Eight misunderstandings of netizens drinking milk

Milk is an essential nutrient for many people in daily life. However, ordinary people still have many misunderstandings about the nutrition of milk, causing the loss of nutrients that should have been absorbed, thus causing harm to the body.

1) Milk is not as thick as possible

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. If infants and young children often eat thick milk, it will cause diarrhea, constipation, loss of appetite, or even refuse to eat, but also cause acute hemorrhagic enteritis. Because the organs of infants and young children are delicate, they cannot afford to bear too much burden and pressure.

2) More sugar is not better

Milk adds sugar to increase the calories provided by carbohydrates, but it must be quantified, typically adding 5 to 8 grams of sugar per 100 ml of milk.

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 easily absorbed by the body. The glucose sweetness is low, and it is easy to use more than the specified range.

When to add sugar? When sugar is heated with milk, lysine in milk reacts with sugar at high temperatures to produce the harmful substance glycosyl-lysine. Therefore, the boiled milk should first be allowed to warm up and sugar added.

3) Milk is not good with chocolate

Some people think that since milk is a high-protein food, chocolate is also an energy food, and both of them will have great benefits 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.

4) Milk medication may harm the body

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 of drugs, so that the concentration of drugs in the blood is significantly lower than the non-milk medication in the same time. It is also easy to form a coating on the surface of the drug by using milk, so that calcium and magnesium minerals in the milk chemically react with the drug to form 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 to 2 hours before and after taking the medicine.

5) Milk and orange juice reduce nutritional value

Adding some orange juice or lemon juice to milk looks like a good idea, but in fact, both orange juice and lemon are high fruit acid fruits, and the acid meets the protein in the milk and denatures the protein, which reduces the protein. The nutritional value.

6) Milk must not be mixed with rice soup and porridge

Adding rice soup and porridge to milk is unscientific. 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.

7) Milk does not have to boil

Usually, the temperature requirement for milk disinfection is not high. It takes 3 minutes at 70 degrees Celsius and 6 minutes at 60 degrees Celsius. If it is boiled, ie, the temperature reaches 100 degrees Celsius, the lactose in the milk will appear to be charred, and caramel can induce cancer. Second, calcium in milk after boiled will cause phosphoric acid precipitation, which reduces the nutritional value of milk.

8) Do not put milk in the sun

Some people have learned from advertisements that calcium supplements are supplemented with vitamin D. Many sun exposures are a good way to take vitamin D, so they put the bottled milk in the sun and dry it. In fact, doing so is not worth the candle. Milk may therefore receive some vitamin D, but it will also lose 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.
