Drinking water before a meal is generally good if it is in small amounts, but drinking large amounts of water is not recommended. Drinking a small amount of water before a meal is generally good to help the food mix well, and at the same time help to increase the feeling of satiety, without affecting the absorption and digestion of food. The human body will secrete a large amount of digestive juices before digesting food, after drinking a large amount of water before meals, the digestive juices are diluted and the food is not well digested, then it is easy to bloating, abdominal pain, burping, belching (hiccups) and so on. Especially when you eat some meat, seafood and other foods that are not easy to digest. Therefore, it is good to drink a small amount of water before meals, but it is not recommended to drink a large amount of water, especially when eating some foods that are not easily digested and absorbed. If you are particularly thirsty, intermittently giving water in moderation several times will usually help to quench your thirst.
