Question

which of the following substances enhances absorption of nonheme iron? select one a. mfp factor b. phytates c. calcium d. polyphenols e. tannic acid

Explanation:

To determine the substance that enhances nonheme iron absorption, we analyze each option:

• Option A (MFP factor): MFP (Meat - Fish - Poultry) factor is known to enhance nonheme iron absorption.
• Option B (Phytates): Phytates are inhibitors of nonheme iron absorption as they bind to iron and reduce its availability.
• Option C (Calcium): Calcium can interfere with nonheme iron absorption and is not an enhancer.
• Option D (Polyphenols): Polyphenols (like those in tea) inhibit nonheme iron absorption.
• Option E (Tannic acid): Tannic acid (found in tea, coffee) is an inhibitor of nonheme iron absorption.

Answer:

A. MFP factor
