Milk whitening misunderstanding to avoid, winter how to use milk whitening effect? In daily life, most people have misunderstandings about milk nutrition, which will lead to the loss of nutrition that should be absorbed. Therefore, misunderstandings about milk whitening should be avoided, and we will teach you how to use milk whitening!
The thicker the milk, the better
Some people think that the thicker the milk, the more nutrition the body gets. This is unscientific.
The so-called concentrated milk refers to adding more milk powder and less water in the milk, so that the concentration of milk exceeds the normal proportion standard. Some people fear that the fresh milk is too light, so they add milk powder to it. If infants often eat too much milk, it will cause diarrhea, constipation, loss of appetite, and even refusal to eat, it will also cause acute hemorrhagic enteritis. This is because the organs of infants are delicate and can not bear the heavy burden and pressure.
Add orange or lemon juice to milk to add flavor
It seems a good way to add orange juice or lemon juice to milk, but in fact, both orange juice and lemon belong to high fructic acid fruits. When the fruit acid meets the protein in milk, it will denaturate the protein, thus reducing the nutritional value of protein.
Milk and chocolate
Some people think that since milk is a high protein food and chocolate is an energy food, it will be beneficial to eat both at the same time. This is not the case. Liquid milk and chocolate will make the calcium in milk and oxalic acid in chocolate produce chemical reaction to produce 'calcium oxalate'. Therefore, calcium, which has been nutritious, has become a harmful substance to human body, resulting in calcium deficiency, diarrhea, delayed development of children, dry hair, easy fracture and increased incidence rate of urinary calculi.
The more sugar, the better
Unsweetened milk is difficult to digest, which is the consensus of many people. Sugar is to increase the calories supplied by carbohydrates, but must be quantitative, generally 5-8 grams of sugar per 100 ml of milk.
What kind of sugar is good in the milk? The best is sugar. Sucrose enters the digestive tract and is decomposed by the digestive juice, which turns into glucose and is absorbed by the human body. The sweetness of glucose is low, and it is easy to exceed the specified range after using too much glucose.
There is also the question of when to add sugar. When the sugar and milk are heated together, the lysine in the milk will react with the sugar at high temperature (80 ℃ - 100 ℃) to form the harmful sugar lysine. This substance is not only not absorbed by human body, but also harmful to health. Therefore, the boiled milk should be dried to a warm temperature (40 ℃ - 50 ℃), and then the sugar should be dissolved in the milk.
Milk kills two birds with one stone
Some people think that it is definitely beneficial to take medicine with nutritious things. In fact, this is extremely wrong. Milk can significantly 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 drug users in the same time. Taking medicine with milk is also easy to make the drug show the formation of a covering film, so that the calcium and magnesium and other mineral ions in milk react with the drug to produce water-insoluble substances, which not only reduces the efficacy, but also may cause harm to the body. Therefore, it is best not to drink milk within 1-2 hours before and after taking the medicine.
The milk must be boiled
Usually, the temperature requirement of milk disinfection is not high. It takes 3 minutes at 70 ℃ and 6 minutes at 60 ℃. If boiled, the temperature reaches 100 ℃, lactose in milk will appear coking phenomenon, and caramel can induce cancer. Secondly, after boiling, calcium in milk will appear phosphate precipitation phenomenon, thus reducing the nutritional value of milk.
Add rice soup and porridge to the milk
Some people think that this can make nutrition complementary. In fact, this is not scientific. Milk contains vitamin A, while rice soup and porridge are mainly starch. They contain lipoxygenase, which can destroy vitamin A. Children, especially infants and young children, if the intake of vitamin A is insufficient, it will make infants and young children grow slowly, weak and sick. Therefore, even if it is to supplement nutrition, the two should be eaten separately.
