This summer is wearing tanned skin! Like every summer, in fact, you’re probably thinking about how to get an uniformly tanned skin, to keep your tanned skin as long as possible and how to maintain your skin’s health. I’ll give you a tip: healthy eating will help a lot!
Ultraviolet rays emitted by the sun acts on the epidermis and cause significant biological effects that lead to release of free radicals in the skin cells. But there are molecules capable of capturing free radicals and protect cells against them. It is provitamin A, antioxidant vitamins C and E, zinc, selenium and carotenoids.
Ultraviolet Affect Skin Health
UV rays act on various cellular constituents: proteins, nucleic acids, cytoplasmic membrane, destroying the blood capillaries and fibroblasts. UV-B induce the formation of dimers in the DNA strands. This phenomenon blocks the translation of genetic information and prevent cellular repair, causing metabolic disorders (cellular aging) and possibly disordered cell death or cell proliferation (cancer).
Specifically, the effects are:
- dry skin;
- marked wrinkles;
- loss of skin elasticity;
- pigmentation (solar lentigo);
- atrophy of the epidermis or dehydration.
All these are signs of skin aging caused by UV rays harmful action.
The Beneficial Action Of Foods Rich In Multivitamins
Foods rich in selenium, beta-carotene, vitamin E protects our skin from the sun because it acts against free radicals and increase skin tolerance to UV rays.
Selenium: is a nutrient found in meat, vegetables, seafood, cheese and all foods rich in protein. Protects skin from sun, makes tanning easier and slows skin aging by acting against free radicals. Must be consumed in large enough quantities for the action to be truly effective (equivalent to 200 grams of green vegetables / day). Most adults have selenium deficiency, especially smokers.
Beta-carotene: Carotenoids are natural pigments in fruits and vegetables.
Boosts immunity and helps cell renewal and oppose formation of collagenase, an enzyme that destroys collagen in skin. Beta-carotene is the precursor of vitamin A and is found in carrots, spinach, apricots, peaches, grapefruit.
Vitamin A: the first vitamin discovered (in 1913), is soluble and is absorbed by fat. Prevents skin cancers, promotes healing and helps renew skin cells. Is found in all animal tissues as retinol.
Vitamin C: It is beneficial in the treatment of skin aging prevention. Contained mainly in vegetables and fruits, is present in large amounts in spinach, Brussels sprouts, cauliflower, cabbage, orange, lemon, grapefruit, tomatoes, peaches.
Vitamin E: prevents cellular aging improving skin tolerance to sunlight. Has a complete anti-aging role and acts in synergy with selenium and vitamin C to prevent degradation of essential fatty acids. It is present in nuts, germ of cereals, green vegetables, egg yolk and butter.
