Avoiding citrus fruits and juices, salty or spicy foods, acidic foods, carbonated and caffeinated beverages, and alcohol prevents a sore tongue, mouth or throat from getting worse, according to PearlPoint Cancer Support. It is also best to avoid hot foods to reduce discomfort while eating.
Any food that causes discomfort or pain is best left out of the diet when tongue or other mouth sores are present, maintains PearlPoint Cancer Support. This includes dry foods, such as crackers and crusty breads, and tough meats that are hard to chew. Cooked or canned fruits and vegetables make good substitutes for fruits and vegetables that are crunchy or have touch skins.
Good food choices include soft, bland foods that are easy to chew and swallow, states PearlPoint Cancer Support. Ground meats, eggs and soft dairy products add protein to the diet without irritating the tongue. Drinking plenty of fluids keeps the tongue and mouth moist to avoid irritation. Room temperature beverages are safest although some patients get relief from ice cold choices.
Other safe, nutritious food choices include oatmeal, smoothies, and macaroni and cheese, informs PearlPoint Cancer Support. Cutting food into small pieces, pureeing it in a blender and cooking it until it is very soft help make it easy to get enough nutrition and calories.
