The proportion of lactose intolerant people in our population is high, lactose intolerant people can prefer low lactose milk and dairy products. Such as yogurt, cheese, low lactose milk, etc. Lactose intolerant people should avoid drinking milk on an empty stomach. It is recommended not to drink milk on an empty stomach, but to drink milk during the meal, or within 1h or 2h after the meal. Secondly, it is recommended that milk should be consumed with solid food. Thirdly, you should drink milk in small amounts and several times. It is recommended to drink milk in 2 to 3 times a day. If you are lactose intolerant and have no milk drinking habits, start with a small amount of milk (50mI) and gradually increase it. This is mainly due to the lack of lactase in their digestive tract, which prevents the lactose in milk from being completely broken down and absorbed by the small intestine, and the excess lactose remaining in the colon cannot be fermented and used in the colon.
