The body's absorption of micronutrients is somewhat more efficient than the body's absorption of macronutrients O a. The body's absorption of micronutrients is somewhat more efficient than the body's absorption of macronutrients. b. The calcium in spinach, nuts, and seeds is absorbed at a higher percentage than the calcium in milk. ° C. Iron competes with both copper and zinc for absorption across the enterocytes. d. Iron absorption is increased in high-fiber meals and reduced in meals containing vitamin C.

Explanation / Answer

Macronutrients are absorbed 90% when it is present. But micronutrients absorption is not that simple. It needs some other factors, and also depends on age , digestive problems etc. Hence option A is false. Calcium in milk is highly absorbed compared to calcium found in nuts , spinach and seeds. Body cannot utilise the calcium from nuts , spinach seeds because they have high quantities of oxalates which inhibit calcium absorption .So option B is false. Iron absorption is decreased in the presence of fibers and calcium presence increases iron absorption. So, option D is false. Iron competes with all other nutrients for receptors and gets absorbed more compared to other nutrients. Hence option C is true.
