1. Blueberries
“It almost sounds ridiculous to list the research-backed benefits you can get from blueberries,” Talbott says, pointing to their ability to lower your risk for heart disease, reduce joint and muscle pains, and curtail oxidative stress (the naturally occurring stress produced by cell respiration). Blueberry’s power comes from the compound oligomeric proanthocyanidins, and Talbott says that you don’t need a ton of it to get results: a half-cup per day of fresh or frozen blueberries results in a “significant longevity benefit.” Plus, there’s plenty of research showing that blueberries can reduce post-exercise stress and inflammation among athletes. As for the general population, in 2013, researchers revealed that—at least for women—getting three servings of berries per week cut heart attack risks by one-third.
