Which item is a primary source of carbohydrates?

• A. Avocado oil
• B. Meat, fish, and tofu
• C. Cereals, bread and potatoes
• D. Apples

Answer: (C)

Carbohydrates are the body's main energy fuel, so the foods that supply the most carbohydrates are those high in starch and sugars from plants. Cereals, bread and potatoes are classic starch-rich staples, delivering large amounts of carbohydrate per serving and serving as the foundation of many diets for energy. Avocado oil is fats, not carbohydrates. Meat, fish and tofu are mainly protein with little carbohydrate. Apples contain carbohydrates too, but as a fruit their carb content is less about dense energy sources and includes sugars and fiber, not the dominant source like starchy staples. So cereals, bread and potatoes best represent a primary carbohydrate source.
