The scientific community measures the antioxidant levels in foods using the ORAC (Oxygen Radical Absorbance Capacity) test. The higher the ORAC value, the more antioxidants a food provides.
Scientists have discovered that berries have some of the highest antioxidant levels of any fresh fruits. Raspberries, for example, contain an especially high level of antioxidants—three times more than kiwis and 10 times more than tomatoes.
The average serving of fresh or lightly cooked produce provides between 600 and 800 ORAC units. But berries blow these values away—one cup of blueberries has an ORAC value of 5486, followed by blackberries at 4654, strawberries with 3520, and raspberries at 2789. Scientists believe that eating between 2000 and 5000 ORAC units daily may increase the body's antioxidant supply high enough to result in positive health outcomes.
Raspberries
Slightly tart and juicy, the raspberry is a nutritional powerhouse in a tiny package. Raspberries are rich in ellagic acid (which provides the majority of the berry's antioxidants), and anthocyanins (which give raspberries their deep, red color and exhibit antimicrobial properties). As if their high antioxidant content wasn’t enough, raspberries are also great sources of the vitamins and minerals riboflavin, niacin, folate, magnesium, potassium, copper, manganese and vitamin C. *Note: Raspberries contain oxalates, a naturally-occurring substance that can build up in body fluids and crystallize, causing health problems. If you have any kidney or gallbladder problems, you may want to avoid raspberries for this reason.
