Which category includes ex. rice, grains, potatoes, fruits?

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

Answer: (C)

Carbohydrates provide the body with most of its energy, and foods like rice, grains, potatoes, and fruits are classified as carbohydrate-rich. These foods supply energy because they contain starches and sugars that the body breaks down into glucose. Rice, grains, and potatoes are high in starch, a complex carbohydrate that releases glucose gradually for steady energy. Fruits contain natural sugars such as glucose and fructose, offering quick energy along with fiber that helps moderate absorption. While these foods may contain small amounts of other nutrients, their primary role and composition in this context are carbohydrates. In contrast, proteins supply amino acids for growth and tissue repair, lipids store large amounts of energy and come from fats and oils, and vitamins are micronutrients required in smaller amounts for metabolic functions rather than as main energy sources.
