Lactose intolerance

Many of you may not have heard of lactose intolerance in your life. But you should know about lactose. Lactose intolerance is caused by the fact that the lactose absorbed by our body is not fully broken down. Therefore, to prevent the occurrence of this disease, we need to improve the body's digestive ability, improve the degradation of lactose and its own absorption capacity.

If lactose is not fully broken down, it is likely to have a certain impact on our body, so we hope that when you eat foods rich in lactose, you should eat more digestible substances to help our stomach absorb.

When undigested and absorbed lactose enters the colon, it is fermented by intestinal bacteria into small molecular organic acids such as acetic acid, propionic acid, butyric acid, etc.

It also produces some gases such as methane, H2, CO2, etc. Most of these products can be reabsorbed by the colon. Lactase deficiency in the small intestinal mucosa of newborns is the main cause of the disease. It may also be caused in some people due to long-term lack of milk and dairy products.

2 Symptoms Edit this paragraph Unabsorbed or undecomposed lactose can cause intestinal rumbling, abdominal bloating, abdominal pain, flatulence, discomfort, diarrhea and other symptoms. Some people may also experience belching, nausea, etc. These symptoms are called lactose intolerance. Symptoms of lactose intolerance vary greatly from person to person. Severe lactose intolerance usually occurs within 30 minutes to several hours after consuming a certain amount of lactose.

Lactose intolerance has a greater impact on infants and young children, and is accompanied by diaper rash, vomiting, slowed growth and development, etc. Adults sometimes experience nausea. The number and severity of intolerance symptoms are related to many factors, such as lactase activity in the small intestine, the amount of lactose ingested, and whether other types of food are ingested at the same time.

3 Prevention Edit this section 1. Consume dairy products in small amounts and multiple times. Even individuals with lactase deficiency can tolerate small amounts of milk (120ml to 240ml) without experiencing intolerance symptoms. Limit the total amount of lactose consumed in a day. The general lactose limit is 12 grams. Eating small amounts frequently can also reduce lactose intolerance reactions. The amount consumed at one time should not exceed 250 ml. As long as you can grasp the reasonable interval time and total daily milk intake when drinking milk, you can avoid symptoms of lactose intolerance. Please note that infants and young children who are allergic to cow's milk should choose goat's milk or other dairy products.

2. It is not advisable to drink milk on an empty stomach. People with lactose intolerance should not drink milk on an empty stomach in the early morning. Drinking milk while eating other foods, such as dairy products with meat and fatty foods, can reduce or eliminate lactose intolerance symptoms.

3. Use fermented milk (especially yogurt) instead of fresh milk first. 20% to 30% of the lactose in fermented milk has been degraded, making it easy to digest and absorb. Eating yogurt can also improve lactose malabsorption and lactose intolerance, and it is also very convenient to eat.

4. Drink goat milk. The lactose content in goat milk is lower than that in cow milk, and it is rich in ATP (adenosine triphosphate), which can promote the decomposition and conversion of lactose. Therefore, it is not easy to develop "lactose intolerance" after drinking it. For the baby's digestive system, it is recommended to drink goat milk. Goat milk is better for the stomach than cow milk, and the nutrients it contains are relatively higher than cow milk.

In order to help everyone learn more about lactose intolerance, we hope that everyone can communicate with each other's experiences more often so that we can learn more common sense of life. At the same time, we hope that everyone can read more relevant medical knowledge online when they are free, so that our medical abilities can be further improved.
