This review analyzed existing research on resveratrol (a compound in red wine) and found it showed protective effects against stress and disease in animal studies. It may have potential benefits for skin cancer prevention and heart health, though the researchers acknowledge concerns about whether our bodies can actually absorb and use it effectively.

This wasn't a new experiment—researchers reviewed and summarized all existing in vivo (in living organisms) studies on resveratrol to assess what the current evidence actually shows.
