The gastrointestinal function of the elderly over 90 years old must have weakened, so they will not want to eat, and they do not like to eat staple food, etc., but they still need to take in enough nutrients to ensure good health. First of all , you must eat three meals a day, mainly all kinds of porridge, eat millet porridge for breakfast and dinner, eat lean meat porridge for lunch, and make the non-staple food lighter. As I get older, my teeth are bad, and my chewing function is also poor, so I can’t eat many snacks. You can eat some protein powder, soybean powder, black sesame paste, etc. in moderation, and drink some milk or yogurt every day to promote gastrointestinal motility. , enhance body resistance!
