Liquid antioxidant ORAC are concentrated heavily in foods with a lot of color. That is why grapefruits, berries, and citrus fruits are among the top-ranked food sources of antioxidants. Various studies have been conducted outlining the many benefits of liquid antioxidant ORAC from helping prevent cancer to reducing the risk of heart attacks. Liquid antioxidant ORAC have also been shown to play a role in age reversal, particularly on degenerative diseases such as Alzheimer’s disease and Parkinson’s disease.
What is Liquid Antioxidant ORAC?
ORAC is the acronym for Oxygen Radical Absorption Capacity. It is a type of test developed by scientists to determine the antioxidant potency of a food. The higher the liquid antioxidant ORAC value is, the better the antioxidant’s capacity to fight scavenging free radicals.
Sixteen hundred liquid antioxidant ORAC units are about equivalent to two servings of fruits and vegetables. There are a number of excellent sources of liquid antioxidant ORAC units and most of them you would hardly expect to contain so much of this beneficial substance.
The US Department of Agriculture recently released the new top 20 list of food sources that contain the highest concentration of liquid antioxidant ORAC. Top on the list is the small red bean, followed closely by the more popular wild blueberries, cranberries, and raspberries. A few nuts also made it to the list, such as pecans, walnuts, and hazelnuts. Vegetables included russet potatoes, sprouts, and red cabbages.
Interestingly enough, it has been noted that fruits and vegetables with high liquid antioxidant ORAC units are those that have dark pigmentations in the fruit or the skin. Scientists attribute this to the presence of anthocyanin pigments. These pigments are responsible for the red, purple, and blue colors of many fruits, vegetables, cereal grains, and flowers. Anthocyanins generated much interest even long before the discovery that they can be quite effective liquid antioxidant ORAC substances.
Today, over 300 structurally distinct anthocyanins have been identified in nature. Researchers believe that these substances may have possible health benefits as dietary liquid antioxidant ORAC. Anthocyanins are one class of flavonoid compounds, which are widely distributed plant polyphenols. Flavonols, falva-3-ols, flavones, flavanones, and flavanonols are additional classes of flavonoids that differ in their oxidation state from the anthocyanins. Solutions of these compounds are colorless or pale yellow. Berries are said to contain the highest concentration of these beneficial substances and for this reason, many antioxidant dietary supplements today almost always contain some compound from berry fruits.
