Milk is an indispensable food in people's lives. It is of good quality and low price, easy to eat, but if you "just boil it and drink", you will make some "taken for granted" mistakes, which will greatly reduce the nutritional value of milk.
The more sugar, the better. Many parents "consensus" is that milk without sugar is not easy to digest. Adding sugar is to increase the heat supplied by carbohydrates, but must be quantitative, generally 5-8 grams of sugar per 100 ml of milk. If too much sugar is added, it will be detrimental to the growth and development of infants. Excessive sugar entering the infant's body will retain water in the body, making muscles and subcutaneous tissue become soft and powerless. Such babies look fat, but their physical resistance is very poor. In medicine, this is called the "mud paste type" figure. Excessive sugar stored in the body will also become a risk factor for some diseases, such as tooth decay, arteriosclerosis, etc.
What kind of sugar should be added to milk? The best is sucrose. Sucrose enters the digestive tract and is decomposed by digestive fluid, then absorbed by the human body as glucose. Some parents specifically buy glucose for their children, which is unnecessary. Glucose has low sweetness, using too much is easy to exceed the specified range, and children will refuse to eat because it is not sweet enough.
There is also the issue of when to add sugar. Some parents heat the sugar with milk together, so that lysine in milk will react with sugar at high temperature (80℃～100℃), generating harmful substance glycolysine. This substance cannot be absorbed by the human body, but also harms health, especially for children. Therefore, first cool down the boiled milk to warm (40℃～50℃), then dissolve the sugar in the milk.
The thicker the milk, the better. Some parents think that the thicker the milk, the more nutrition the child gets, which is unscientific.
So-called concentrated milk refers to adding more milk powder and less water to milk, making the concentration of milk exceed the normal ratio standard. There are also parents who are afraid that fresh milk is too light, so they add milk powder to it. In fact, the concentration of milk that infants drink should be proportional to the age of the child, and its concentration should gradually increase according to the month. Even for newborns within one month, the proportion of water added to milk should be gradually reduced according to the digestion situation. If infants often eat concentrated milk, it will cause diarrhea, constipation, loss of appetite, or even refusal to eat. In the long run, weight will not only fail to increase, but acute hemorrhagic enteritis may occur. This is because the organs of infants are delicate and can't bear heavy burden and pressure. Over-concentrated milk powder or adding milk powder to fresh milk increases the concentration of nutrients, exceeding the limit of gastrointestinal digestion and absorption in infants, not only can't be digested, but also may damage the digestive organs. Therefore, if feeding infants with milk, the amount of water added should be determined according to the quality of milk and the age of the child.
Take medicine with milk to achieve two goals at once. Some people think that taking medicine with nutritious things must be beneficial, which is extremely wrong. Milk can significantly affect the speed of drug absorption in the human body, making the concentration of drugs in the blood obviously lower than those who do not take medicine with milk within the same time. Taking medicine with milk can easily form a covering film on the surface of the drug, causing calcium and magnesium minerals in milk to chemically react with the drug and generate non-water-soluble substances. This not only reduces the efficacy of the drug, but may also harm the body. Therefore, it is best not to drink milk within 1-2 hours before and after taking medicine.
Milk with chocolate. Some parents think that since milk is a high-protein food and chocolate is an energy food, eating them together must be very beneficial. This is not the case. Liquid milk plus chocolate will cause the calcium in milk to chemically react with the oxalic acid in chocolate, generating "calcium oxalate". Thus, calcium that originally has nutritional value becomes a harmful substance to the human body, leading to calcium deficiency, diarrhea, delayed development in adolescents, dry hair, easy fractures and increased incidence of urinary calculi.
Feeding infants with yogurt. Yogurt is a healthy drink that helps digestion, and some parents often feed infants with yogurt. However, the antibiotics produced by lactic acid bacteria in yogurt not only inhibit the growth of many pathogenic bacteria, but also destroy the growth conditions of normal flora beneficial to the human body, and affect normal digestive function. Especially for infants suffering from gastroenteritis and premature infants, feeding them with yogurt may cause vomiting and gangrenous enteritis.
Adding orange juice or lemon juice to milk to enhance flavor. To make children love drinking milk, adding a little orange juice or lemon juice to milk seems like a good idea. In fact, orange juice and lemon belong to high fruit acid fruits, and fruit acid encounters protein in milk, making the protein denatured, thus reducing the nutritional value of protein.
Replacing milk with condensed milk. Condensed milk is a milk product made by evaporating fresh milk to 2/5 of its original volume, then adding 40% sucrose and canned. Someone influenced by "all condensation is essence" replaces milk with condensed milk for children to drink. This is obviously wrong. Condensed milk is too sweet, and must be diluted with 5-8 times water. But when the sweetness meets the requirement, the concentration of protein and fat is often halved compared with fresh milk, which certainly can't meet the needs of growth and development of infants, and will cause their weight not to increase, pale complexion, prone to illness, etc. If water is added to condensed milk, making the concentration of protein and fat close to fresh milk, then the sugar content will be too high, feeding children with such "milk" is likely to cause infantile diarrhea. In addition, if children get used to overly sweet taste, it will bring difficulties to later complementary food.
Adding rice soup or porridge to milk. Some parents think that doing this can make nutrients complement each other. In fact, this practice is very unscientific. Milk contains vitamin A, while rice soup and porridge mainly contain starch. They contain lipoxidase, which will destroy vitamin A. Children, especially infants, if they lack vitamin A intake, will cause slow development and weak constitution in infants. Therefore, even if it is for the purpose of supplementing nutrition, the two should be eaten separately.
Milk must be boiled. Usually, the temperature required for milk disinfection is not high, 3 minutes at 70℃, 6 minutes at 60℃ is enough. If boiled, the temperature reaches 100℃, the lactose in milk will undergo caramelization, and caramel can induce cancer. Secondly, after boiling, calcium in milk will appear phosphate precipitation phenomenon, thus reducing the nutritional value of milk.
Put bottled milk in the sun to increase vitamin D. Some parents learn from advertisements: calcium supplementation also requires vitamin D supplementation, and getting more sunshine is a good way to obtain vitamin D, so they put bottled milk under the sun. In fact, this is counterproductive. Milk may get some vitamin D, but it loses vitamin B1, vitamin B2 and vitamin C. Because these three nutrients decompose under sunlight, resulting in partial or total loss; and under sunlight, lactose will ferment, causing milk to spoil.
