Vitamins A, C and E are antioxidants. Antioxidants are essential to our health. They protect our body from free radicals (aggressive particles) and therefore decrease the risk of appearance of many diseases.
WHAT IS IT ?
Antioxidants bring together vitamins, trace elements and micronutrients. They are present in our diet. The role of its molecules is the protection of the body’s cells against free radicals.
Free radicals are extremely aggressive particles, made permanently by the body from oxygen. Free radicals are responsible for the aging of our cells.
WHAT IS THEIR ROLE ?
External factors such as pollution, stress, tobacco, UV rays from the sun lead to an increase in the production of free radicals.
When the amount of free radicals in the body is higher than that of antioxidants, it is said that the body is exposed to oxidative stress.
This oxidative stress causes damage to the DNA of the cells. In the long term, it promotes premature aging of the skin, the appearance of cancer, diabetes, cardiovascular disease, macular degeneration and cataract.
The role of antioxidants is the neutralization of excess free radicals in the body to fight against oxidative stress.
