ORAC Values of Acai Berry, Goji Berry, Pomegranate and Mangosteen

ORAC (Oxygen Radical Absorbance Capacity) is a measure of how well antioxidants absorb free radicals. Superfruits such as the Acai berry, Goji Berry, Pomegranate and Mangosteen has quite high ORAC values. The USDA (U.S. Department of Agriculture) ARS (Agricultural Research Service) in their 2007 ORAC values for selected foods has not provided data for these superfruits aside from pomegranate juice which scores 2,341.
To achieve optimum health, USDA recommends an intake of 5,000 ORAC units per day. Daily food consumption for an average person attains only about 20% to 30% of this recommendation. This means a lot more of foods with good ORAC scores like fruits and vegetables must be included in one's daily food intake.
Approximate ORAC scores taken other research institutions like Tufts University and manufacturers of superfruits has come up with the following data:
Superfruit- 1 gram ORAC Value
Acai Berry 3,800
Pomegranate 105
Goji Berry 253
Mangosteen >3,000
Although fruits high in ORAC value gives a lot of antioxidant benefit for the body, the combination of other nutrients and vitamins contained in these fruits raises the overall benefit it gives to our body.
