Strawberries boost immunity
“Strawberries are an excellent source of vitamin C,” says Toronto-based registered dietitian Madeleine Edwards. Most mammals—except for humans—have the ability to produce vitamin C naturally, which is why it’s so important to get your daily requirement. “One serving of strawberries contains 51.5 mg of vitamin C—about half of your daily requirement,” Edwards says. “Double a serving to one cup and get 100 percent.” Vitamin C is a well-known immunity booster, as well as a powerful, fast-working antioxidant. A 2010 UCLA study discovered that the antioxidant power in strawberries becomes “bioavailable” or “ready to work in the blood” after eating the fruit for just a few weeks.
