ABSTRACT:
The article is to do an literature review in the role of berries as an antioxidant. Antioxidants are widely used in dietary supplements and have been investigated for the prevention of diseases such as cancer, coronary heart disease and even altitude sickness. There are many berries such as barberry , bilberry , cranberry , elderberry. The dietary supplementation with fruit or vegetable extracts is high in antioxidants such as the berries. These antioxidants can decrease the enhanced vulnerability to oxidative stress that occurs in aging and these reductions are expressed as improvements in behavior. Free radicals are atoms or groups of atoms with an odd (unpaired) number of electrons and can be formed when oxygen interacts with certain molecules. Cells may function poorly or die if this occurs. An antioxidant is a molecule that inhibits the oxidation of other molecules. Berries are a particularly rich source of polyphenols. They also contain other bioactive substances, such as vitamin C. Vitamin C is natural antioxidant and it is present in these berries. The reason of this article is to high light the role of berries (blueberry , raspberry , gooseberry, strawberry) as an antioxidant.
