Resveratrol May Not Extend Life | The Scientist.
Hector et al. recently published a meta-analysis of the overall effects of resveratrol (link below).� Overall, resveratrol it seems to decrease risk of death, but the strength of the effects are highly variable depending upon species. It seems to extend lifespan reliably in yeast and worms, but not so reliably in other critters. Too bad! We all love our red wine… we’ll have to await the results of human trials… Who’s with me??

We all know that nutrition is important to our health, but it’s when we see articles like this recently published one, “Blueberry extract prolongs lifespan in Drosophila melanogaster,” or this slightly older one, “Concord grape juice supplementation improves memory function in older adults with mild cognitive impairment” that we are reminded of just how literal and direct the positive results of a healthy diet rich in fruits and vegetables can be.
We all assume that a healthier diet will help to protect us from disease and disorder, but does it actually keep us stronger as we age? A primary research article published online today in the Journal of Gerontology shows us just that: Healthy diets mean stronger muscles and higher walking speed for individuals aged 60 and over! Concrete proof of the major impact of diet upon our physical wellbeing, not only for keeping physical ailments like heart disease and diabetes at bay, but also for maintaining our own physical strength and independence from middle age onward.

Systemic inflammation is a major contributor to age-related dysfunction. Previous research has hinted that a Mediterranean-style died may be capable of lowering systemic inflammation (in addition to helping you drop weight and lowering your risk of metabolic disease). An article published online today shows that a Mediterranean-style diet, plus supplementation with the antioxidant Coenzyme Q10 decreases the expression of genes related to inflammatory response and endoplasmic reticulum stress in people 65 years or older. Mmm… more reasons to eat Mediterranean-style… There aren’t any general news articles about this publication yet, but if you have access through your library, you can get the primary research article here: http://biomedgerontology.oxfordjournals.org/content/current
