Our body is daily exposed to free radicals - atoms or molecules with their action may lead to especially serious consequences. Factors leading to their generation are numerous: exposure to radiation - sunlight or X-ray, tyutyunov smoke, automobile emissions and last but not least - food.
Free radicals are normally present in our body, each of them there for only a fraction of a second, but injuries are left behind, are irreversible. These particles lead to damage of cell membranes, DNA molecules, becoming a major cause of the aging process of the cell.
The presence of free radicals potentiates the occurrence of pulmonary, cardiovascular and neoplastic diseases. It is believed that in every cell of your body daily produce about 10,000 free radicals. People in the menu are often present foods rich in antioxidants, less sick and have relatively good resistance, ie the consumption of these healthy and nutritious products is the best preventive measure against the effects of hazardous particles.
They are a group of elements that protect human cells from the detrimental effects of free radicals, which can significantly impair our immune system. From a chemical point of view, an antioxidant is any substance which, although in much lower concentrations than those of oxidizable substrate significantly delays and / or inhibit its oxidation. In a broader sense to the word antioxidants can be added all the factors that delay or prevent oxidative damage to biological structures.
Our body also has its own antioxidants (coenzyme Q10, glutathione, etc.). That effectively fight the free radicals. But unfortunately due to age, the adoption of uniform and inferior food and continuously increasing negative factors (smoke, fumes, chemical contaminated food and water), quantity and effectiveness of antioxidants decreases inversely to the activity of radicals.
This means only one thing - to increase consumption of foods rich in vitamin C and E, beta-carotene and selenium - or one of the best antioxidants that not only will inactivate free radicals, but also improve the body's physiology, it protect against viruses, bacteria and toxic substances.
Protective antioxidant mechanisms of the body may be divided broadly into three levels:
At the first level including all factors which prevent the endogenous formation of free radicals, so-called preventive antioxidants (transferrin, ferritin, hemosiderin, lactoferrin, albumin).
The second and primary level of protection in the body provides tracking and disposal of already formed free radicals, making them particles or radicals with low reactivity. This is done by enzymes and antioxidants. To relate superoksidizmutazata enzyme, catalase, glutathione peroxidase and glutathione reductase.
Antioxidants can be divided into two groups: lipo-and water-soluble. Belong to the first fat-soluble vitamins - vitamin E (mainly α-tocopherol and γ-tocopherol to some extent) and carotenoids (mainly β-carotene). To water-soluble antioxidants belong vitamin C, thiol compounds and flavonoids. To the third level of protective enzymes are classified, partly recovering from damage caused by free radicals. Such activity occurs as phospholipase A2, some proteolytic enzymes reparative enzymes to DNA and others.
Here is a list of some of the most popular antioxidants:
Petolistna Ginostema
Resveratrol
Lycopene
Pycnogenol
Acai Berry
Blackberries
Lactoferrin
Cocoa
Raspberries
Alpha lipoic acid
Melatonin
Coenzyme Q10
Blue-green algae
Dried fruit
Cat's Claw
Grapes
Ginkgo Biloba
Pomegranate
Spirulina
Red wine
Recent research suggests that their beneficial effect is increased when used together. This raises the question: "Is it possible to create superantioksidant that effectively protects all cells from degeneration?" And the answer would likely be positive. And this is because all these ingredients can be combined in an appropriate way to create a product that would be extremely useful in:
active or passive smoking;
daily moderate to high exposure to air pollution, automobile emissions, work in an environment with high concentrations of toxins, etc.;
overexposure to sunlight;
negative effects of congestion;
increased risk of cardiovascular, liver, degenerative and neoplastic diseases;
in the first trimester of pregnancy to reduce the risk of congenital abnormalities and urodstva;
prevention for all people who wish to slow the aging process and keep your body healthy, even after the age of 60 years of age;
to maintain a young, strong, resilient and good looking skin and reduce wrinkles.
All of us is a known fact that the consumption of foods such as blueberries, broccoli, pomegranates, citrus fruits, and intake of coffee and green tea is extremely useful and desirable phenomenon for a healthy diet. But hardly any of us suspect that sometimes it is potentially a health hazard to the body.
Although the addition of antioxidants in different foods and drinks is more recent, study of American scientists from the University of Kansas shows that daily intake of such products with high content of antioxidants (like vitamin C and E) can cause dangerous and unwanted changes in somatic cells of the human body, which significantly increases the risk of tumors and cancers.
Scientists observed how the increased flow of oxygen to the cells affected their functioning. In their antioxidant and prookislitelen balance is extremely sensitive and even a small decrease or increase may be appropriate negative consequences.
The BBC quoted an American specialists who argue that: "unreasonable overdose of antioxidants can only do harm. Even at first glance may sound absurd, excessive quantity of substances with antioxidant properties has increased, but decreased the body's ability to carry oxygen to cells and this violates the key signaling mechanisms in the human body, necessary for its proper functioning.
The authors of this experiment believe that high doses of antioxidants affect the activity of certain enzymes involved in correcting errors in the DNA chain, resulting from the process of cell division. The study confirms the hypothesis that large doses of antioxidants may be the cause of errors in the genetic code of the cell and generate mutations. For its part, the errors in the DNA material is a prerequisite for the development of tumors and a number of cancers.
Therefore, before proceeding to the use of nutritional supplements containing antioxidants, it is necessary to prove that the body really feels the need of them, which means that it is obligatory not only consultation with a specialist, but it is important and what kind of life leads relevant person.
On the other hand, lack of antioxidants means certain prerequisites for the development of chronic viral and infectious diseases and premature signs of aging, and also increased the pace of development of degenerative eye diseases such as cataracts. Which means that it is necessary to strike the right balance to be the most efficient intake of antioxidants. A reception that combined with a healthy lifestyle will enable you to be in good shape even in old age.
