Question

according to the acceptable macronutrient distribution ranges (amdrs), which of the following would be recommended for a healthy adult?
a
carbohydrates - 50% of calories
protein - 20% of calories
lipids - 30% of calories
b
carbohydrates - 50% of calories
protein - 50% of calories
lipids - 0% of calories
c
carbohydrates - 20% of calories
protein - 40% of calories
lipids - 20% of calories
water - 20% of calories
d
carbohydrates - 33.33% of calories
protein - 33.33% of calories
lipids - 33.33% of calories

Explanation:

The Acceptable Macronutrient Distribution Ranges (AMDRs) recommend that for adults, carbohydrates should provide 45 - 65% of total calories, protein 10 - 35% of total calories, and lipids (fats) 20 - 35% of total calories. Option D has carbohydrates at 33.33%, protein at 33.33%, and lipids at 33.33% which falls within the AMDR ranges. Option A has protein at 20% (lower end of AMDR), lipids at 30% (within range), but carbohydrates at 50% (also within range but let's check others). Option B has lipids at 0% which is below the AMDR. Option C has protein at 40% (above AMDR upper limit of 35%) and also includes water which is not a macronutrient in terms of calorie - providing macronutrients for AMDR calculations.

Answer:

D. Carbohydrates - 33.33% of calories, Protein - 33.33% of calories, Lipids - 33.33% of calories
