orac index

ORAC is an abbreviation for oxygen radical absorbance capacity, a measure that shows the ability of food and other substances to quench oxygen free radicals in a test tube. While “ORAC” and “antioxidants” are different things, eating a combination of foods that have demonstrated high ORAC scores has also boosted blood antioxidant levels.

The antioxidant values of various foods are listed as units of measurement for antioxidant content which was originally developed by the National Institute on Aging (NIA) at the National Institutes of Health (NIH).

The highest ORAC value of any known food is found to be in Moringa oleifera. Moringa oleifera or horseradish tea was recently found to have the highest antioxidant levels ever discovered in food, even higher than blueberries that were thought until recently.

In addition to vitamin C and beta-carotene, these include, moringa oleifera contains quercetin—the powerful antioxidant that is proven to lower blood pressure.

    Thanks for sharing, but I still don’t understand the importance of the antioxidants and the connection among orac index and antioxidants. English is not my first language so this can be the reason.

    ORAC stands for Oxygen Radical Absorbance Capacity. The ORAC unit, ORAC value, or ORAC score is a method developed by scientists at the National Institute of Health and Aging (NIH) to measures the antioxidant capacity of different foods. It’s a lab test that attempts to quantify the “total antioxidant capacity” (TAC) of a food by placing a sample of the food in a test tube, along with certain molecules that generate free radical activity and certain other molecules that are vulnerable to oxidation .

    Helpful stuff so far! Antioxidant Values of Foods & Beverages. The antioxidant values of foods listed are expressed in ORAC units, a unit of measurement for antioxidant content which was originally developed by the National Institute on Aging (NIA) at the National Institutes of Health. Thanks and keep up the great work!
