ORAC value is the Oxygen Radical Absorbance Capacity of food.
ORAC provides us with a method of measuring the overall antioxidant power
(activity) of different foods and supplements and give it a number.
Antioxidants decrease and repair the number of free radicals (damaged cells) in our bodies which help to decrease the damage they cause to our skin, bones and organs.
This method of measurement was developed by the scientists at the National Institute on Aging in Baltimore, Maryland.
They developed the ORAC method and the US Department of Agriculture and Brunswick Labs have been instrumental in perfecting the ORAC assay procedure and testing various foods to determine these ORAC levels.
The higher the ORAC number, the stronger the antioxidant properties of the substance. The USDA recommends we consume 3,000 to 5,000 ORAC units daily.
