Pomegranates Yield Promising Anti-Aging Compound

(Gizmodo) A compound found within pomegranates, when transformed by bacteria in the gut, has been shown to rejuvenate cellular function and reverse the effects of aging on muscles, at least in worms and rodents. On their own, pomegranates may not confer these life-extending qualities—but the discovery could lead to powerful anti-aging medicines.
The molecule responsible for this rejuvenation effect is called urolithin A, but it isn’t actually found in pomegranates. After eating the delectable juice from a pomegranate, natural substances known as ellagitannins are broken down in the stomach and then converted into urolithin A by our intestinal bacteria…
A team of scientists from the Swiss Federal Institute of Technology in Lausanne, with the help of biotech firm Amazentis, has shown that this biological byproduct enables muscle cells to protect themselves against a major cause of aging. In the words of the researchers, urolithin A conferred “powerful and measurable” anti-aging effects on nematode worms and rodents. Human trials are already underway, but these preliminary findings have already been published.
