Red Wine Substance May Promote Insulin Sensitivity, Bone Health
Numerous studies have suggested that drinking an occasional glass of red wine or taking dietary supplements that contain grape-based phenols may confer a plenitude of health benefits. Now, those benefits may extend to low Earth orbit.
Recently, a group of French researchers determined that a compound found in red wine may help reduce the onset of bone loss brought on by weightlessness, like that experienced by astronauts. The results, which appeared in the Federation of American Societies for Experimental Biology (FASEB) Journal, pointed to resveratrol as the chemical key to bone health in zero Gs.
For the study, scientists dosed laboratory rodents with resveratrol, a compound found in grape skins and wine. After days of simulated weightlessness, those animals given the substance did not display any bone deterioration, muscle loss or insulin resistance, while those given no resveratrol experienced all of these complications.
The team expressed excitement for resveratrols applications in space and on terra firma.
“For the earthbound, barriers to physical activity are equally challenging, whether they be disease, injury, or a desk job. Resveratrol may not be a substitute for exercise, but it could slow deterioration until someone can get moving again,” Gerald Weissmann, editor of the FASEB Journal, concluded.
