AMDR for protein as a percentage of total energy for adults?

• A. 5-10%
• B. 15-25%
• C. 25-40%
• D. 10-35%

Answer: (D)

Proteins should contribute a portion of total daily energy within a defined range, guiding how much energy comes from protein while leaving room for fats and carbohydrates. For adults, the accepted range is 10-35% of total energy. This span supports essential amino acid needs and body maintenance without crowding out other energy nutrients needed for daily activity and overall nutrient balance. A lower end like 5-10% would risk insufficient protein intake for maintenance; around 15-25% is reasonable but narrower than the official range; and 25-40% tends to be too high for most adults and could limit intake of fats and carbohydrates essential for other functions. Therefore, 10-35% best fits standard dietary guidelines.
