ORAC Values: Antioxidant Values of Foods & Beverages

The antioxidant values of foods listed are expressed in ORAC (Oxygen Radical Absorbance Capacity) units, a unit of measurement for antioxidants developed by the National Institute on Aging (NIA) at the National Institutes of Health (NIH).

You can browse foods alphabetically to find their ORAC values, or if you want to get straight to the best antioxidants and anti-aging “superfoods”, you can view them sorted by their ORAC values – higher values generally imply stronger antioxidant capabilities.

We regularly update this database with new foods as well as existing value updates, when applicable. Date of most recent update: June 1, 2016.

Hint: type a keyword into the search box to quickly filter (e.g. “spice,” “nuts,” “wine,” “apple,” “pizza,” “meat” etc.)

What are ORAC Units?

The ORAC (Oxygen Radical Absorbance Capacity) unit, ORAC value, or “ORAC score” is a method of measuring the antioxidant capacity of different foods and supplements. More than two decades in the making, it was developed by scientists working at the National Institutes of Health (NIH) and USDA. While the exact relationship between the ORAC value of a food and its health benefit has not been established, many scientists believe that foods higher on the ORAC scale will more effectively neutralize free radicals. Although unproven, according to the free-radical theory of aging, this may slow the oxidative processes and free radical damage that can contribute to age-related degeneration and disease.
