Question

Peter is 20 months old, weighs 28 lb, and he wants to eat the same food his older brothers do. No baby food for him; he is a big boy now! His mother is worried that this might not be an appropriate diet for a toddler and asked you, the nutrition student, to check it out. Be prepared for a challenge! It’s not easy to think about all the elements that make a healthful diet at the same time. You have to think about kilocalories, Acceptable Macronutrient Distribution Ranges (AMDR, which by the way are different for toddlers than for adults and adolescents), and watch iron (the most common dietary deficit in toddlers) and fiber intake. And that’s just the beginning. Adequate intake of fluids and electrolytes is also critical for a toddler’s health.

AMDR: 1300

Part A:

Calculate what percentage of total energy intake came from each macronutrient.

Part B:

Is Peter’s macronutrient intake within the AMDR for his age?

Part C:

Is Peter receiving enough dietary iron? Assume that he eats the entire portions.

Explanation / Answer

A.

Percentage of total energy intake from each macronutrient is as follows:

Fat 1 gm = 9 calories

Proteins 1 gm = 4 calories

Carbohydrates 1 gm = 4 calories

Alcohol 1 gm = 7 calories

AMDR recommendations (1-3 years):

Fat: 30 – 40%

Protein: 5 – 20%

Carbohydrate: 45 – 65%

Calorie values from the above data are calculated as following:

Fat: 49.7 x 9 = 447.3 calories

Protein: 67.4 x 4 = 269.6 calories

Carbohydrate: 17.07 x 4 = 68.28 calories

Total calories = 785.18

The percentage of total energy intake from each macronutrient is calculated by divining the number of calories from each energy nutrient by total calories and then multiplying the result by 100.

Total energy intake came from each macronutrient is as follows.

Fats: 32%

Carbohydrates: 49%

Protein: 19%

B. Yes, Peter’s macronutrient intake is within the range of AMDR. The macronutrients consumed by Peter exceeds the recommended range by AMDR.

C. Yes Peter receiving enough dietary iron.
