What kind of vitamins should normal people eat?

The physiological functions of vitamin A are mainly to maintain visual function under dark light, protect epithelial function, promote the normal development of bones and teeth, and maintain normal immune and reproductive functions. When vitamin A is deficient, the liver stores are first transported to the blood, and the liver reserves are depleted, so that the serum vitamin A is reduced. Clinical symptoms do not appear until serum vitamin A is very low.

The adaptability of the eye is reduced, that is, night blindness and dry eye, dry conjunctiva of the eye, 1' white light, and in severe cases, the cornea is dry, ulcers, perforation, iris prolapse and even blindness. **There may be follicular keratosis that looks like a goosebump. The respiratory tract and urinary tract are prone to secondary infection, and infants and young children may have physical development delay.

Before the liberation and the early days of liberation, it was very common for children in China to suffer from severe vitamin A deficiency, especially in the summer and autumn after children suffering from chronic diarrhea or dysentery, often blindness on one or both sides, which is almost impossible to see now, mostly for the reduction of serum vitamin A, but no clinical symptoms. According to a survey conducted by Beijing, about half of all age groups are deficient in serum vitamin A. The vitamin A content in milk is insufficient, and children need it.

If the cow's breastfed infants are not supplemented with vitamin A drops, 1 3 1 2 serum vitamin A is insufficient. Therefore, the cow's breastfed infants should be supplemented with vitamin A1 500 IU daily, or fortified with vitamin A fresh milk, so that vitamin A 2000 IU liters are contained, after a survey in Beijing, the daily diet of this fortified milk more than 500 ml, serum vitamin A is mostly normal, the effect is very good. or fortify an equivalent amount of vitamin A into infant formula.

Because the vitamin A content in breast milk is often insufficient, it is best for breastfed infants to supplement vitamin AD drops appropriately, pay attention not to exceed the physiological requirements, and add complementary foods on time.

Excessive intake of vitamin A can cause vitamin A toxicity, a single intake of vitamin A 30,000 IU or more, can cause acute poisoning within a few days, mainly symptoms of increased intracranial pressure, such as vomiting, anterior fontanelle bulge, cranial suture dehiscence, etc., after stopping vitamin A, the symptoms disappear quickly. Daily intake of tens of thousands of IU of vitamin A can cause chronic poisoning after a few months, such as irritability, loss of appetite, and metastatic bone pain in the limbs with soft tissue swelling. There may also be symptoms of increased intracranial pressure, itching, dry hair, bleeding, etc.

In severe cases, there may be skeletal deformities that cause claudication due to the different lengths of the legs.

Vitamin A poisoning is mostly caused by a single or continuous daily intake of a large amount of concentrated cod liver oil or concentrated vitamin AD drops. Polar bear liver contains the largest amount of vitamin A, which can cause vitamin A poisoning after eating. The liver is an organ that stores vitamin A, which is rich in nutrients, but it should not be eaten every day.

Children's food should be varied.

Eat more vegetables, tomatoes, rape, celery, apricots, peaches, plums, oranges, jujubes, lean meat, egg yolks, animal liver, kidneys, etc., because the iron in food is not easy to absorb. Therefore, vitamin E should be taken at the same time.

Eat well, rich in vitamins and minerals.

Every kind of vitamin needs to be supplemented! But more is better!

Go to the pharmacy for 21 gold vita or Shancun to eat.

Vegetarian B includes vitamin B1, vitamin B2, vitamin B6, vitamin B12, niacin, pantothenic acid, folic acid, etc. These B vitamins are indispensable for promoting metabolism in the body and converting sugars, fats, proteins, etc. into calories. If vitamin B is deficient, cell function is immediately reduced, causing metabolic disorders, and the body will experience sluggishness and loss of appetite.

On the other hand, drinking too much alcohol can lead to liver damage, which in many cases goes hand in hand with vitamin B deficiency.

The following are foods that are rich in vitamin B:

Foods rich in vitamin B1: wheat germ, pork leg meat, soybeans, peanuts, muscle, ham, black rice, chicken liver, germ rice, etc.

Foods rich in vitamin B2: eel, beef liver, chicken liver, shiitake mushrooms, wheat germ, eggs, cheese, etc.

Foods containing vitamin B6, vitamin B12, niacin, pantothenic acid and folic acid: liver, meat, milk, yeast, fish, legumes, egg yolks, nuts, spinach, cheese, etc. Vitamin B1 cannot be stored in the body, so it should be replenished daily.

It is difficult to consume all B vitamins, but it is easy and convenient to consume them by choosing foods carefully. The above foods containing B vitamins can be divided into two groups. If you look at the above classification, you can see that and all of them are contained in roughly the same foods.

Therefore, as a group of foods, and together to form a group of foods, and the combination of two groups of foods, you can basically get the B vitamins in your hands.

It is safer to supplement vitamins through food. Of course, you can also supplement vitamins through health products, and the types of vitamins are relatively comprehensive.

Is this question easier! I'm telling you, if it's a health care product, it's definitely pine pollen! It's called a plant nutrient bank! If it's food, it's tomatoes and oranges! You try it!

1. Vitamin A:

Vitamin A, also known as retinol and anti-dry eye, has the functions of maintaining normal visual function, maintaining the health of **symptoms, and promoting immunoglobulin synthesis. Vitamin A is mainly found in foods such as eggs, cod liver oil, etc., and you can also eat more foods rich in -carotene, such as carrots, mangoes, pumpkins, etc., -carotene can be converted into vitamin A in the human body.

