Research published online March 1, 2021, by the journal Circulation suggests that eating five servings of fruits and vegetables per day is associated with lower risks of many health conditions and even premature death, compared with eating two servings of fruits and vegetables per day. Researchers believe this could be because fruits and vegetables are major sources of nutrients linked to good health, including potassium, magnesium, fiber, and polyphenols. The most effective combination of fruits and vegetables appears to be two servings of fruits plus three servings of vegetables per day.
