Is it suitable for drinking milk in hot weather?

As we all know, milk is a nutritious drink, which is a good tonic for the elderly, patients, pregnant women and children. However, many people think that the summer climate is hot, the body sweats a lot, and drinking milk is easy to get angry. Therefore, it is not suitable to drink milk in summer. In fact, there is no scientific reason for this statement. The summer climate is hot, and the human body sweats more. Milk contains about 78% water, and its protein and fat are easily digested and absorbed by human body. Therefore, drinking milk in summer can not only replenish the water lost by the body, but also increase the nutrients, which is extremely beneficial to maintaining good health. Modern scientific research also found that milk contains a variety of immunoglobulins, such as antibodies against Salmonella and poliovirus, which can greatly enhance human immunity and disease resistance. From this point of view, drinking milk in summer will not only "get angry", but also relieve viruses and resist viruses. Others think that milk in summer is not as nutritious as milk in winter. In fact, the quality of milk mainly depends on the quality of feed and the health of cattle, and has nothing to do with the season. It is worth noting that drinking milk in summer should pay special attention to hygiene to prevent drinking spoiled milk. Because of its high nutritional content, milk is easy to become a medium for bacterial reproduction in summer, so you should buy good quality sterilized milk instead of raw milk. Cook and drink now, and cook as much as you drink. The remaining milk should be kept in the freezer at low temperature, preferably at 4℃, and cannot be frozen in the freezer, otherwise its nutritional value will be destroyed. In addition, don't add water to fresh milk that you can't drink for the time being, otherwise it will go bad easily. In summer, people are very tired. High temperature leads to a lot of perspiration, which also leads to the loss of calcium in the body. The results of the third national nutrition survey conducted by the Institute of Nutrition and Food Hygiene of Chinese Academy of Preventive Medicine show that calcium is the most lacking nutrient for Chinese residents at present, and the per capita calcium intake is less than 50% of the supply. The objective phenomenon of calcium loss with sweat in summer makes calcium deficiency more serious! Drinking milk is the best way for people to supplement calcium, and drinking any beverage can't compare with it. Generally 100 ml milk contains calcium 104 mg. People who eat 400-500 ml of milk every day can effectively supplement calcium deficiency in the body. Milk is a friend of people's mobility. However, in order to make it really useful to you, you must stay away from the following five ways of drinking milk: 1. Boiling for drinking: Boiling will denature protein in milk, make the particles bigger, and hinder digestion and absorption. In fact, bagged milk has undergone strict purification and disinfection to ensure safety. Just put the bag in hot water for 5- 10 minutes and you can drink it. 2. Drink milk on an empty stomach in the morning: In the morning, on an empty stomach, the nutrients in milk are excreted into the large intestine due to the rapid peristalsis of the intestine. 3. Drink iced milk: In hot summer, people think that drinking iced milk can strengthen the body, cool off the heat and kill two birds with one stone. In fact, iced milk will increase intestinal peristalsis and cause mild diarrhea; It also leads to the recurrence of old diseases in patients with ulcers, cholecystitis and enteritis. 4. Store milk in thermos: If you store the milk you can't finish in thermos, bacteria will multiply in a large number in less than a few hours, which will make the milk go bad and inedible. 5. Drinking milk is the same as drinking acidic drinks, because acidic drinks will make protein in milk coagulate in the stomach and affect the absorption of nutrients. Therefore, when you want to drink juice and other drinks, you should take them every hour. In daily life, some people will have abdominal distension after drinking milk, and I don't know why. After a long time, they don't drink milk or even eat dairy products. Actually, it's not necessary Abdominal distension after drinking milk is because these people lack lactase in their small intestine. Lactose is a unique sugar in milk. It must be hydrolyzed by lactase in the small intestine before it can be absorbed. However, people with lactase deficiency, after eating milk, the lactose in milk can not be completely digested and absorbed and stays in the intestine. Under the action of bacteria, it will ferment, produce gas and have abdominal distension. As long as you drink no more than 150 ml of milk, you can generally avoid bloating. In addition, it is also a good way to switch to yogurt and cheese, because yogurt and cheese are fermented dairy products, and their lactose content has been significantly reduced.
