Some people will have some discomfort after drinking milk. Here are two conditions, milk allergy and lactose intolerance. I: Milk allergy 1. Concept: Milk allergy means that the body has an allergic reaction to milk (mainly certain proteins in milk such as α-S1 casein and β-lactoglobulin). It can also be called milk protein intolerance. Under normal circumstances, these proteins can be digested, however, if the body’s digestive capacity is insufficient, these two proteins may enter the body in undigested form, thus causing an allergic reaction. 2, the main occurrence of the population: newborn infants and young children and the elderly are prone to the onset of the population. Older people are not easy to digest large long-chain proteins because of their reduced digestive capacity. Newborn infants and young children have not yet completed the development of their digestive system and immune system. Generally speaking, newborn infants and toddlers are most sensitive from 0-6 months. After two years of age, with improved digestion and enhanced immune function, most children are no longer allergic to milk. 3. Main symptoms: first occurs in the skin, then in the gastrointestinal tract, respiratory tract, symptoms include abdominal pain, bloating, diarrhea, rash, vomiting, in severe cases asthma, blood in stool, etc. 2: Lactose intolerance 1. Concept: The only enzyme in the human body that can break down lactose is lactase. Due to the lack of lactase, lactose cannot be broken down in glucose and galactose to be absorbed into the blood, which is called “lactose indigestion” or “lactose malabsorption”. Due to the lack of lactase, lactose that is not broken down and absorbed enters the colon and is fermented by bacteria to produce fructic acid and gas, causing symptoms such as intestinal rumbling, abdominal pain, exhaustion and diarrhea, which is called
“lactose intolerance”. 2, the main occurrence of the population: mainly occurs in the following groups of people: normal adults, which is the most common and the main lactose intolerant group. This is followed by very rare congenital diseases, low intestinal lactase activity in infants due to premature birth, and damage to the intestinal mucosa due to intestinal surgery or other reasons, which can cause lactase activity to disappear temporarily for a month or longer, etc. Lactose intolerance in infants and children is relatively rare. < When a person is born, the lactase activity in the intestine is the highest, which can effectively guarantee the digestion and absorption of lactose in milk, thus providing effective energy and nutrition to the individual. As a person grows and develops, the lactase activity in the body decays in a regular manner, resulting in impaired lactose absorption. The phenomenon of "lactose intolerance" 3. The main symptoms of lactose intolerance: mainly manifested as some gastrointestinal symptoms, with abdominal tension, pain and diarrhea. 4, lactose intolerant patients can use some methods: do not drink milk on an empty stomach, do not drink too much milk at a time, or with cereals to eat together, or add cereal to eat together can reduce the symptoms of intolerance, Note: When consumers drink milk after some reactions, such as diarrhea and so on, there may be some reasons caused by their own body, rather than the cause of milk powder.
