RN Nursing · Nutrition · Practice question

Which food groups are included in the United States Department of Agriculture (USDA) food patterns?

Answer & explanation

Correct: Grains, vegetables, fruit, dairy, and proteins.

The United States Department of Agriculture (USDA) food patterns, as reflected in the MyPlate framework and the Dietary Guidelines for Americans, organize food into five primary groups: grains, vegetables, fruits, dairy, and proteins. This classification guides Americans in building a balanced diet that meets nutrient needs while staying within calorie limits. Proteins include a wide range of sources such as lean meats, poultry, seafood, eggs, beans, peas, nuts, and seeds. The dairy group includes milk, yogurt, cheese, and fortified soy beverages. The option listing only fruits, vegetables, and whole grains is incomplete because it omits dairy and proteins. The option listing cheese, vegetables, fruits, citrus, and meat does not reflect the official USDA categories — citrus is a subset of fruits, not a separate group, and cheese falls under dairy. The option listing lean meats, protein, grains, and fruit omits vegetables and dairy entirely. Recognizing the official five USDA food groups is essential for nutrition counseling and for answering public health and dietary guidance questions on nursing examinations.
