What is the best amount of fresh milk for normal children every day?

Children grow fast when they drink milk.

Infant is the most important stage of a person's life growth and development, with rapid growth, vigorous metabolism and high requirements for nutrition. However, infants and young children have weak digestive ability and limited ability to absorb food nutrition, so they need to eat foods that are easy to digest and absorb and rich in nutrients. Milk, such as human milk, goat milk and dairy products, is the best food for babies in this period. If milk food can be adequately supplied, it will certainly lay a foundation for the healthy body and good intellectual development of babies in the future. Babies mainly eat human milk or milk in their early days, but many families in China cut off human milk when their children were about three years old, which seriously affected their growth and development. You know, after the age of three, children's activity increases, their heat consumption increases, their bodies grow fast, their brains and sperm cells develop rapidly, and their nerve fiber branches accelerate their elongation. For example, the weight of a newborn's brain is 25% of that of an adult, which doubles at the age of ten months, triples at the age of two and a half, and reaches 90% of that of an adult at the age of four. Height and weight are increasing, limbs are growing faster, and teeth are changing, so the demand for high-quality minerals such as fat, protein, calcium, phosphorus and vitamins is also increasing. Children must be provided with enough high-quality nutrients to meet the needs of their growth and development. Milk food, especially milk and dairy products, is the best nutritious food for babies. So we advocate that children should insist on drinking milk every day.

Milk can provide children with high-quality fat, which not only produces high heat, low melting point, small fat globules, is easy to digest and absorb, can give children enough heat energy and various fatty acids, but also has the milk flavor that children like.

Milk contains the best protein, which is completely high-quality protein. Protein in milk has special physiological functions, which is especially beneficial to children's growth and development. It is the basic substance that constitutes various cells, tissues and organs of children, and contains all essential amino acids needed by children. Albumin, casein and globulin in milk are necessary for children. If you insist on drinking 250g of milk every day, children can get 7-8g of high-quality protein.

Lactose in milk is absolutely indispensable for babies. It mainly supplies heat energy, which is the driving force for children's growth, development and activities. It is also found only in milk, especially for the development and perfection of children's brain and nervous system, which can promote the absorption of calcium. Lactose can only be obtained by eating milk.

Milk is also rich in minerals such as calcium and phosphorus, which are necessary for the growth and height of children's bones and teeth at this stage. Drinking 300 grams of milk every day can get 360 milligrams of calcium, which can meet most of the calcium needs of infants.

Milk also contains all kinds of vitamins that babies need, so milk is called "the closest complete food". Milk is the best nutrition for children. Children should drink milk or dairy products l-2 times a day. According to the child's growth, age, physique and nutritional status, it is better to drink 250-500 grams of fresh milk every day, and stick to it for a long time, especially after the child is weaned, and continue to eat milk and dairy products to form the habit of eating milk and enjoy dairy products for life.

Ten wrong ways for children to drink milk.

Milk is an indispensable food in people's lives. It is cheap and convenient to eat, but if you "drink it after cooking", you will make some "take it for granted" mistakes, which will greatly reduce the nutritional value of milk.

1. The thicker the milk, the better.

Some parents think that the thicker the milk, the more nutrition their children get, which is unscientific.

The so-called concentrated milk refers to adding more milk powder and less water to milk, so that the concentration of milk exceeds the normal proportion standard. Some parents are afraid that fresh milk is too weak, so they add milk powder to it. In fact, the intensity of milk for infants should be directly proportional to their age, and its concentration should be gradually increased according to their age. Even for newborns within 1 month, the proportion of mixed water in milk should be gradually reduced according to the digestion situation. If babies often eat thick milk, it will cause diarrhea, constipation, loss of appetite and even refuse to eat. Over time, the weight will not increase, but also cause acute hemorrhagic enteritis. This is because the organs of infants and young children are delicate and cannot bear heavy burdens and pressures. Milk powder is too thick, or mixed with fresh milk, the concentration of nutrients increases, exceeding the digestion and absorption limit of infant gastrointestinal tract. Not only can it not be digested, but it may also damage the digestive organs. Therefore, if you feed your baby with milk, you should decide how much water to add according to the quality of the milk and the age of the child.

Second, the more sugar the better.

It is the common sense of many parents that unsweetened milk is not easy to digest. Sugar is added to increase the calories supplied by carbohydrates, but it must be quantified. Generally, 5 ~ 8 grams of sugar is added per 100 ml of milk. If too much sugar is added, it will do harm to the growth and development of babies. Too much sugar enters the baby's body, which will retain water in the body, making the muscles and subcutaneous tissues soft and weak. This kind of baby looks fat, but its body resistance is very poor, which is called "mud paste type" in medicine. Too much sugar stored in the body will also become a risk factor for some diseases, such as dental caries, myopia and arteriosclerosis.

