Which category includes ex. meat, eggs, dairy products, legumes, nuts?

• A. Carbohydrates
• B. Lipids
• C. Vitamins
• D. Proteins

Answer: (D)

Proteins are the nutrient category that includes meat, eggs, dairy products, legumes, and nuts because these foods are rich sources of amino acids, the building blocks the body uses to grow, repair tissues, and make enzymes and hormones. Animal products like meat, eggs, and dairy provide all the essential amino acids in enough amounts, making them complete protein sources, while plant-based options such as legumes and nuts contribute substantial protein as well, though some may lack one or more essential amino acids unless eaten in combination. This is why these foods fit into the protein category: their main role in nutrition is to supply the amino acids the body needs for growth and body-wide functions, not just energy or vitamins. Carbohydrates focus on energy, lipids on fats and long-term energy storage, and vitamins are micronutrients needed in smaller amounts. So, proteins is the best fit for these foods.
