Find out factors to consider when planning meals for invalids and convalscent?

It depends on the sickness that the invalid is suffering from. Chicken noodle soup is a common food for the sick. It is good to stick with mild foods when preparing meals for sick people. Avoid spicy dishes or food with very distinct flavors. Spicy or strong foods can upset the stomach, especially if you are sick. Also, it is good to eat foods that are not too dense and/or difficult to digest because you want your body to be using it's energy to get better, rather than digest food.
