Explanation

Malnutrition is a condition resulting from an unbalanced diet or insufficient food. If you live for an entire year on Twinkies and diet soda, you will undoubtedly suffer from malnutrition. When you break apart the word malnutrition, it’s easy to remember what it means. You’re probably already familiar with nutrition, which refers to taking in or using food. Add on the prefix mal-, meaning “bad,” and you get a word that means “bad nutrition.” If you suffer from malnutrition, that means you aren’t getting the right balance of nutrients. This can be caused by not getting enough to eat, or it can be caused by not eating enough healthy foods.
