A key compound in red wine known as resveratrol appears to protect against many of the health ravages associated with growing old, new animal research reveals.
[…] Daily consumption of the compound — also found in the skin of grapes and the crust of peanuts and walnuts — broadly improved the long-term quality of life of middle-aged mice, although most mice did not end up living longer.
[…] the researchers now compared the health and life spans of middle-age mice given either a standard diet or a calorie-restricted diet, with or without high or low daily dosages of resveratrol.
De Cabo and his colleagues found that resveratrol had the same positive impact on mouse livers, muscles, hearts and bones as calorie restriction alone.
Regardless of dietary protocol, the general health and vigor of mice on a long-term regimen (approximately one year) of resveratrol improved overall, without apparent side effects. However, only mice consuming resveratrol alongside a high-calorie diet were found to actually live longer.
