Special Enzymes Could Slow the Aging Process
Aging can be an unkind process.  Diseases like diabetes, osteoarthritis, and heart disease can trigger a whole host of symptoms that can take theenjoyment out of life. 
If you're looking for a way to slow down this seemingly inevitable process, here's some exciting health news from researchers in Australia: a special class of enzymescalled sirtuins could help protect your cells. 
{ Sirtuins are a family of NAD+-dependent protein deacetylases widely distributed in all phyla of life. Accumulating evidence indicates that sirtuins are importantregulators of organism life span. In yeast, these unique enzymes regulate gene silencing by histone deacetylation and via formation of the novel compound 2'-O-acetyl-ADP-ribose. In multicellularorganisms, sirtuins deacetylate histones and transcription factors that regulate stress, metabolism, and survival pathways.}
Now, it just so happens that the performance of sirtuins can be boosted bestby resveratrol. That's right-the antioxidant found in abundance in red wine. Of all the compounds the researchers tested, resveratrol was the top candidate for increasing the cell-protecting power ofsirtuins.
When sirtuins are active, they allow cells to survive damage, delaying their death. In people, they play a role in stopping the normal cellular cycle that ends with old cells killing themselvesoff. Sirtuins help cells to live longer by repairing DNA and stimulating the production of protective enzymes. In other words, sirtuins seem to encourage the cells to switch to survival mode, enablingthem to live longer.
By eating foods high in resveratrol, you can boost your production of sirtuins and better protect your cells from dying as they age. Resveratrol is found in wine, grape juice,grapes, peanuts, and some berries, including blueberries, bilberries, and cranberries. However, in grapes, resveratrol is found primarily in the skin. White and blush wines usually have less...
