As I grew up, Easter was the second best thing after Christmas. The best part was searching for and collecting painted eggs, laid in nests of twigs and moss, throughout our garden by the "Easter bunny" (my mother). After I had found them all I got my Easter-egg, packed with candy, and all was bliss.
Easter is special to many, and celebrated differently, country to country, family to family, but I dare say, eggs are always part of the tradition.
I like looking into foods for the skin, and as such, what better time than this to have look at the skin-benefits of eggs? So here you go, the 7 major reasons to have an egg a day, this holiday.
1. Amino Acids
Proteins are the building blocks of our body, and aminoacids are the subunits making up each protein. There are 20 known aminoacids, and one egg contain 18 of those. That's pretty amazing! Aminoacids are especially important for skin, hair and nail health.
Most importantly, Creatine plays an important role for healthy skin. Creatine provides the cells with energy and thereby supports the regeneration of connective tissue, cells and metabolism of the skin. Creatine stimulate cells to produce more collagen and elastin. Also, cells which are supplied with creatine are capable of repairing damaged DNA. Creatine is produced from the amino acids arginine and methionine, both of which are found in eggs.
Selenium boosts immune system function, which can help ward off skin infections. One of the most important functions of selenium is as a component of glutathione peroxidase, an enzyme necessary for the antioxidant function of glutathione. Glutathione is one of the major antioxidants in the body that protects against cellular damage from the free radicals that cause inflammation, aging, and promote skin cancer. The selenium in eggs may also decrease your risk of skin cancer. -link
Selenium-dependent glutathione peroxidase and its effects on glutathione activity may also have a significant role in acne severity.
3. Vitamin A
One egg contains 270 IU of vitamin A; you need 3,000 IU of vitamin A each day. The vitamin available in eggs provides a number of benefits for your skin, starting with its influence on cellular reproduction. This vitamin encourages your cells to reproduce normally instead of forming abnormal clumps that can develop into moles and skin tags. Vitamin A may also prevent acne breakouts. Read my post about Retinol (vitamine A) here.
4. Vitamin E
This essential nutrient is well known for its role as a chain-breaking antioxidant, protecting cell membranes against oxidative-stress (free radical damage). Vitamin E concentrations in skin can be increased with oral or topical delivery, and are decreased with UV exposure. Clinical trials suggest that dietary as well as topical vitamin E may act as a photoprotectant with the aid of other antioxidants. Read more about eating antioxidants and skin-health here.
5. Vitamin D
Vitamin D is involved in several pathways that maintain health and beauty. I've mentioned some of those ways in my post about the sun and skin, here.
Vitamin D increase moisture levels in skin, protect against UV-damage, and up-regulate "anti-aging" - genes.
6. Pantothenic acid (vitamin B5)
The research of Leung et.al, showed that high doses of vitamin B5 resolved acne and decreased pore size.
A study in 1999 showed pantothenic acid has an effect on wound healing in vitro. Cell proliferation or cell multiplication was found to increase with pantothenic acid supplementation. A more resent publication highlighted the cell proliferative effect pantothenic acid had on skin cells, and collagen directly and through the induction of Keratinocyte (skin-cell) growth-factor.
