Milk is indeed a kind of food rich in nutrients such as protein and fat, which is of great help to children's growth and development. However, many parents let their children drink milk on an empty stomach in the morning, and some children go to school only with milk, which does not meet the nutritional requirements and is unscientific. Water accounts for a large proportion in milk. A bottle of milk is 230ml, water accounts for 87%, solid matter accounts for 13%, including protein, sugar, fat, minerals and vitamins, and the total calorie output is 666.5kJ Generally speaking, breakfast should account for 20 ~ 30% of the total calories in a day. Four-year-old children need 7560 kilojoules a day, and breakfast should get 15 12 ~ 2258 kilojoules, while a bottle of milk can only provide one-third of the calories; Furthermore, a 4-year-old child needs 60 grams of protein every day, and breakfast should provide at least 15 ~ 20 grams, while a bottle of milk only provides 8.05 grams. Therefore, drinking only one bottle of milk for breakfast does not meet the nutritional needs of children.

Because water accounts for a large proportion in milk, drinking more milk on an empty stomach dilutes gastric juice, which is not conducive to the digestion and absorption of food. In addition, on an empty stomach, intestinal peristalsis is fast, milk passes through the gastrointestinal tract quickly, and the retention time is short. Its nutrition is often too late to be absorbed, so it rushes into the large intestine and goes through the motions. Therefore, drinking milk on an empty stomach is not in line with nutrition and hygiene.

The ideal breakfast should be a high-protein and high-calorie meal, and its amount should not be less than a quarter of the whole day's food intake. If you want to drink a bottle of milk for breakfast, you can eat 50 grams of rice or pasta first, then add an egg and a little pickles and dried tofu, and then drink milk, so that milk can be mixed with other foods in the stomach, and the stay time in the stomach can be prolonged, which is beneficial to the digestion and absorption of nutrients. This is very good for children's health. Although the value and nutrition of milk are relatively high, it is best not to drink milk on an empty stomach early in the morning to avoid harm to the body.