2. Vitamin C:

Vitamin C is one of the essential vitamins for the human body, it is a water-soluble vitamin, vitamin C has an antioxidant effect, which can remove excess free radicals in the human body; In addition, vitamin C is also an important component of collagen synthesis, and vitamin C deficiency may also lead to anemia in people. Vitamin C is mainly found in fresh vegetables and fruits, such as kiwifruit, tomatoes, citrus, etc., when the human body lacks vitamin C, you can also directly eat vitamin C tablets, which is more convenient and effective to supplement.

3. Vitamin B group:

The B vitamins are a large family that has a multifaceted effect on the human body. B vitamins are the most susceptible to the fact that they are most susceptible because they are the most susceptible to sugar because they are the most energy required by the body's muscles and nerves.

In addition to the above vitamins, the human body needs to supplement vitamin E, vitamin D and so on. In addition to supplementing essential vitamins through food, you can also directly take vitamin tablets to supplement at the same time.

What vitamins should be supplemented by the human body depends on what vitamins your body lacks, what vitamins can be supplemented, and vitamins can not be supplemented indiscriminately.

The vitamins you need to supplement regularly are B1B2 VC, which is commonly used, and the combination of the three of them, together with some calcium tablets, is good for the health of the human body to enhance their immunity.

The normal growth and development of the human body needs various vitamins, so if you want to supplement vitamins, it is best to choose a variety of vitamins, such as 21 gold vitamin, similar to this vitamin supplement is better.

What vitamins should be supplemented by the human body is good for the human body, and I think that supplementing vitamins in general is terrible, depending on what you want to supplement vitamins, selenium and multivitamins. Or the third force, everything needs to be supplemented, and you should eat more fresh fruits and vegetables.

I think it's better for the body to supplement vitamin C and B vitamins.

Which vitamins are better for the human body to supplement depends on your physical fitness, and you can't just make up for it.

Vitamins are found in food in the form of provitaminostats;

Vitamins are not components of the body's tissues and cells, and it does not produce energy, its role is mainly to participate in the regulation of the body's metabolism;

Most vitamins cannot be synthesized by the body or are not synthesized in sufficient quantities to meet the needs of the body, and must be obtained frequently through food;

The human body's need for vitamins is very small, and the daily requirement is often calculated in milligrams or micrograms, but once the deficiency is deficient, it will cause corresponding vitamin deficiencies and cause damage to human health;

Unlike carbohydrates, fats and proteins, vitamins account for only a very small proportion of natural foods, but they are necessary for the human body. Some vitamins such as "Vitamins" can be synthesized by bacteria in the intestinal tract of animals, and the amount synthesized can meet the needs of animals.

Animal cells can convert tryptophan into niacin (a B vitamin), but the amount of production is insufficient; Vitamin C can be synthesized by other animals except primates and guinea pigs. Plants and most microorganisms can synthesize vitamins on their own and do not need to be supplied from outside the body. Many vitamins are components of coenzymes or coenzymes.

The lack of vitamins in the human body can lead to the occurrence of some diseases. Vitamin A deficiency, easy night blindness. Vitamin C deficiency can lead to fractures or scurvy.

Vitamin D deficiency can cause diseases such as high blood pressure and cardiovascular disease. Lack of vitamin B1 and B2 can easily cause digestive and nervous system disorders, stomatitis, and dermatitis. There are also many foods that contain a lot of vitamins, such as:

Apples, watermelon, broccoli, spinach, meat, eggs, soy products, dried fruits, animal liver, milk, cod liver oil, etc., can be a good vitamin supplement.

The thirteen essential vitamins include four fat-soluble vitamins and nine water-soluble vitamins. Vitamin is a low molecular weight organic compound that cannot be synthesized and synthesized in very little amount in the human body, cannot meet the needs of the body, and must be supplied by food to maintain normal life activities. Vitamins are not components of the body's tissues, nor are they energy donors, but they play an extremely important role in regulating the metabolism of human substances and maintaining normal physiological functions, and are essential nutrients.

Fat-soluble vitamins include vitamin A, vitamin D, vitamin E, and vitamin K. In addition to being directly involved in influencing specific metabolic processes, most of them also bind to cell core receptors to affect the expression of specific genes.

Fat-soluble vitamins are hydrophobic compounds that can be dissolved in fats, are often absorbed with lipids, and are transported in the blood in combination with lipoproteins or specific binding proteins, and are not easily excreted. It is mainly found in the liver in the body, so it does not need to be supplied daily. Water-soluble vitamins include B vitamins, including vitamins B1, B2, PP, B6, B12, biotin pantothenic acid and folic acid, and vitamin C and lipoic acid.

Water-soluble vitamins mainly constitute cofactors of enzymes in the body, which directly affect the activity of enzymes. Water-soluble vitamins depend on food, and excess water-soluble vitamins in the body can be excreted in the urine, and they are rarely accumulated in the body, and no poisoning occurs, but insufficient donors often lead to deficiency.

The human body is a delicate instrument, and if you want to maintain the normal operation of this instrument, you need a reasonable combination of a variety of nutrients, and although vitamins only account for a small part of them, vitamins A, B, and C are more important.

Under normal circumstances, as long as the human body is not partial to eating, there is no need to supplement any additional vitamins, if there is a picky diet, such as those who love meat and do not like to eat fruits and vegetables, then buy a box of multivitamins and take them according to the above dose. If you only eat vegetables and fruits and don't eat meat in order to **, you have to supplement some protein powder.

There are two main types of essential vitamins for the human body, one is fat-soluble vitamins and the other is water-soluble vitamins. There are four types of fat-soluble vitamins: vitamin A, vitamin D, vitamin E, vitamin K; There are nine types of water-soluble vitamins:

Vitamin B1, vitamin B2, vitamin B6, vitamin B12, folic acid, pantothenic acid, biotin, niacin (niacin comes in two forms: niacin and niacinamide), and vitamin C. Vitamins directly affect the absorption and metabolism of the human body, and once deficient, it can lead to related diseases.
