Vitamin B is a general term for B vitamins, which often come from the same food source, such as yeast. It belongs to water-soluble vitamins. There are mainly vitamin B 1 (thiamine, a vitamin for treating beriberi), vitamin B2 (riboflavin), vitamin PP (nicotinic acid or nicotinic acid, a vitamin for treating furuncle), vitamin B6 (pyridoxine, an anti-dermatitis vitamin), pantothenic acid (pantothenic acid), biotin, folic acid and vitamin B1.
There are more than twelve kinds of B vitamins, and nine kinds of vitamins are universally recognized as essential for human body, all of which are water-soluble vitamins. They only stay in the body for a few hours and must be replenished every day. B group is an essential nutrient for all human tissues and the key to the release of energy from food. They are all coenzymes, which participate in the metabolism of sugar, protein and fat in the body, so they belong to one family.
All vitamin B must play a role at the same time, which is called VB fusion. When a certain VB is ingested alone, due to the increase of cell activity, the demand for other VBs increases, so the functions of various VBs are complementary, which is the so-called "Kanekin's Law". Dr Roger William pointed out that all cells have exactly the same demand for vitamin B.
B vitamins closely related to skin care are B 1. B2.B3.B5.B6 and h, etc. Vitamin B 1, also known as thiamine, can inhibit cholinesterase activity, reduce skin inflammatory reaction, prevent and treat seborrheic dermatitis and eczema, and improve skin health. Mainly from cereals, fresh vegetables, fruits, milk, egg yolk, lean meat, liver, yeast, bran, peanuts and so on. Vitamin B2, also known as riboflavin, is involved in the redox reaction of cells, the synthesis of hemoglobin and the metabolism of sugar, protein and fat, which can help the skin to resist the damage of sunlight and promote cell regeneration. When the human body lacks vitamin B2, the skin is sensitive to sunlight, and solar dermatitis is easy to occur. Exposure to the sun for a long time, the face is red and itchy, and powder appears around the nose. Mainly from egg yolk, milk, yeast, green leafy vegetables, rice bran, germ, animal liver and kidney, carrots, brewing yeast, fish, oranges, oranges and so on. Vitamin B3, also known as nicotinic acid, can inhibit the formation of melanin and prevent rough skin. Conducive to the recovery of damaged cells or skin. It plays an important role in maintaining the integrity of normal tissues, especially skin, digestive tract and nervous system. Vitamin B6 is closely related to skin health and is a part of the molecular structure of many enzymes and auxiliary enzymes. Promoting amino acid metabolism to maintain skin health can reduce capillary wall permeability and hyaluronidase activity, reduce allergic reaction and inflammatory reaction, and promote epithelial cell growth. Can be used for preventing and treating pachylosis, acne, sunburn, itching relieving and tanning, and can also be used for preventing and treating seborrheic skin inflammation, acne, seborrheic dermatitis, eczema and desquamation skin changes. Mainly from liver, egg yolk, grain, germ, beans, milk, fish, meat and vegetables. Vitamin H, also known as biotin, can promote skin metabolism, improve rough skin, and prevent alopecia, seborrheic dermatitis and acne multiforme. It exists in liver, egg yolk, milk, yeast and other foods.
B vitamins participate in DNA synthesis, maintain genome stability, assist DNA repair, and regulate cell proliferation and death, thus playing an anti-cancer role.
Vitamin e can promote reproduction. It can promote the secretion of sex hormones and increase the vitality and quantity of male sperm; Increase the concentration of female estrogen, improve fertility and prevent miscarriage. When vitamin E is deficient, testicular atrophy and epithelial cell degeneration will occur, leading to abnormal pregnancy. Vitamin E is often used to treat threatened abortion and habitual abortion in clinic. In addition, it is also helpful to prevent male infertility.
Other functions include protecting T lymphocytes, protecting red blood cells, resisting free radical oxidation and inhibiting platelet aggregation, thus reducing the risk of myocardial infarction and cerebral infarction. It also has a good curative effect on burns, frostbite, capillary bleeding, menopausal syndrome, beauty and so on. It is also found that vitamin E can inhibit the lipid peroxidation of lens, dilate peripheral blood vessels and improve blood circulation.
Foods rich in vitamins and minerals can form a balanced diet, while vitamin E represents an excellent antioxidant effect and challenges the age. Vitamin e can effectively fight free radicals, inhibit the production of lipid peroxide and eliminate chloasma; Inhibit tyrosinase activity, thereby reducing melanin production. Esterified vitamin e can also eliminate excessive oxygen free radicals caused by external factors such as ultraviolet rays and air pollution, and play a role in delaying photoaging, preventing sunburn and inhibiting the formation of sunburn. Increasing the intake of vitamin E is very simple, and a plate of fresh asparagus is enough.
Vitamin E is a fat-soluble vitamin, so a certain amount of fat is needed to prevent it from being digested. Nuts are the perfect snack. Almonds and hazelnuts are rich in vitamin E and beneficial fat, which can protect your cell membrane from oxidation to some extent.
Oily foods, such as red palm oil and olive oil, are rich in vitamin E. Therefore, in order to increase your red blood cell count, choose these healthy and delicious oils when cooking.
Many foods contain vitamin E, which forms the epidermis of many fruits and vegetables, especially green leafy plants such as spinach. Of course, avocado is also very rich in vitamin E.
