What Is The ORAC Rating?
ORAC - The New Standard For Antioxidant Evaluation
ORAC is short for "Oxygen Radical Absorbance Capacity", and is a test tube analysis that measures the total antioxidant power of foods and other chemical substances. It was developed by scientists at the USDA (United States Department Of Agriculture).
Scientists discovered that a small group of "super foods" have up to twenty times the antioxidant power of other foods. In studies with animals that were fed high-ORAC foods had lower biological ages as measured by memory, balance, and capillary strength.
High ORAC Foods Protect Against Oxidative StressOxygen free radicals are chemicals that occur naturally in the body by way of oxidation. Just basic daily activities such as digestion, and movement such as walking or exercise is enough to produce oxygen free radicals. Exposure to rancid food, polluted air, sunlight and electricity and also from cell phone or microwave use will also induce oxygen free radicals. Foods or supplements with a high ORAC score may protect your cells from oxidative stress.
The ORAC antioxidant food rating cannot be easily measured, and it is the combination as well as the totality of the beneficial nutrients such as flavonoids and polyphenols which give the total score. You will find that various types of fruits and vegetables have different ORAC. It is recommended that you eat five portions of fruit and vegetables, and if you do, your average ORAC score will be about 1,750 - 2,000 ORAC units. If you are vigilant and eat those fruits and vegetables with a particularly high ORAC score, you can do so much better, even up to 5,000 units per day, the optimal amount indeed. You may be surprised to hear that many different berries have a very high ORAC score.
Studies have shown that eating foods with the highest ORAC rating can increase the amount of antioxidants in the blood by about 10% – 25%. According to experts, the result of consuming about 5000 ORAC units per day from fruits and vegetables will have a significant beneficial effect on the blood and tissue anti-oxidants.
Early findings suggest that eating plenty of high-ORAC list fruits and vegetables...such as spinach and blueberries may help slow the processes associated with aging in both your body and brain. So take note, it might just be possible to reduce the risk of diseases and ageing....including senility...simply by adding high-ORAC rated foods.
