First, vitamin B, formerly known as vitamin B, is a general term for B vitamins and belongs to water-soluble vitamins. They usually come from the same food source, such as yeast. It is an essential part of metabolism in the body, and each vitamin B participates in key metabolic reactions, usually in the form of coenzyme.
2. Chemical properties: Vitamin B is a water-soluble vitamin, which has synergistic effects in regulating metabolism, maintaining the health of skin and muscles, improving the functions of immune system and nervous system, and promoting the growth and division of cells (including promoting the production of red blood cells and preventing anemia). Among them, vitamins B 1, B6 and B 12 help to protect nerve cells, while vitamin B2 has antioxidant effect, while plants can synthesize vitamin B2, which animals generally cannot, so it is necessary to obtain vitamin B2 from food, which is one of the essential elements to maintain the normal growth of animals. If lacking, it may lead to growth stagnation or local damage.
Third, effective effect: vitamin B can protect the liver of the drinker. The most important nutrients for liver function are not only protein, but also vitamins. Starch is an indispensable nutrient when it is converted into sugar in the liver, and the nutrients are rearranged to synthesize new substances (this is called metabolism); In addition, the liver also breaks down useless substances and toxins. These activities mainly rely on enzymes, and enzymes rely on vitamins when they play their roles. Therefore, when vitamins are lacking, the liver can't work normally.
Fourth, food is abundant.
1. Foods rich in vitamin B 1: wheat germ, pork leg, soybean, peanut, tenderloin, ham, black rice, chicken liver, germ rice, etc.
2. Foods rich in vitamin B2: lamprey, beef liver, chicken liver, mushrooms, wheat germ, eggs, cheese, etc.
3. Foods containing vitamin B6, vitamin B 12 ... Nicotinic acid, pantothenic acid, folic acid: liver, meat, milk, yeast, fish, beans, egg yolk, nuts, spinach, cheese, etc. Vitamin B 1 cannot be stored in human body, so it should be supplemented every day.
4. Another main source of B vitamins is intestinal microorganisms, so in the case of good health and balanced diet, it is generally not lacking. Long-term antibiotic treatment may lead to vitamin B deficiency.
