Top 20 Foods High in Antioxidants

Antioxidants in Food

There are many foods high in antioxidants, the vitamins and minerals that help counteract damage from free radicals. Adding just five servings of these foods to your diet a day could have a significant impact on your health.

How Antioxidants Are Measured

USDA Scientists developed a scale that rates and measures the antioxidant content of various natural plant foods. This scale is called ORAC (Oxygen Radical Absorbance Capacity). This database holds data for 277 food items.

The National Cancer Institute suggests a daily diet including at least five to nine servings of carotenoid antioxidant-rich foods. In reality, people eat closer to one or two servings a day. The best way to ensure adequate intake of quality antioxidants is to eat a variety of foods high in antioxidants in your daily diet.
