Milk is widely recognized as a "nearly perfect" source of nutrition. However, some consumers suffer from "no happiness", as soon as they drink milk, they will feel bloated, and even have abdominal pain and diarrhea. What's going on here? On October 30th, the Market Supervision Bureau of Jiangxi Province issued a consumption reminder specifically on this matter. Milk is very important and can be considered a necessity. Milk can be considered a "full price food" for humans, and its nutrients can be almost completely digested and absorbed by the human body. Milk is rich in fat, protein, lactose, 20 amino acids required by the human body, and is rich in minerals such as calcium, phosphorus, potassium, sodium, iron, etc. Moreover, calcium in milk is more easily absorbed by the human body. Milk has an appropriate ratio of calcium and phosphorus, making it an ideal nutritional food for promoting the development of bones and teeth in children and adolescents. The 2022 Dietary Guidelines for Chinese Residents recommend consuming 300-500ml of liquid milk every day, and it is recommended to consider milk products as a necessary dietary component. How to judge lactose intolerance? Why do some people feel bloating, stomach growling, and even symptoms such as abdominal pain and diarrhea within 0.5-2 hours after drinking milk. The more milk you consume, the more obvious the symptoms. Experts explain that this is likely caused by the body's intolerance to lactose. Lactose intolerance is caused by a lack of lactase in the small intestine, which prevents the complete breakdown and absorption of lactose in milk, leading to its entry into the colon. It is broken down by intestinal bacteria, producing a large amount of fatty acids, hydrogen gas, and carbon dioxide, stimulating the intestinal wall, causing an increase in intestinal osmotic pressure, increasing water content in the intestinal cavity, and increasing intestinal peristalsis, leading to symptoms such as abdominal ringing, intestinal ringing, abdominal pain, and diarrhea. Can people who are lactose intolerant completely avoid drinking milk? There are significant individual differences in their tolerance to milk. Healthy adults who are lactose intolerant can also choose suitable dairy products and drink milk in moderation based on their own situation. Common methods include drinking milk in small amounts multiple times, which helps induce the ability of the intestine to decompose and digest lactose, gradually allowing the intestine to accept lactose from milk and improving its tolerance to lactose. Choose fermented dairy products such as yogurt and cheese. Some lactose in yogurt has been converted into lactic acid by lactic acid bacteria, so lactose intolerants have a higher tolerance to yogurt than milk. Choose to drink soothing milk. The lactose in Shuhua milk has been broken down by the added lactase to produce glucose and galactose, so Shuhua milk is more suitable for people with lactose intolerance to drink. Milk containing beverages are not equal to milk. The Jiangxi Provincial Market Supervision Bureau reminds consumers that milk containing beverages are not equal to milk, and consumers must not be deceived by the word "milk" in milk containing beverages. Because milk containing beverages are actually a type of beverage, their nutritional value is completely different from that of milk. Consumers can distinguish by looking at the labels, ingredient lists, and nutritional ingredient lists for protein and raw milk content. At the same time, consumers also have differences in storage after purchasing dairy products. For example, pasteurized milk and "live bacterial" fermented milk have a shorter shelf life, usually 2-30 days. After purchase, they should be refrigerated and consumed within the shelf life. Fermented milk, sterilized milk and other products that have undergone heat treatment can be stored at room temperature, with a shelf life generally not exceeding six months. They should be consumed as soon as possible after being opened. In addition, patients with lactose intolerance should pay attention to the risk of calcium deficiency. If lactose intolerance occurs due to the absence of
