According to a study done by Harvard University, there’s an antioxidant found in red wine that can prevent bone and muscle loss in humans. Until now, astronauts have had to exercise constantly to ensure their muscle loss is kept to a minimum. Now, this compound, also found in chocolate, can be added to their rations to help slow the loss.

The compound is believed to have anti-inflammatory and anti-diabetic properties, and the next steps in their research is to figure out just how much is needed to keep the astronauts in prime physical condition.
