three or more mers. Further adjustment for fruit and vegetables, or vitamin C, did not materially change these associations. This is the first epidemiological study to suggest that dietary proanthocyanidins have a favorable role on gastric cancer risk"

Plasma Matrix Metalloproteinase (MMP)-9 Levels Are Reduced following Low-Calorie Cranberry Juice Supplementation in Men - J Am Coll Nutr. 2009 Dec;28(6):694-701 - "Matrix metalloproteinase (MMP)-9, also known as gelatinase B, is implicated in the development of hypertension and atherosclerotic plaque vulnerability to rupture, an important step in the etiology of cardiovascular diseases ... cranberry juice cocktail (CJC) ... We found that CJC supplementation significantly decreased plasma MMP-9 concentrations (mean +/- SEM: -36% +/- 9%, p < 0.0005; week 12 vs. baseline) while baseline plasma MMP-9 concentrations strongly correlated with the changes noted over the entire intervention (r = -0.71, p < 0.0001). We also show that the reduction in plasma MMP-9 levels was associated with a change in plasma nitrites/nitrates (NOx) concentration over the entire intervention (r = -0.38, p < 0.05; week 12 vs. baseline). Significant correlations were also noted between changes in plasma MMP-9 levels and those of systolic (r = 0.39, p < 0.05) and diastolic (r = 0.60, p < 0.001) blood pressure during the course of the study (week 12 vs. baseline). CONCLUSIONS: Our results show that daily CJC consumption is associated with a decrease in plasma MMP-9 concentrations in abdominally obese men. We hypothesize that polyphenolic compounds from cranberries may be responsible for this effect, supporting the notion that the consumption of flavonoid-rich foods can exert cardioprotective effects" - See cranberry extract at Amazon.com.

Chromium attenuates high-fat diet-induced nonalcoholic fatty liver disease in KK/HlJ mice - Biochem Biophys Res Commun. 2010 May 27 - "Chromium supplementation prevented progression of NAFLD and the beneficial effects were accompanied by reduction of hepatic triglyceride accumulation, elevation of hepatic lipid catabolic enzyme, improvement of glucose and lipid metabolism, suppression of inflammation as well as resolution of oxidative stress, probably through enhancement of insulin signaling. Our findings suggest that chromium could serve as a hepatoprotective agent against NAFLD" - See ChromeMate® products at iHerb.
