Antioxidants and free radicals their interaction


Having read through popular literature about the influence of free radicals on the human body, we begin to think that with every breath we need to consume a supplement with antioxidants.


What really happens in the body?

The previous articles describe the origins of free radicals. Free radicals are necessary elements in the process of body’s vital activity.

Their excess brings harm to our bodies. That’s why antioxidant systems urge the neutralization of the destructive action of excess free radicals a in our bodies.

The restoration of the balance is done by special ferments. Glutathione is the most powerful among antioxidants, produced by our body. The quantity of this substance in the cell is so large that it quickly neutralizes the excess of free radicals in the cellsthrough a sequence of reactions.

The body’s antioxidant system prevents autooxidation of the cell’s biological particles.

If the antioxidant system lowers its protection, an excess of free radicals occurs. They cause damage to the cell structures and bring about further destruction of the cells. This is called oxidative stress. During oxidative stress, glutathione becomes active and neutralizes it.

The antioxidant system can’talwaysrestore the balance.

Various factors, which cause the oxidative stress, decrease its efficiency.

This leads to an increasing flow of free radicals that the antioxidant system can’t stop anymore.

1. Ecological situation of the environment air pollution, ultraviolet radiation, drinkable water contamination with pesticides, nitrates, and photochemical smog.

Smog plays an important role in the formation of free radicals.

2. Smog plays an important role in the formation of free radicals. The concentration of nitrous and other harmful substances in the air, sun radiation, and air stagnation brings about the formation of high concentrations of free radicals. These problems occur in big cities. Ecological problems are very harmful for the human body, especially for the respiratory and circulatory systems.

3. The consumption of low-quality foods, containing nitrates, pesticides, carcinogens, alcohol beverages, and smoking increase the formation of an excess of free radicals in the body. This contributes to the formation of poisonous substances, which are generated in the stomach and cause cancer in the organs of the digestive system.

4. With DNA affected (macromolecule, containing a person’s genetic code) by free radicals, the mechanism of hormone production, which controlscell growth and division, is disturbed. This leads to malignant tumors.

5. The effects on the brain cells leads to a decrease in memory and attention span, development of Parkinson's disease, and Alzheimer's disease.

6. With the effects on the circulatory system’s cells, atherosclerosis develops. Oxidative stress is associated with hypertensive disease, lung ailments, and some kinds of cancer.

7. The oxidative stress affects lipids the substances, transferring of energy to the cells, and building of their protective layer, etc. The lipids’ effects cause a chain reaction of the formation of new free radicals. In the presence of cuprum, the chain reaction of free radicals is accelerated and leads to cell destruction.

Free radicals

8. Free radicals destroy the body’s natural antioxidants. These are vitamins, hormones, and other organic elements, protecting the cells from free radicals.

9. Free radicals destroy the membranes gradually, increasing their penetrability. This involves an excessive supply of calcium to the cell. The ratio of calcium and potassium in the heart muscle is imbalanced. The heart work is disturbed as a result.

The oxidative stress can be slowed down, helping the antioxidant system.

The body gets its necessary substances from food. By consuming food products, containing antioxidants, it’s possible to avoid oxidative stress. We want to remind you of the natural antioxidants which promote therestoration of the antioxidant system function.

Ways a person can help himself/herself, lowering the influence of the oxidative stress:

Exclude the consumption of unhealthy food products;

Give up on bad habits;

Improve the environment as much as possible;

Consume products, containing antioxidants, to improve the function of the body’s antioxidant system in the fight against free radicals.
