Recent Longevity News for the seven days ending 3/24/10.  You should consult your doctor if you are taking any medications.

Diesel exhaust associated with lethargy in offspring - Science Daily, 3/23/10 - "The researchers speculate that certain components, such as ultrafine particles, in the diesel exhaust may be translocated into the offspring of mice, disturbing the normal timetable of development in offspring and leading to the behavioral and physiological abnormalities seen in this study. Alternatively, or additionally, diesel exhaust exposure may affect the mother's behavior toward the pups after birth, which could also cause lethargy and altered brain chemistry"

Similarly, polyp size increased by more than 17% among those in the placebo group but fell by more than 12.5% in those taking the EPA capsules, representing a difference of just under 30% ... the effects of EPA were similar to those produced by celecoxib, which is used to help curb the growth of new and existing polyps in patients with FAP ... celecoxib has been associated with harmful cardiovascular side effects in older patients" - See See Mega Twin EPA at Amazon.com.

Selenium protects men against diabetes, study suggests - Science Daily, 3/17/10 - "The role of selenium in diabetes has been controversial, with some studies suggesting that it raises diabetes risk and others finding that it is protective. Now, research published in BioMed Central's open access journal Nutrition and Metabolism, has shown that, for men, high plasma selenium concentrations are associated with a lower occurrence of dysglycemia ... for French elderly males, having plasma selenium concentrations in the top tertile of the population distribution (1.19-1.97 μmol/L) was significantly associated with a lower risk of developing dysglycemia over the following nine years ... The reason we observed a protective effect of selenium in men but not in women is not completely clear, but might be attributed to women being healthier at baseline, having better antioxidant status in general and possible differences in how men and women process selenium" - [Nutra USA] - See selenium at Amazon.com.

  • Low levels of vitamin D linked to muscle fat, decreased strength in young people - Science Daily, 3/6/10 - "A ground-breaking study published in the March 2010 Journal of Clinical Endocrinology and Metabolism found an astonishing 59 per cent of study subjects had too little Vitamin D in their blood. Nearly a quarter of the group had serious deficiencies (less than 20 ng/ml) of this important vitamin. Since Vitamin D insufficiency is linked to increased body fat, decreased muscle strength and a range of disorders, this is a serious health issue ... The study by Dr. Kremer and co-investigator Dr. Vincente Gilsanz, head of musculoskeletal imaging at the Children's Hospital Los Angeles of the University of Southern California, is the first to show a clear link between Vitamin D levels and the accumulation of fat in muscle tissue -- a factor in muscle strength and overall health" - [Nutra USA] -See vitamin D at Amazon.com.
  • Omega-3 may boost lung function during sport - Nutra USA, 3/3/10 - "Amateur Iranian wrestlers, and not the Hulk Hogan kind, experienced improvements in numerous measures of lung capacity, including lung volume [forced vital capacity (FVC)] and airflows [forced expiratory volume in one second (FEV1)], and found significant improvements following 12 weeks of supplementation and training ...

  • Impact of cocoa flavanol consumption on blood pressure responsiveness to exercise - Br J Nutr. 2010 Jan 19:1-5 - "randomised to consume single servings of either a high-flavanol (HF, 701 mg) or a low-flavanol (LF, 22 mg) cocoa beverage in a double-blind, cross-over design ... the BP response to exercise (area under BP curve) was attenuated by HF compared with LF.

  • Astaxanthin may boost muscle endurance and fat loss - Nutra USA, 2/5/08 - "astaxanthin supplementation "accelerated the decrease of body fat accumulation with exercise training" - [Abstract] - Note:  Astaxanthin is just one of over 600 carotenoids.  The problem with taking large doses of just one carotenoid is that it may cause a deficiency of the others.  I had a study on that but the link went dead.  I tried to find it via http://www.archive.org/web/web.php but it was a .asp web page and it appears that it doesn't work with those extensions. (Click here and see the OnHealth.com, 5/2/00 article).  I take Jarrow Formulas, CarotenALL, Mixed Carotenoid Complex at Amazon.com.
  • Astaxanthin improves muscle lipid metabolism in exercise via inhibitory effect of oxidative CPT I modification - Biochem Biophys Res Commun. 2008 Feb 22;366(4):892-7 - "Astaxanthin increased fat utilization during exercise compared with mice on a normal diet with prolongation of the running time to exhaustion. Colocalization of fatty acid translocase with carnitine palmitoyltransferase I (CPT I) in skeletal muscle was increased by astaxanthin. We also found that hexanoyl-lysine modification of CPT I was increased by exercise, while astaxanthin prevented this increase. In additional experiment, we found that astaxanthin treatment accelerated the decrease of body fat accumulation with exercise training"
  • Sedentary Lifestyles Associated With Accelerated Aging Process - Science Daily, 1/28/08 - "Telomere length decreased with age, with an average loss of 21 nucleotides (structural units) per year. Men and women who were less physically active in their leisure time had shorter leukocyte telomeres than those who were more active. ... "The mean difference in leukocyte telomere length between the most active [who performed an average of 199 minutes of physical activity per week] and least active [16 minutes of physical activity per week] subjects was 200 nucleotides, which means that the most active subjects had telomeres the same length as sedentary individuals up to 10 years younger, on average."" - I'm must be in fat city on this one.  I must have averaged 60 minutes per day since I've been 18 which comes to 420 minutes per week.  Maybe that's the main reason people claim I look young. Plus I've always taken vitamin D which helps with telomere length also. - Ben

  • How much physical activity is enough to prevent unhealthy weight gain? - Obes Rev 2003 May;4(2):101-14 - "The following consensus statement was accepted unanimously. 'The current physical activity guideline for adults of 30 minutes of moderate intensity activity daily, preferably all days of the week, is of importance for limiting health risks for a number of chronic diseases including coronary heart disease and diabetes. However for preventing weight gain or regain this guideline is likely to be insufficient for many individuals in the current environment. There is compelling evidence that prevention of weight regain in formerly obese individuals requires 60-90 minutes of moderate intensity activity or lesser amounts of vigorous intensity activity. Although definitive data are lacking, it seems likely that moderate intensity activity of approximately 45 to 60 minutes per day, or 1.7 PAL (Physical Activity Level) is required to prevent the transition to overweight or obesity. For children, even more activity time is recommended. A good approach for many individuals to obtain the recommended level of physical activity is to reduce sedentary behaviour by incorporating more incidental and leisure-time activity into the daily routine"
