Everyone knows that milk is calcium supplement, but there is a way to drink milk. If the method is not correct, calcium supplementation will be greatly reduced. In daily life, we need to pay attention to the following five conditions, which will lead to the absorption of calcium in milk.
1, drinking milk on an empty stomach is easy to diarrhea
The lactose in milk needs to be decomposed by lactase. After the lactose is decomposed, the monosaccharide can enter the blood through the small intestine wall and be absorbed by the human body.
If there is no lactase in the small intestine or its vitality is low, lactose can not be decomposed, and it enters the large intestine intact, and is metabolized, fermented, acid-producing, and gas-producing by bacteria such as Escherichia coli, and symptoms such as diarrhea appear.
According to statistics, there are 2 or more adults in China who lack lactase. That is to say, in China, 66% to 97% (different diagnostic criteria have different results), as long as you drink milk on an empty stomach, or drink milk in large quantities at a time, it will cause abdominal distension and diarrhea.Drinking milk on an empty stomach reduces absorption rate
- Drinking milk on an empty stomach reduces absorption rate
After drinking milk on an empty stomach, the passage of milk in the gastrointestinal tract is accelerated, the residence time in the stomach becomes shorter, and the emptying time becomes faster, resulting in a decrease in absorption efficiency.
Therefore, drink milk with solid food, preferably with staple foods such as bread, cakes, snacks, biscuits, etc.
Drink with tea and coffee
Milk is rich in calcium ions. Tea contains tannic acid. Calcium reacts with tannic acid to produce insoluble calcium salts, which affects the absorption of calcium. The caffeine in coffee is a strong decalcifying agent.
According to statistics, the probability of osteoporosis is relatively high in people who drink tea or drink coffee for a long time or a long period of time. This situation is mainly related to the absorption of calcium by drinking tea or coffee.
3, treatment of milk with high temperature or low temperature
Mothers care for their babies from time to time, or are afraid that milk is unsanitary, or because of the traditional concept, many people like to use freshly cooked hot water to wash milk powder. In fact, this method is not scientific. Because from a nutritional point of view, high temperature will denature casein and whey protein in milk; from a hygienic point of view, even if it is washed with boiling water of 100 °C, it will not achieve disinfection.
Milk should not be cooked for a long time because the protein in milk is affected by high temperature, and it will change from sol state to gel state, causing sediment to appear and the nutritional value is reduced. If you consider disinfection and boil milk, you don’t have to, because the fresh milk produced by regular manufacturers is sterilized.
Milk should not be stored frozen, because freezing will denature proteins in milk, fat stratification, and after thawing, protein and fat precipitate and solidify, which is not conducive to the absorption of the human body, so that the value of milk is greatly reduced.

4, with milk to take drugs
Some medication instructions may indicate that milk does not affect the absorption of the drug. However, it is best to use clear water for the medication, and there is absolutely no need to take it with milk.
Because the two may destroy each other and affect each other. The protein contained in milk is combined with a variety of metal ions, which affects some metal ion-containing drugs to exert normal effects in the human body
5, taking milk and calcium tablets together
Some people may think that calcium tablets are calcium supplements, and milk is also calcium supplementation. Is it twice as much as drinking calcium?
In fact, if the amount of calcium is too high, the absorption rate will decrease, resulting in an effect of 1+1<2. The calcium tablets and milk are placed in different meals and the absorption rate will be higher.
