Vitamins( A, B1)
Vitamin A .Beta-carotene is one of the forms of the existence of vitamin A.
One of the main uses of vitamin A is the stimulation of numerous immune processes, while it provides protection of the body at the cellular level, contributing to the production of different antibodies, etc. Vitamin A also has a positive effect on vision, preventing "night blindness" and various problems with the skin( rashes, etc.).In addition, it is used in the treatment of gastric ulcers, protects the body from various contaminants and the development of cancer cells. Vitamin A is important in the formation of teeth and bones. In addition, vitamin A slows down the aging process, improving the digestion of the body's protein.
A day is recommended to consume 1,000 micrograms of vitamin A.
Beta-carotene is found in dark greens, as well as yellow vegetables. The daily dose of beta-carotene is 6000 mcg, since six units of beta-carotene make up one unit of vitamin A.
Vitamin A is excreted out of the body with difficulty, and therefore prolonged intensive use of it leads to its accumulation and in many cases to poisoning or "hypervitaminosis".
Vitamin B1 .Thiamin in the body quickly forms thiamine pyrophosphate, coenzyme, which takes part in some important steps associated with the Krebs cycle, such as converting pyruvate to acetyl-coA, and reactions in the Krebs cycle itself. In addition, thiamine pyrophosphate plays an important role in the transmission of nerve impulses, improves metabolism, participates in the formation of fatty tissues and carbohydrate metabolism. It also improves energy exchange, affects the elimination of growth problems, increases the ability to learn. In addition to all of the above, it is necessary for the normal operation of the muscles of the esophagus, stomach, and also the heart muscle.
A lack of thiamine can lead to symptoms such as loss of appetite, the appearance of fatigue, depression, nausea, irritation and constipation. Sometimes this can cause the development of beriberi disease. For today, the lack of vitamin B1 is extremely rare. It can be found mainly in alcoholics and people at very low calorie diet. The dose of vitamin B1, which is recommended to be consumed per day, is from 1 to 1.5 mg.
Taking various antibiotics and oral contraceptives can have a bad effect on the level of thiamine in the body.
