Question

Quizplus · Accepted Answer

Iron competes with both copper and zinc for absorption across the enterocytes. The other statements are not entirely true: A) The body's absorption of macronutrients (carbohydrates, proteins, and fats) is more efficient than the absorption of micronutrients (vitamins and minerals). B) The calcium in milk is absorbed at a higher percentage than the calcium in spinach, nuts, and seeds. D) Iron absorption is increased in meals containing vitamin C, as it helps convert the iron into a form that is more easily absorbed by the body, and reduced in high-fiber meals, as fiber can bind to iron and reduce its absorption.
