How do they functions? What are they?
Free radicals are unstable compounds mainly formed of oxygen. They are generated during the normal functioning of the body, but their production can be increased by pollution, cigarette smoke or prolonged exposure to the sun, for example. Their chemical structure causes them to damage other atoms by “oxidizing” them. They are however more or less kept in check by the body’s natural antioxidants. However, certain factors can upset this balance. If free radicals exceed the body’s ability to neutralize them, they can contribute to the development of several diseases, including cardiovascular disease, certain types of cancer and other diseases associated with aging.
Before understanding the usefulness of antioxidants, we must know the role of free radicals in our body. Free radicals are unstable molecules that our body produces in small quantities through the oxygen we breathe.
Free radicals are very reactive. In small quantities, they participate in the fight against viruses and bacteria. In excess, they accelerate the deterioration of cells. Factors like air pollution, tobacco, aging and even sunlight favor their synthesis, this is called “oxidative stress”. As a result, we become vulnerable to many diseases such as cardiovascular disease, diabetes, eye disease, cancer and Alzheimer’s disease. The most visible effect of an overproduction of free radicals is the aging of the skin.
Antioxidants come into action when the number of free radicals in our body is too high. Their job is to counter, decrease and inhibit the action of free radicals. Thus, the adoption of a diet rich in antioxidants helps to stay healthy and fight against the diseases mentioned above.
The foods richest in antioxidants are:
- Red fruits (blueberry, strawberry, raspberry, etc.)
- Nuts (pecans, hazelnuts, etc.)
- Citrus fruits (orange, grapefruit, lemon, etc.)
- Green vegetables (spinach, artichoke, broccoli, etc.)
THE DIFFERENT TYPES OF ANTIOXIDANTS
There are many substances that can act as an antioxidant. The best known antioxidants are:
- Vitamin E
It helps cells to regenerate. It’s a great anti-aging product.
- Vitamin C
Vitamin C is a particularly powerful antioxidant to defend our immune system. It helps fight colds. It is also involved in the formation of collagen (gives elasticity and resistance to the skin).
- Vitamin A
Vitamin A plays a decisive role in vision. It is also essential in bone growth, the conditioning of skin cells and the regulation of the immune system.
Selenium activates the antioxidant enzyme in our body: glutathione peroxidase. Together with vitamin E, it protects cells against premature aging.
Zinc promotes scarring of the skin. It also acts on the endocrine system, respiration, respiration and fitness.
Polyphenols are flavonoids capable of protecting our body against cardiovascular disease.
All women whose skin begins to show signs of aging, from 45-50 years of age.
- People who, from the age of 30, want to take preventive action to limit the impact of free radical attacks on a daily basis.
- All those who are very exposed to pollution, who work outside, live in the sun, those who smoke …
- Women aged 50 and over who wish to use a long-acting deep-acting anti-aging product without the risk of irritation
