Antioxidants, ORAC Value and Concentrated Resveratrol


Antioxidants for breast cancer recoveryBy Ellen Kamhi, PhD, RN, AGH, AHN-BC.

The public associates antioxidants with health. Antioxidants occur naturally in a large amounts of fresh fruits, vegetables and botanicals. They are being used extensively in oral supplements and natural cosmetic and personal care products.

The FDA has strict guidelines on the use of the term ‘anti-oxidant’. For examples, manufacturers cannot just splash “ high in antioxidants” on the label (which is often done). If a statement is made about a high antioxidant value, the manufacturer must actually reference a known and measureable antioxidant, such as vitamin A or vitamin E. They must then reference the RDA (also known as the RDI or reference daily value), and specifically show that their product contains an amount of that individual nutrient which is equal to or higher than the RDA value. With the increased activity of the FDA, many manufacturers are receiving notices that they are not complying with labeling laws.

One of the up and coming concepts in the Antioxidant area is measurement of the ORAC value. ORAC stands for “Oxygen Radical Absorbance Capacity”. ORAC describes a laboratory analysis of the antioxidant activity against various free radicals, such as the peroxyl radical, which is one of the most common reactive oxygen species (ROS) that cause damage to cell membranes in the body. ORAC measures the ability of substances to neutralize this free radical. The greater the amount of free radicals a nutrient or product can combat, the higher its ORAC score. This standard was developed in a collaborated effort by the National Institute on Aging and the USDA Human Nutrition Research Center on Aging . Consumers are becoming more interested in ORAC value as they become more educated about what this means. Some of the highest ORAC scoring products in the world include many items that are called ‘Super Fruits” such as Pomegranate, Acai, Mangosteen and Goji, along with Green Tea and Muscadine Grape.

There are many Super Fruit products available , such as Nature’s Answer® Orac Super 7, which guarantees 5000 to 7000 Orac Units in one serving! It is a blend of many of the super fruits mentioned above (Acai, Mangosteen Goji, Green Tea, Muscadine Grape) known to be high in Orac Value.

Resveratrol is a concentrated grape derived ingredient which has also shown a serge of popularity in recent years, as an anti-aging antioxidant. Resveratrol is also found in high amounts in the wild plant called Japanese Knotweed (Polygonum cuspidatum). Commercially available supplements offer Resveratrol in both liquid and capsule form. Read your labels carefully, since some brands also include sweeteners and preservatives, such as potassium sorbate, while other brands are free of sweeteners and additives.

Muscadine Grape is a rising star in the antioxidant category. Muscasdine Grapes are a berry-like grape that is native to USA. It contains resveratrol in its skin and has a very high level of naturally occurring health supporting natural constituents, such as ellagic acid (a polyphenol antioxidant), anthocyanins, flavoniods and other healthful compounds. Muscadine grapes often grow as wild edible, medicinal plants found on fences around farms and fields. The muscadine berry is extremely resistant to pests and fungus probably due to its extremely thick skin, and is not sprayed with pesticides or herbicides. Include a variety of brightly colored fruits and vegetables in your daily diet to insure that you are getting an array of beneficial antioxidant compounds !

  1. Annie, it may be time to really learn about antioxidants.——until now we were all taught that foods high in anti-oxidants were great, as they still are, however, 1 molecule of an anti-oxidant will kill a free radical—the CAUSE of oxidative stress in the cells and oxidative stress is linked to over 200 plus diseases. http://www.pubmed.gov Search: oxidative stress We now know how to allow the body to upregulare glutathione–God’s natural given antioxidant and with Protandim 1 molecule of SOD–super oxidide dismutase—the body ERADICATES free radicals at a rate of 1:1000000 each second of everyday. http://www.abcliveit.com To order this God given Breakthrough: http://www.mylifevantage.com/225281
