In these cases you should eat small amounts of food more often, eat slowly and chew your food well. You should not eat fried or fat food, too hot or too cold, acid fruits or fizzy drinks.
Eat a varied diet, which may include foods rich in calories, such as cookies, biscuits, toasts, olives, nuts, sweets and desserts, all in moderate quantities. As fat use olive oil, and season the food with parsley, coriander, oregano, nutmeg, cinnamon, bay leaf, garlic, onion, lemon and pepper.
Drink 1.5l to 2l of water a day, for wich you can drink fruit juices and teas.
