Question

1 of 6 Part C Iron Absorption new diet plan contains 3.3 mg of heme iron and 17.5 mg of non-heme iron. What is the amount of biologically available iron? Round the answer to the first decimal place. - View Available Hint(s) Hint 1. Heme and non-heme iron Heme iron is a part of hemoglobin and myoglobin; it is found only in animal-based foods, such as meat, fish, and poultry Non-heme iron is not a part of hemoglobin or myoglobin; it is found in animal-based and plant-based foods. Hint 2. Iron absorption rates Heme iron: 15% availability Non-heme iron: 5% availability mg Submit Request Answer / 2 Next > Provide Feedback 3:19 PM 4/16/2018

Explanation / Answer

Answer

Diet

3.3mg Heme Iron

17.5mg Non heme Iron

Absorption Rate

15% for Heme Iron

5% for Non Heme Iron

Biologically Available Iron = (Dietary Intake of Iron X Absorption Rate)/100

Heme Iron Available = (3.3x15)/100 = 0.495 mg

Non Heme Iron Available = (17.5x5)/100 = 0.875 mg

Answer) Total Biologically available Iron = 0.495+0.875 = 1.37 mg
