Red and Black Grapes' Nutrients

An October 2015 nutrition education review published in the Iranian Journal of Public Health found that a sufficient intake of fruits and vegetables leads to fewer chronic diseases and better bodyweight management. The researchers point out that the World Health Organization recommends adults consume at least five servings of fruits and vegetables per day, excluding starchy vegetables.

Adding grapes to your diet can serve as a colorful, tasty way to reach this recommended daily dosage.
