Have you ever looked for the ORAC value of the foods you eat?  If you haven’t, you might want to start!  ORAC stands for oxygen radical absorbance capacity or, in simpler terms, the antioxidant activity of foods. 

According to the modern free radical theory of aging, putting higher amounts of antioxidants into the diet slows oxidative processes and free radical damage that contribute to age-related degeneration and disease.

Studies indicate that the antioxidant activity of high ORAC foods that protects cells can:

  • Raise the antioxidant power of human blood;
  • Prevent some loss of long-term memory and learning ability in middle-aged rats;
  • Maintain the ability of brain cells in middle-aged rats to respond to a chemical stimulus and protect tiny blood vessels (capillaries) against oxygen damage.

The US Department of Agriculture has determined that a person should be consuming foods and supplements with at least 3,000 to 5,000 ORAC units per day.

To measure the antioxidant activity of foods, scientists at the National Institutes of Health have developed a method of determining the oxygen radical absorbance capacity (ORAC) for foods. The ORAC value shows how quickly a food reduces highly reactive oxidizing (rusting) compounds into harmless chemical substances that the body has successfully uncoupled. Those foods providing the best reducing power per 100 grams earn the highest ORAC scores. Among these foods, the humble noni fruit leather showed a more potent oxygen reducing value than popular antioxidants like blueberries, strawberries, and raspberries. 

When used in a daily two-by two- inch serving size, noni fruit leather provides 6,024 ORAC units, more than most of the other antioxidant-rich foods like berries and pomegranate.
