Resveratrol Prevents Harmful Effects Of Lack Of Physical Activity

June 29, 2011: 11:50 AM EST
A study by French researchers has found that resveratrol curbs insulin resistance and prevents bone density loss associated with spaceflight weightlessness and lack of physical activity. Experiments with rats in which the weightlessness experienced by astronauts was simulated showed that animals who were not fed resveratrol lost soleus muscle mass and strength, developed insulin resistance, and lost bone mineral density and resistance to breakage. Animals who received resveratrol experienced none of these effects. “[Resveratrol] could thus be envisaged as a nutritional countermeasure for spaceflight but remains to be tested in humans,” the researchers concluded.
