Recent Longevity News for the seven days ending 1/1/03:

CLA: Beneficial Fatty Acid - Health Supplement Retailer 01/03 - "Studies in animals22,23 and humans24 indicate that CLA supplementation decreases body fat and increases lean muscle mass. The increase in lean muscle mass is most pronounced in individuals who are exercising regularly. CLA appears to reduce the ability of fat cells to take up fats from the bloodstream; it also inhibits the formation of new fat cells. CLA also helps cells burn fat at a higher rate, while fueling and preserving muscle, leading to a reduction in fat and an increase in lean muscle mass" - See iHerb (5% discount code "qc") or Vitacost CLA products.

Testosterone Levels in Older Men Predict Cognitive Status - Medscape, 12/30/02 - "the progressive physiological decline in testosterone secretion in aging men contributes to selective losses in cognitive functions that may be reversed at least in part by testosterone supplementation"

S-Adenosyl-L-Methionine Results Similar to Imipramine in Major Depression - Doctor's Guide, 12/30/02 - "A total of 146 patients received 400 milligrams per day of intramuscular SAMe and 147 received 150 mg/d of oral imipramine ... SAMe and imipramine did not differ significantly on any efficacy measure, either main or secondary ... Adverse events were significantly less in patients treated with SAMe compared to those treated with imipramine" - Note:  There seems to be conflicting studies on whether oral SAMe is poorly absorbed.  I've added absorption studies near the bottom of my SAMe page.  Maybe the difference is "Enteric coating" tablets as with the Jarrow SAMe.

• SAM-e (S-Adenosylmethionine) - James South - "Because SAMe tablets are enterically coated, they should NOT be cut in half to achieve a lower dose- the SAMe may then break down before absorption"

Eicosapentaenoic Acid Enhances Vasodilatation in Coronary Artery Disease Patients - Doctor's Guide, 12/30/02 - "The omega-3 polyunsaturated fatty acid EPA has been shown to improve endothelium-dependent vasodilatation in atherosclerotic arteries" - I think that 1800mg/kg has to be a misprint.  For a 70 kg (154 lb.) person, that would be 126000 mg/day.  That doesn't seem possible.  That's over a quarter pound of EPA/day (.0022 * 126 = .2772) or about a half to one pound of fish oil per day.  A pound of oil is 4091 calories.  I think it has to be 1800mg/day vice 1800mg/kg.

Lutein Holds Promise for Cataract Sufferers - Health Supplement Retailer, 12/30/02 - "gave 17 cataract patients 15 mg of lutein (as 12 mg of all-trans-lutein and 3 mg of 13/15-cis-lutein present as mixed lutein esters) or 100 mg of vitamin E (as alpha-tocopherol) or a placebo three times per week for up to two years ... The lutein group also experienced improved visual acuity and glare sensitivity, while the vitamin group was found to experience only a maintenance in visual acuity and the placebo group a decrease" - Click here for the actual study.  See iHerb (5% discount code "qc") or Vitacost lutein products.

Good night's sleep found to be important in keeping weight off - Union Tribune, 12/29/02 - "sleep loss has been shown to affect the secretion of cortisol, the primary stress hormone, which over the short run provides a burst of energy and stamina. But if cortisol levels stay high, the body craves carbohydrates and foods high in calories and fat. It also slows metabolism and prompts the body to store fat via a fat-gathering enzyme that gravitates toward the abdomen more than any other part of the body"

Whole Grain Intake Reduces Risk of Type 2 Diabetes in Men - New Hope Natural Media, 12/26/02 - "People who consumed the highest amount of whole grains (3.2 servings per day) had a 30% to 40% reduction in risk of developing type 2 diabetes compared with those who ate less than 1 serving a day ... The benefits of whole grains may be due to their increased content of fiber, which is mostly removed in process of refining whole grains to white flour. However, some studies suggest that the higher amount of magnesium in whole grains also contributes to the lower risk of diabetes"
