Two groups of nutrients that are essential to having healthy skin are vitamin A and healthy fatty acids.
Vitamin A is available as straight vitamin A, found in animal foods, and as carotenoids, which are plant-based nutrients that can be converted to vitamin A in healthy individuals.
Skin is made of specialized epithelial tissue, and the health of epithelial tissue is directly dependent on the amount of vitamin A that we get from our diet. When obtained through healthy food choices, vitamin A can help resist infection, prevent wrinkles, and keep skin looking youthful.Food sources of Vitamin A are cheese, eggs, oily fish (such as mackerel), milk and yoghurt.Liver is also a rich source of vitamin A.
Healthy fatty acids are essential to skin health for a number of reasons, one of the most important ones being that vitamin A and carotenoids are fat-soluble nutrients that are most efficiently absorbed into the bloodstream in the presence of healthy fats.Healthy fatty acids are basically divided into two categories-Essential fatty acids and Non-essential fatty acids.
Examples of Essential fatty acids are Omega-3 fatty acid(Linolenic acids) found in food sources like Flaxseed oil, flaxseeds, hempseed oil, hempseeds, walnuts, pumpkin seeds, Brazil nuts, sesame seeds, avocados, some dark leafy green vegetables, canola oil, soybean oil, wheat germ oil, salmon, mackerel, sardines, tuna,etc and Omega-6 fatty acids(Linoleic acids) found in Flaxseed oil, flaxseeds, flaxseed meal, hempseed oil, hempseeds, grapeseed oil, pumpkin seeds, pine nuts, pistachio nuts, sunflower seeds (raw), olive oil, olives, evening primrose oil, black currant seed oil, chestnut oil, chicken,etc.Example of
non-essential fatty acid is Omega-9(Oleic acid) which is found in Olive oil (extra virgin or virgin), olives, avocados, almonds, peanuts, sesame oil, pecans, pistachio nuts, cashews, hazelnuts,etc.
