Question 2

Discuss niacin equivalents and how they are calculated based on protein intake.

Accepted Answer

​Grading rubric - answer should include the following items:?Assume that 1 g of complete,high-quality protein = 10 mg of tryptophan.This estimate means that an intake of 60 g of complete protein,for example,would provide 600 mg of tryptophan (10 mg tryptophan/1 g protein × 60 g protein = 600 mg tryptophan).Then,because it takes 60 mg of tryptophan to generate 1 mg of NE,600 mg of tryptophan would generate 10 NEs (600 mg tryptophan × 1 mg NE/60 mg tryptophan = 10 NEs).
