Red wine could help astronauts stay strong on Mars

While astronauts floating around in the International Space Station (ISS) would have access to exercise machines to counteract these effects, they would have no such equipment on Mars. The gains they'd have from pumping iron at the Gold’s Gym ISS would be gone fast. However, researchers might have found a dietary supplement that can counteract this problem: resveratrol, an antioxidant found in grape skin, blueberries and perhaps most famously, red wine.
