Liquid food refers to food that can be easily swallowed in the mouth. It is liquid or semi-solid and can be swallowed without chewing. Liquid food generally includes soup, porridge, fruit juice, milkshake and so on.

If the doctor suggests that you can only eat liquid food, it may be because your digestive system has problems, or you are undergoing some kind of treatment and need to limit your diet. Liquid food is easy to be digested and absorbed, which can reduce the burden on the stomach and contribute to the recovery and treatment of the body. However, eating only liquid food for a long time will also lead to the lack of some necessary nutrients in the body, so the diet should be adjusted according to the doctor's advice.

When eating liquid food, you should try to avoid adding too much sugar and salt, so as not to burden your body. At the same time, you can also add some digestible protein and vitamins to ensure the nutritional needs of the body. If you are uncertain about the choice and collocation of liquid food, it is recommended to consult a dietitian or doctor.
