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.
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

An article in the New York Times is reporting that Dr. Dipak Das (U. Connecticut), is under investigation for scientific misconduct – specifically, for reporting fraudulent data. Dr. Das was one of the early contributors to research on Resveratrol, a potential anti-aging compound upon which millions of research dollars have since been spent. Many experts on Resveratrol were unaware of Dr. Das and his work until the reports of fraudulent data surfaced. Although much research since Resveratrol’s beginning has had positive results, scientific misconduct is a serious issue and can adversely impact not only the progress of the field, but can waste millions of dollars of taxpayer money.
