Antioxidants, Free Radicals and Oxidative Stress





There is some research though that antioxidant fruits may be taken better if you actually include them in your diet. Fruit, vegetables, and cereals in your diet have additional benefits compared to taking antioxidant fruits supplements. Scientists point out that this might be because consuming antioxidant fruits in food may provide a combination of lesser-known but potent antioxidant substances, which may afford greater effect than that of any single nutrient or individual antioxidant supplement. 

Antioxidants, it seems, have created quite a huge wave in the scientific community that is devoting countless journals and magazine articles about their many benefits. Antioxidants are substances that work on free radicals, or more particularly work to counteract the damaging effects of these harmful oxygen byproducts. 

In the study about antioxidant juice from pomegranates, researchers have found that the substance can effectively reverse the progression of atherosclerosis, or the hardening of the arteries. Atherosclerosis causes decreased blood flow that can lead to heart attacks or strokes. The tests showed that antioxidant juice from pomegranates reduced the effects of stress on human blood vessel cells by stimulating the production of nitric oxide. 

During the research, the group tested the ability of the antioxidant red grapes Activin in neutralizing and inhibiting the damage caused by fee radicals in the brains and livers of mice. Afterwards, they then compared the effects of the new antioxidant red grapes compound to the more popular antioxidants - vitamins E, C, and beta-carotene. 

The data on antioxidant vitamins is incomplete for the most part but up to 30 percent of Americans are already taking some form of antioxidant vitamin supplement along with their diet. Due to the lack of sufficient data to support the success of antioxidant vitamins supplement against cardiovascular diseases and other such degenerative illnesses, the American Heart Association does not recommend using antioxidant vitamins supplements. 

Molecules consist of one or more atoms of one or more elements joined together by chemical bonds. A typical atom is comprised of a nucleus - neutrons, protons, and electrons. Electrons are those negatively charged particles that orbit the cluster of protons in an atom. When there are eight electrons in an orbit, it means that that particular orbit (or shell as it is called) is full which further means the atom is stable.
