Question
Chapter 19, Problem 28P
Interpretation Introduction
Interpretation: The amount of protein required everyday by a 110 lb gymnast when DRI for protein is 0.8 g/kg should be determined.
Concept introduction:
- DRI is the dietary reference intake. It is different for fat, protein and carbohydrates.
- If weight of the man is X kg, of energy and DRI of a nutrient is Y g/kg, then the amount of nutrient required by the man is
- 1 lb =0.45kg
Given:
Weight of the gymnast = 110 lb
DRI for protein = 0.8 g/kg
