A balanced diet is an essential prescription for healthy and vibrant skin. The good news is that the foods that happen to be good for your skin are also good for your overall health. Many people find that the appearance of aging skin --- wrinkles, thickening, discoloration, and decreased elasticity --- is one of their biggest beauty concerns. While genetics largely determines when your skin starts to show these signs of aging, and the extent to which it shows them, environment damage to your skin, as well as damage you cause yourself through lifestyle choices, can greatly accelerate this process.

Skin damage occurs as a result of oxidation, a chemical process in which unstable molecules called free radicals steal electrons from healthy cells. The most damaging oxidative stressors that we expose ourselves to are smoking and sunlight.

          Vitamin A, which is soluble in fat solvents while insoluble in water, has a heat stable in absence of air and easily destroyed on exposure to air or ultra violet rays. There are two main sources for us to get Vitamin A and they are animal sources and vegetable sources. Cod liver oil, halibut liver oil, milk, butter, eggs and fishes are all included in animal sources. For vegetable sources, we have carrots, spinach, vegetable oils, green leaves, and yellow fruits, etc. For example, you can eat mangoes or tomatoes to generate Vitamin A. Actually, Vitamin A has lots of functions and it is one of the most important nutrition for human’s body as well. Actually, Vitamin A is essential for growth. Since it is a component of rhodopsin, it is also an essential for night vision. Vitamin A helps in the preservation of structural integrity and the normal permeability of membranes. We can use it to maintain our health and activity of epithelial tissues and glands. Preventing infection, maintaining nutrition and functions of the nervous tissue are also two functions of Vitamin A. Besides that, it controls the action of the bone cells, formation and sulphation of mucopolysaccharides, helps in normal fertility and also helps in glucose synthesis by stimulating enzymes concerned. Additionally, if we cannot generate enough Vitamin A for our body, we maybe in the potential of have some effects of deficiency, such as night blindness, Xerophthalmia, Keratinization of skin and mucous membrane with increased susceptibility to infection, retardation of growth in children and defective growth of bone and teeth. Obviously, Vitamin A is very much important to human beings, but how much we should get every day? In fact, for most of adults, we need 5000 i.u. for daily requirement. For growing children and during puberty, lactation and pregnancy, they need 6000 to 8000 i.u. every day.
