As strange as it sounds, a new research study published in the FASEB Journal (http://www.fasebj.org), suggests that the "healthy" ingredient(原料,要素) in red wine, resveratrol(白藜芦醇) , may prevent the negative effects that spaceflight and sedentary(久坐的) lifestyles have on people. The report describes experiments in rats that simulated the weightlessness of spaceflight, during which the group fed resveratrol did not develop insulin resistance or a loss of bone mineral density1, as did those who were not fed resveratrol. According to Gerald Weissmann, M.D., Editor-in-Chief of the FASEB Journal, "There are overwhelming data showing that the human body needs physical activity, but for some of us, getting that activity isn't easy. A low gravity environment makes it nearly impossible for astronauts. For the earthbound(只在地面的) , 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 deterioration2(恶化,退化) until someone can get moving again."

Scientists studied rats that underwent simulated weightlessness by hindlimb(下肢) tail suspension and were given a daily oral load of resveratrol. The control group showed a decrease in soleus muscle mass and strength, the development of insulin resistance, and a loss of bone mineral density and resistance to breakage. The group receiving resveratrol showed none of these complications. Study results further demonstrated some of the underlying3 mechanisms4 by which resveratrol acts to prevent the wasting adaptations to disuse-induced mechanical unloading. This study also suggests that resveratrol may be able to prevent the deleterious(有毒的) consequences of sedentary behaviors in humans.

"If resveratrol supplements are not your cup of tea(心爱之人或物) ," Weissmann added, "then there's good news. You can find it naturally in red wine, making it the toast of the Milky5 Way."
