A client asks about foods high in iron to prevent anaemia. Which combination provides the most absorbable (heme) iron?

Correct answer

Red meat and poultry — these provide heme iron, which is absorbed at 15-35% efficiency vs 2-20% for non-heme iron from plant sources

  1. A Spinach and orange juice
  2. B Red meat and poultry — these provide heme iron, which is absorbed at 15-35% efficiency vs 2-20% for non-heme iron from plant sources
  3. C Beans and fortified cereal
  4. D Dairy products and eggs

Why this is the answer

IRON TYPES — HEME vs NON-HEME: Heme iron (from meat, poultry, fish): absorbed at 15-35% efficiency regardless of other foods; best dietary source. Non-heme iron (from plants, fortified foods): absorbed at 2-20%; absorption enhanced by vitamin C and inhibited by calcium, tannins (tea/coffee), and phytates. For iron deficiency anaemia education: recommend lean red meat, dark poultry meat, organ meats (highest heme iron); for vegetarians, combine non-heme iron sources with vitamin C (lemon juice, bell peppers, tomatoes) to maximise absorption. Also teach: avoid tea/coffee with iron-rich meals; cook in cast iron pans (leaches iron into food).
