Some vitamins and minerals including vitamins C and E and the minerals copper, zinc, and selenium serve as antioxidants, in addition to other vital roles.
“Antioxidant” is a general term for any compound that can counteract unstable molecules called free radicals that damage DNA, cell membranes, and other parts of cells.
Because free radicals lack a full complement of electrons, they steal electrons from other molecules and damage those molecules in the process.
Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural “off” switch for the free radicals.
This helps break a chain reaction that can affect other molecules in the cell and other cells in the body.
But it is important to recognize that the term “antioxidant” reflects a chemical property rather than a specific nutritional property.
While free radicals are damaging by their very nature, they are an inescapable part of life.
The body generates free radicals in response to environmental insults, such as tobacco smoke, ultraviolet rays, and air pollution, but they are also a natural byproduct of normal processes in cells.
When the immune system musters to fight intruders, for example, the oxygen it uses spins off an army of free radicals that destroy viruses, bacteria, and damaged body cells in an oxidative burst.
Some normal production of free radicals also occurs during exercise. This appears to be necessary in order to induce some of the beneficial effects of regular physical activity, such as sensitizing your muscle cells to insulin.
Pure organic barley juice is rich in antioxidants which servers to remove free radicals in our body and improve our immune systems to have more defence against viruses and bad bacteria.
