Red Wine

A glass of red wine may help lengthen your life span.

Researchers have found new evidence showing that resveratrol, a compound found in red wine, may play a role in preventing cell aging.

The study in rodents found that when mice had a particular gene -- SIRT1 -- inactivated, resveratrol had no effect on them.

But tests of muscle tissue in mice with a normal SIRT1 gene that were given resveratrol found that the substance boosted mitochondrial function.

Mitochondria provide the energy to cells.

A decrease in mitochondrial energy production has been linked to a variety of diseases, including diabetes and Alzheimer's disease, as well as to the aging process itself.

Instead, the goal is to develop synthetic resveratrol compounds that activate SIRT1 and could be taken as medication.

The study's author at Harvard Medical School in Boston says, the goal is to develop synthetic resveratrol compounds that activate the gene and could be taken as medication.
