Tell me what you eat and I’ll tell you how your skin will age! Indeed, what you put on your plate has visible consequences on your skin and on its capacity to fight or not against the signs of ageing.
Oxidative stress, glycation and skin ageing
These two phenomena, caused by an unbalanced and unvaried diet, have a real impact on skin ageing.
Indeed, oxidative stress causes a reduction in the amount of collagen, elastin and hyaluronic acid produced in the dermis which entails the formation of wrinkles. The skin cells deteriorate and die without being renewed as quickly as required. The result: dark spots quickly appear. Oxidative stress arises when you eat too much red meat, charcuterie and processed food (industrial products that are high in salt, based on refined flower and having lost their nutrients). One must also include raw milk cheeses, burnt food, fried food and grills as well as alcohol.
Nutrition is the main cause of the phenomenon of glycation, the alteration of proteins which, within the skin, causes a loss of suppleness, skin sagging and the formation of wrinkles. This is also caused by the excess of red meat and charcuterie. To that we must add sugary products (desserts, drinks…)
You understand that the fight against free radicals is essential to keep beautiful skin for as long as possible, because by attacking the heart and the membrane of the skin cells, these destroy the skin and stop it from regenerating. Anti-oxidants are excellent anti-ageing combatants, but as the body does not produce enough, you must provide them by eating lots of fruits, vegetables (the most colourful are particularly good for the skin) and pulses (lentils, chickpeas, kidney beans…).
Vegetable oils, oily fish and nuts (peanuts, hazelnuts and almonds…) rich in fatty acids that are « polyunsaturated », promote the increase and the regeneration of the skin, which it protects from free radicals. Also known as Omega-3 and Omega-6, the fatty polyunsaturated acid reinforces the lipidic layer of the epidermis and helps good hydration. They also promote the synthesis of collagen, which maintains the elasticity of the skin.
