A study conducted by a university professor found that drinking red wine in moderation, as shown in lab tests on mice, can increase mobility and balance in elderly humans. The study identified beneficial compounds in red wine and blueberries that were shown to have these effects. However, the study only used mice and did not account for human subjects' medical histories or diets, so the effects on humans are not certain. It may be more sensible to get these compounds through eating fruit rather than drinking the amount of wine needed to match the benefits.
