Aggression of cells caused by the massive presence of free radicals in the body, oxidative stress is responsible for an acceleration of aging.
For Dr. Jean-Michel Cohen, they are chemical agents “produced either by our body itself, or by external factors, which enter a cell and cause oxidation”.
The human body “has enzymes to naturally destroy these substances, which are a derivative of oxygen, but when there is too much oxidation, the cell functions much less well, is damaged”, and this causes premature skin aging .
alcohol, tobacco, pollution…
The lifespan of the cells is shortened “because the body will too quickly exhaust all the resources which are used for defense”. To slow down this phenomenon, continues Jean-Michel Cohen, it is necessary “to have a healthy way of life, to eat varied and balanced, and to avoid the consumption of alcohol and tobacco”.
The production of free radicals is also favored by “environmental pollution, exposure to ultraviolet radiation, over-consumption and production of iron, as well as inflammation due to infections”.
The nutritionist doctor points out that vitamins (A, E, and C) act as antioxidants and help neutralize free radicals”. On the other hand, “their function remains less important than the natural defenses of the organism”.
