In fact, the temperature of milk does affect its nutritional value, but it is high temperature rather than low temperature that will make milk lose its nutrition! Repeated or continuous heating of milk will combine phosphoric acid with calcium to form insoluble matter, which will lead to the decrease of calcium content in milk.
However, there is no problem of nutrient loss in iced milk. Just pay attention when drinking, if the child's stomach is weak, it is more likely to cause diarrhea after drinking. In addition, frozen milk is more likely to cause lactose intolerance because of its high lactose content.
In addition to drinking more milk, heredity, work and rest, and diet are the most important keys for children to grow taller! At the same time, let them have less contact with garbage, fried food and sugary drinks. What do you need to pay special attention to if you want to make your child superior by drinking milk?
Milk is called "white blood" by many nutritionists, and it is not difficult to see the value of milk from this name alone. Parents also like to give their children milk to supplement calcium, DHA and protein ... Then the problem comes!
■ How old can a child drink milk?
■ How much is better to drink every day?
■ Is there any preservative for milk that does not need refrigeration?
■ I heard that you can't drink milk on an empty stomach?
Recommended reading: 80% of children have insufficient intake of dairy products. Grasping breakfast and drinking milk are four ways to supplement calcium and promote development.
In today's article, let's take a good look at these problems!
1. How old can a child drink milk?
Suggested age: 1 years later. Why do you say that? The reason is actually very simple: drinking milk too early may have a negative impact on children's health.
1. The nutritional composition and proportion are not suitable for children under 1 year.
The contents of iron, linoleic acid and vitamin E in fresh milk are low, but the contents of sodium, potassium, chlorine and protein are too high. For children under 1 year old, replacing breast milk or formula milk with fresh milk will easily lead to nutritional imbalance.
2. allergic
/kloc-the gastrointestinal function of children under 0/year old is not yet mature, and drinking fresh milk can easily lead to allergies and even symptoms such as gastrointestinal bleeding.
3. Increase the burden on the kidneys
High concentrations of protein, sodium, potassium and chloride in fresh milk may increase the burden on children's kidneys and easily lead to dehydration. Therefore, the American Academy of Pediatrics advises children to add milk as much as possible after 1 year old.
Second, the milk that children drink is different from the milk that adults drink.
What's the difference between milk that children drink and milk that adults drink? The most important thing is: the fat content in milk! For children, fat is more important than we think: on the one hand, fat can provide energy for the rapid growth of children's bodies; On the other hand, fat can also provide essential fatty acids for the rapid development of children's brains.
Therefore, the American Academy of Pediatrics (AAP) also recommends:
1? 2-year-old children can drink whole milk. If the child is overweight or has a family history of obesity, high blood pressure or heart disease, the pediatrician may recommend low-fat milk (2% fat content). But note that children should not drink low-fat milk or skim milk with a fat content of only 1% before they are 2 years old.
At the same time, the World Health Organization (WHO) also recommended:
Skim milk is not recommended as the main food for children under 2 years old. Because skim milk does not contain essential fatty acids and lacks fat-soluble vitamins, the kidney load is high.
To sum up:
1. The choice of milk or other dairy products, except for special circumstances, all choose full-fat milk.
2. Children should not drink low-fat milk or skim milk with a fat content of only 1% before the age of 2.
3. How much milk should I drink every day?
This question is actually very simple to sum up:
■ 13? A 24-month-old baby needs to consume about 500 ml of milk every day. ■2? 6-year-old children, it is recommended to drink 300 milk a day? 400 ml. ■ For children over 6 years old, it is recommended to drink about 300ml of milk every day.
Note that the "milk quantity" mentioned here includes breast milk, milk, formula milk, cheese, yogurt and so on. If children don't like to drink milk, but the intake of cheese and yogurt is almost up to this standard, don't force them to drink so much!
In addition, parents need to pay attention to how much food to eat and how much milk to drink. This question is very personalized. Every baby is different, and every meal every day can't be exactly the same. As long as the baby's overall growth curve is normal, don't worry too much about drinking less milk and less non-staple food one day. After all, even adults sometimes have a bad appetite!
Fourth, rumors and truth about drinking milk.
1. You can't drink milk on an empty stomach.
Many "health masters" say that drinking milk on an empty stomach is easy to get cancer, especially for children. Cancer is really exaggerated, but whether you can drink milk on an empty stomach is really a score:
■ It is not recommended for children with lactose intolerance to drink on an empty stomach, otherwise it may cause problems such as diarrhea.
■ Children with normal lactose digestion ability can drink it at any time.
2. Drinking in the morning is different from drinking at night.
Some parents asked: I heard that drinking milk in the morning is easier to absorb nutrition, and children who drink milk at night will sleep well. Is it true?/You don't say.
Nothing! As long as children like it, they can drink it at any time. There is no difference in nutrition. But some children may have formed a habit, and drinking milk before going to bed is a necessary "ceremony", of course, no problem!
3. Normal temperature milk has preservatives, not as good as pasteurized milk?
The difference between pasteurized milk and normal temperature milk lies in the sterilization method:
■ Pasteurization (HTST ), 72 degrees Celsius, 15 seconds; This method will not completely kill all bacteria, and bacteria may rejuvenate in future preservation. Therefore, pasteurized milk must be refrigerated and cannot be preserved for too long.
■ 135℃ UHT1and 2 seconds; Ultra-high temperature can kill almost all bacteria, so it can be stored for a long time at room temperature under sealed conditions. Therefore, normal temperature milk does not need preservatives to prolong its storage time, and it relies on sterilization and sealing.
At the same time, there is not much difference in protein, fat, carbohydrate and calcium content between domestic and imported pasteurized milk and domestic and imported normal temperature milk.

5. How to choose good milk for children?
In the final analysis: look at the nutrient composition table.
Look at the nutrient composition table
The shorter the nutrient list, the less additives. Children's pure milk, only "raw milk" is the best in the nutrient composition table. In the nutrient composition table, the most important contents are protein, fat and carbohydrate.
■ protein content: the national minimum standard for protein content of milk: pure milk with protein content ≥ 2.9g/100ml, denatured milk with content ≥ 2.3g/100ml and protein content ≤ 2.3g/100ml are drinks.
■ Fat content: 1? 2-year-old baby has a high demand for fat, so it is recommended to choose whole milk; Babies over 2 years old can be full-fat or low-fat milk if there is no obesity problem.
■ Carbohydrate content: The carbohydrate in milk is mainly lactose. Generally speaking, the higher the lactose content, the sweeter the taste, and the content is about 5g.
