What are the AMDR ranges for adults for carbohydrates, fats, and protein?

• A. Carbohydrates 45-65%, fats 20-35%, protein 10-35%
• B. Carbohydrates 30-50%, fats 15-25%, protein 40-60%
• C. Carbohydrates 65-75%, fats 10-20%, protein 5-15%
• D. Carbohydrates 50-70%, fats 20-30%, protein 20-30%

Answer: (A)

The main concept is the AMDR, which sets the recommended percentage of daily calories for carbohydrates, fats, and protein in adults to support energy needs and health. The best answer matches the established AMDR: carbohydrates 45-65%, fats 20-35%, and protein 10-35%. These ranges provide enough energy from carbs, essential fats for bodily functions, and enough protein for maintenance and repair, while keeping intake within limits that help reduce the risk of chronic disease.

Other options fall outside these guidelines. For example, a carbohydrate range near 30-50% is lower than recommended for most adults, a very high protein range like 40-60% exceeds AMDR, and a fat range much lower or higher than 20-35% disrupts the balance. The stated ranges in the correct answer reflect the balanced distribution recommended for healthy adult nutrition.