What sugar should I add to the milk? Sucrose is preferred. Sucrose enters the digestive tract, is decomposed by digestive juice, becomes glucose, and is absorbed by the human body. Some parents buy glucose for their children, which is unnecessary. Glucose is low in sweetness, and it is easy to exceed the prescribed range when used too much, and children will refuse to eat it because it is not sweet.

There is also a question of when to add sugar. Some parents heat sugar and milk together, so that lysine in milk will react with sugar at high temperature (80℃ ~ 100℃) to generate harmful substance glycosyl lysine. This substance will not only be absorbed by the human body, but also be harmful to the body, especially to children. Therefore, boiled milk should be dried to a warm temperature (40℃ ~ 50℃) before sugar is dissolved in milk.

Third, milk and chocolate.

Some parents think that since milk is a high-protein food and chocolate is an energy food, it must be beneficial to eat both at the same time. That was not the case. Adding chocolate to liquid milk will make calcium in milk react with oxalic acid in chocolate to produce "calcium oxalate". In this way, the originally nutritious calcium has become a substance harmful to human body, leading to calcium deficiency, diarrhea, delayed development of children, dry hair, easy fracture and increased incidence of urinary calculi.

Fourth, milk medicine kills two birds with one stone

Some people think that it is definitely good to take medicine with nutritious things, but this is extremely wrong. Milk can obviously affect the absorption rate of drugs in human body, so that the concentration of drugs in blood is significantly lower than that of non-milk users at the same time. Taking medicine with milk is also easy to make the medicine show a covering film, so that mineral ions such as calcium and magnesium in milk react with the medicine to generate water-insoluble substances, which not only reduces the curative effect, but also may cause harm to the body. Therefore, it is best not to drink milk 1 ~ 2 hours before and after taking the medicine.

Fifth, feed the baby with yogurt.

Yogurt is a healthy drink to help digestion. Some parents often feed their babies yogurt. Antibiotics produced by lactic acid bacteria in yogurt can inhibit the growth of many pathogenic bacteria, but it also destroys the growth conditions of normal flora beneficial to human body and affects the normal digestive function, especially for infants and premature infants with gastroenteritis. If you feed them yogurt, they may cause vomiting and gangrenous enteritis.

6. Add orange juice or lemon juice to milk to add flavor.

In order to make children like milk, it seems a good idea to add some orange juice or lemon juice to milk. But in fact, orange juice and lemon are fruits with high fruit acid. When fruit acid meets protein in milk, protein will be denatured, thus reducing the nutritional value of protein.

Seven, add rice soup and porridge to the milk.

Some parents think that this can make the nutrition complementary. In fact, this practice is very unscientific. Milk contains vitamin A, while rice soup and porridge are mainly starch, which contains lipoxygenase, which will destroy vitamin A. Children, especially infants, will be stunted and sickly if they do not take enough vitamin A. Therefore, even if you supplement nutrition, you should eat the two separately.

Eight, milk must be boiled.

Usually, milk disinfection does not require high temperature, 70℃ for 3 minutes and 60℃ for 6 minutes. If boiled and the temperature reaches 100℃, the lactose in milk will be coked and caramel will induce cancer. Secondly, after boiling, calcium in milk will precipitate with phosphoric acid, thus reducing the nutritional value of milk.

Nine, bottled milk placed in the sun can increase vitamin D.

Some parents learned from advertisements that vitamin D is needed for calcium supplementation, and more sunshine is a good way to get vitamin D, so they put bottled milk in the sun according to the prescription. In fact, this is not worth the loss. Milk may get some vitamin D, but it will lose vitamin B 1, vitamin B2 and vitamin C. Because these three nutrients will be decomposed in the sun, so that some or all of them will be lost. Moreover, lactose will ferment in the sun, which will make milk go bad.

Ten, condensed milk instead of milk.

Condensed milk is a kind of dairy products, which is made by evaporating fresh milk to 2/5 of its original capacity and then adding 40% sucrose to cans. Some people are influenced by "concentrated essence" and give their children condensed milk instead of milk. This is obviously wrong. Condensed milk is too sweet and must be diluted with 5 ~ 8 times of water. But when the sweetness meets the requirements, the concentration of protein and fat is often reduced by half compared with fresh milk. Infants and young children, if fed, will certainly not gain weight, look pale and get sick easily. If water is added to condensed milk to make the concentration of protein and fat close to that of fresh milk, the sugar content will be high. Feeding such "milk" to children is also easy to cause diarrhea in children. In addition, if children are used to sweetness, it will bring difficulties to add complementary food in the future.
