Question

Lorraine is following a vegan diet. She wants to ensure she is consuming sufficient good quality protein. Her EER is 8890 kJ. Besides protein source combining, what do you tell her to aim for (in grams) to meet the upper range of the AMDR?

Answer 1

EER:

• EER is estimated energy requirement.
• EER= BMR x activity factor

As per American dietary recommendation or AMDR

• Carbohydrate: 45-65% of total daily calories
• Fats: 20 -35% of total daily calories
• Proteins: 10-35% of total daily calories

Considering higher values:

• Carbohydrate: 65% of 8890 =5778.5 KJ
• Fats: 35% of 8890 = 3111.5 KJ
• Proteins: 35% of 8890 = 3111.5 KJ

Per gram calories:

• Carbohydrate: 37KJ/g
• Fats: 35% of 8890 = 17KJ/g
• Proteins: 35% of 8890 = 17KJ/g

Thus, each nutrient required in grams:

• Carbohydrate: 5778.5 / 17 = 339.9 g (approx)
• Fats: 35% of 8890 = 3111.5/ 37 = 84.1 g (approx)
• Proteins: 35% of 8890 = 3111.5/ 17 =183 g (approx)
