The free radicals are atoms, in general of oxygen, highly reagents and unstable, that are liberated when the food is metabolized in our cells to produce energy. Also they take place for external influences when our organism receives the impact of diverse pollutants or radiations. The instability of the free radicals is due to the fact that they have lost one of his electrons and try to restore it taking it of other atoms. This believe a chain reaction that causes big damages to our cells, damages that are evident in aging and a good number of illnesses.

On the other hand, the free radicals also join several chemical substances of the body, between which the ADN is, provoking damages in the same ones. It is believed that the ADN of every cell is struck approximately 10,000 times every day by free radicals. Our body possesses a series of biological mechanisms to deactivate these free radicals and others destined to repair the damage caused by these. Nevertheless with the step of the years there are accumulating damages that could not be repaired due to unefficiencies of the system. The mechanisms of repair of damages also are diminishing in effectiveness with which the damages accumulation hastens. Possibly the damages that take place overcome for much the capacity of repair of the organism. The result of all this is that our body becomes less functional as weaker and vulnerable before the illnesses. The first step in this direction seems to be the free radicals creation at a speed and in a quantity that overcomes the aptitude of the body to be liberated of them. To this condition he is met like stress oxidativo. It has been believed that the stress oxidativo contributes to the development of more than sixty such degenerative illnesses like: arthritis, cataracts, cancer, cardiac conditions, problems of the immune system and of the nervous system. The membranes of our cells and much especially those of the brain, they possess a big fats quantity polinosaturadas. This type of fat is very capable to the oxidation producing big quantity of free radicals that possibly damage the cell.                                       

Since we have already indicated our own body it produces several substances destined to join the free radicals and to neutralize them. In the food that we consume also there are well-known substances like antirust that they help in this task. In general terms, the antirust ones work donating electrons with what they prevent the free radicals from stealing them of our cells. For several decades it is known that the vitamins C and E and the Beta Caroteno they possess antirust properties. In the same way it is known that the minerals selenium, zinc, manganese and copper fulfill an important function helping to activate the defenses system against the free radicals of our body. Nowadays, nevertheless, it has been discovered that a good number of food, specially of vegetable origin there possess antirust properties that in several cases are much more powerful than those of the already mentioned vitamins.

One of the results of the process of photosynthesis for which the plants produce his energy is the oxygen liberation. Therefore, the plants also need to be protected from the harmful effects of this one. For this they have developed diverse antirust substances.

An important fact about the antirust ones is that none has the aptitude to control the diverse types of free radicals and products of oxidation that take place in the organism. Antirust some of them take charge of a type of free radical while others take charge of others. Another important fact is that once antirust ride to end his protective work turns also into a free radical. In this moment several things can happen. Antirust other can come in his help and regenerate it, also the antirust one can self-destruct or at the worst it can react with some part of the cell hurting. For this reason many investigators understand that it is not healthy to concentrate in consuming big quantities of antirust one or two but it is important to consume a variety of these.

There exist three principal categories of antirust derivatives of the plants, namely: The carotenoides The flavoniodes or bioflavonoides   The tocoferoles and tocotrienoles.

It notices: The juice and the seed of grenade (Pomegranate) are considered to be three times more beneficial antioxidantemente that the same quantity of green firelighter or it came.
