The term "antioxidant"
We must start with the fact that everything on Earthsubject to total destruction, which occurs under the influence of oxygen, and in other words - oxidation. If for example, take a metal pipe, then we know exactly what is under the influence of the environment, it can rust and and prevent this from happening - it must be covered with paint. Similarly, the act and antioxidants - they protect the body at the cellular level of the impact of molecules that can damage the body. Such molecules are called free radicals.
Free radicals also are abnormalmolecules that have an unpaired electron in the last electronic level. Once in the body, they interact with enzymes, lipids, and sometimes with whole cells, taking away their electrons, thereby disrupting the chemical balance of the body. The described process is permanent, there is a failure at the entire system, a person becomes ill. These diseases may be a conventional common coldAnd cardiovascular diseases, and cancer. Suffice it to say on lipid oxidation of free radicals, which are the result of lipid peroxides formation which scientists directly associated with the beginning of cancer, cardiovascular diseases, and aging of the skin and immunosuppression.
So what is an antioxidant able to help? It completely neutralizes free radicals, giving him its electron. Thus, reaction breaking chemical balance stop. This process is laid down in the human at birth, at first he was very powerful, but eventually calms down, because it requires additional makeup outside.

Selenium can be found in algae, fish, liver, cereals, sunflower seeds conventional. His daily required dose is around 55 mg per day for both men and women.
Stop the processes started by free radicals. Stop the occurrence of diseases of the cardiovascular system, Breast Cancer, Skin, cervical, lung, colon and bladder. Also, protect cellular DNA from damage. Improves immunity and overall resistance to environmental hazards.
Norm that doctors would recommend notexist. High levels of this component observed in carrots, sorrel, cabbage, green onions, spinach, parsley, and their high content in beef liver, green peas, melons, broccoli and many other products.
Herbs and Plants
There are special herbs andPlants possessing antioxidant properties. This is due to the fact that they grow under such conditions that they need to survive high resistance to external factors. Eating these products, we also improve their resistance.
Here are the most well-known plants and herbs:
