b. List dietary sources of heme and non-heme iron.
, NUTRI 202 EXAM 3 CH 10 BEST STUDY GUIDE WITH
COMPLETE SOLUTIONS 2023 A+ SUCCESS ASSAURED
• Heme: only in meats, fish and poultry
• Nonheme: plant based and enriched foods
c. Discuss the absorption of iron in the body, including the ways to
enhance the absorption of iron.
• heme is absorbed easier than nonheme b/c heme is found
in hemoglobin
• iron absorption increases when iron stores are low
• consuming nonheme iron with vitamin C, with meat,
poultry or fish - - enhances absorption
d. Identify individuals with increased iron requirements
• pregnant women, women ages 19-50
