ORAC or Oxygen Radical Absorbance Capacity is a unit of measurement that gives us a value or score on different foods and supplements as to the free-radical or oxidative load fighting capacity. Those with higher ORAC units have a better antioxidant effect than those with lower scores. The ORAC scale was developed by scientists at the national Institutes of Health, and while the exact relationship between a food's ORAC value and its health benefit has not yet been well established, it does imply that a higher score does more effectively reduce oxidative load. Oxidative load or free-radicals are what is theorized in the free-radical theory of aging (as proposed by Dr. Denham Harman) as the causative agent for degenerative disease ranging from arthritis to coronary disease and cancers. For a rather extensive list of ORAC values of foods and supplements visit www.oracvalues.com.
A few examples include:
Vitamin A 1.25 mmTE/g
Vitamin E 1.25 mmTE/g
Lycopene 58 mmTE/g
Astaxathin 51 mmTE/g
coQ10 11 mmTE/g
Chia 70 for white seed and 98 for dark seed mmTE/g
Krill 378 mmTE/g
