Abstract

This brief overview of polyphenols describes what they are, where they are found in foods, and why some may be important to human health. Polyphenols are widely diverse and ubiquitous non-nutrient compounds in plant foods that may have physiological effects on the human body. Sources of polyphenols include fruits and vegetables, whole grains, herbs and spices, coffee, cocoa, and tea. Accumulating research suggests the potential role of polyphenols in promoting health.
