Everyone knows that milk supplements calcium, but there is a way to drink milk. If it is not correct way, calcium supplementation will be greatly reduced. The following 5 taboos need to be understood in detail.
Drink milk on an empty stomach is prone to diarrhea. Lactose in milk needs lactase to decompose. After lactose is decomposed, monosaccharides in the milk can enter the blood through the wall of the small intestine and be absorbed by the body.
If there is no lactase in the small intestine or its activity is low, lactose can not be decomposed, but it can enter the large intestine intact and be metabolized, fermented, acid- producing and gas produced by Escherichia coli and other bacteria.So there are diarrhea and other symptoms of discomfort.
Drinking milk on an empty stomach reduces the rate of absorption. After drinking milk on an empty stomach, the passing time of milk in the gastrointestinal tract is accelerated, the residence time in the stomach is shortened, and the emptying time becomes faster, leading to a decrease in absorption efficiency. Therefore, when you drink milk, you should use solid foods, preferably with staple foods such as bread, cakes, snacks, and cookies.
Milk is rich in calcium ions. Tea contains tannic acid. Calcium reacts with tannic acid to produce insoluble calcium salts that can affect the absorption of calcium. Caffeine in coffee is a strong decalcifying agent. People who drink a lot of tea or coffee for a long time have a higher probability of osteoporosis.
Many people like to use fresh hot boiling water to flush milk powder. In fact, this method is not scientific. This is because high temperature can make milk casein, whey protein denaturation. In fact, it is most suitable to flush milk powder with warm water at 60-70°C.
Milk should not be boiled at high temperatures for a long time, because the protein in milk is affected by high temperature, and it will change from a sol state to a gel state, resulting in the appearance of sediments and reduced nutritional value. Milk should not be stored frozen, because freezing will denature protein in milk, fat stratification, and after thawing, protein and fat precipitation, solidification, is not conducive to the body's absorption, so that the value of milk is greatly reduced.
The instructions for some medicines may indicate that milk does not affect the absorption of the medicine. But in any case, it is best to take the medicine with clear water. There is no need to take it with milk at all. Because they may be mutually destructive and affect each other. The protein contained in milk is combined with various metal ions, which will affect some drugs containing metal ions to exert normal efficacy in the human body.
Some people may think that calcium tablets are calcium supplements, and milk is calcium supplements. Is the effect of drinking calcium supplements doubled? In fact, the high calcium content will lead to a decrease in the absorption rate, resulting in an effect of 1+1<2. Divide the calcium and milk in different meals and the absorption rate will be higher.
