Milk is an indispensable food in people's lives. It is inexpensive and simple to eat, but if you “boil it and drink itâ€, you will make some “take it for granted†mistakes, which will greatly reduce the nutritional value of milk.
The more sugar the better
Unsweetened milk is not easy to digest, which is the "consensus" of many parents. Sugar is added to increase the calories provided by carbohydrates, but it must be quantified, typically adding 5-8 grams of sugar per 100 ml of milk. If you add too much sugar, there are disadvantages to the growth and development of infants and young children. Too much sugar enters the baby's body, leaving water in the body and weakening the muscles and subcutaneous tissue. Such infants look very fat, but the body's resistance is poor, medically known as "mud-type" body shape. Excess sugar is stored in the body and can also be a risk factor for some diseases, such as caries, myopia, and arteriosclerosis.
What is sugar in milk? The best is sucrose. After sucrose enters the digestive tract and is digested by digestive fluids, it becomes glucose that is absorbed by the body. Some parents specifically buy glucose for their children. This is not necessary. Glucose is low in sweetness, and it is easy to use more than the prescribed range, and the child will refuse to eat because it is not sweet.
There is also a question of when to add sugar. Some parents add sugar and milk together, so that lysine in milk reacts with sugar at high temperatures (80°C to 100°C) to produce the harmful substance glycosyl-lysine. This kind of material will not only not be absorbed by the body, but it will also endanger health, especially for children. Therefore, the boiled milk should be first dried to warm (40 °C ~ 50 °C), then sugar into the milk to dissolve.
The thicker the milk, the better
Some parents think that the more concentrated the milk, the more nutrition the child gets, which is unscientific.
The so-called over-concentrated milk refers to adding more milk and less water in the milk, so that the concentration of milk exceeds the normal ratio standard. Some parents fear that fresh milk is too light, and they add milk powder to them. In fact, the shade of milk consumed by infants and young children should be proportional to the age of the child, and its concentration should be gradually increased according to the age of the month. Even if the newborn is less than one month old, the proportion of milk mixed with water should be gradually reduced according to the digestion. If infants and young children often eat thick milk, can cause diarrhea, constipation, loss of appetite, or even refuse to eat, as time goes by, weight can not only increase, but also cause acute hemorrhagic enteritis. This is because the organs of infants and young children are delicate and cannot withstand the heavy burden and pressure. If milk powder is over-concentrated or if milk powder is incorporated into fresh milk, the concentration of nutrients in the milk increases, which exceeds the limits of gastrointestinal digestion and absorption of infants and young children. It can not only be digested, but it may also damage the digestive organs. Therefore, if milk is used to feed infants, the amount of water should be determined depending on the quality of the milk and the age of the child.
Milk takes two pills
Some people think that it would be good to use nutritious drugs to deliver drugs. In fact, this is extremely wrong. Milk can significantly affect the body's absorption rate of drugs, so that the concentration of drugs in the blood is significantly lower than non-milk medication in the same time. The use of milk to take medicine is also easy to show that the drug forms a cover film, so that calcium and magnesium and other mineral ions in the milk chemically react with the drug, resulting in non-water soluble substances, which not only reduces the efficacy, but also may cause harm to the body. Therefore, it is best not to drink milk within 1 to 2 hours before and after taking the medicine.
Milk and chocolate
Some parents think that since milk is a high-protein food, chocolate is also an energy food, and it is of great benefit for both to eat at the same time. But in fact, it's not. Liquid milk plus chocolate causes the calcium in the milk to react chemically with the oxalic acid in the chocolate, producing "calcium oxalate." As a result, calcium, which originally had nutritional value, has become a substance harmful to the human body, resulting in calcium deficiency, diarrhea, delayed development of young children, dry hair, easy fractures, and increased incidence of urinary tract stones.
Feeding baby with yogurt
Yogurt is a healthy drink that helps digestion, and some parents often use yogurt to feed babies. However, antibiotics produced by lactic acid bacteria in yoghurt, although they can inhibit the growth of many pathogenic bacteria, but also undermine the growth conditions of the normal flora that are beneficial to humans, but also affect the normal digestive function, especially the baby suffering from gastroenteritis Infants and premature infants who feed them on yoghurt may cause vomiting and gangrenous enteritis.
Add orange juice or lemon juice to add flavor to milk
In order to let the children love to drink milk, adding orange juice or lemon juice to the milk looks like a good idea. However, in fact, orange juice and lemon are both high fruit acid fruits, while fruit acids encounter proteins in milk, which will denature proteins, thereby reducing the nutritional value of proteins.
Condensed milk instead of milk
Condensed milk is a kind of milk product that is made by evaporating fresh milk to 2/5 of its original capacity, and then adding 40% of sucrose to canning. Some people are influenced by "everything that is concentrated is the essence" and they use condensed milk instead of milk to give their children a drink. It is obviously wrong to do so. Condensed milk is too sweet and must be diluted with 5-8 times of water. However, when the sweetness meets the requirements, the concentration of protein and fat is often reduced by half compared with that of fresh milk. If infants and young children are fed, of course, they cannot meet the needs of their growth and development, but they also cause them to lose weight, pale, and easy to get sick. If water is added to the condensed milk to make the concentration of protein and fat close to that of fresh milk, then the sugar content will be high. Using such "milk" to feed the child can also easily cause diarrhea in children. In addition, if children are accustomed to sweet taste, it will be difficult to add supplementary food later.
Add rice soup and porridge to milk
Some parents think that doing so can make nutrition complementary. Actually this method is not very scientific. Milk contains vitamin A, while rice soup and rice porridge mainly consist of starch. They contain lipoxygenase, which destroys vitamin A. Children, especially infants and young children, suffer from inadequate growth of vitamin A, which can cause infants and young children to develop stunted and sickly. Therefore, even if you want to supplement your nutrition, you should eat them separately.
Milk must be boiled
In general, the temperature requirement for milk disinfection is not high. It takes 3 minutes at 70°C and 6 minutes at 60°C. If boiled, the temperature reaches 100 °C, and the lactose in the milk will appear coking, and caramel can induce cancer. Second, calcium in milk after boiled will cause phosphoric acid precipitation, which reduces the nutritional value of milk.
Bottled milk dried in the sun can increase vitamin D
Some parents learn from advertisements that calcium supplements are supplemented with vitamin D. Many sun exposures are a good way to take vitamin D, and they then place the bottled milk in the sun and dry it. In fact, doing so is not worth the candle. Milk may get some vitamin D, but it loses vitamin B1, vitamin B2, and vitamin C. Because these three major nutrients break down in the sun, resulting in partial or total loss, and in the sun, lactose will glycosylate and degrade milk.
