Nuts are a popular snack food due to their delicious taste, nutrient-dense composition, and portability. They come in dozens of varieties and are considered dry fruits with a hard shell and protective husk. Despite being high in fat and calories, nuts are not inherently unhealthy.

A dietitian notes that nuts are nutrient-dense and most Americans could benefit from including more of them in their diet. The U.S. Department of Agriculture provides information on the botanical classification of nuts.
