Which of the following decreases the absorption of non-heme iron in the diet?
Show answer and explanation
Correct answer: Tannins in tea and coffee
Tannins, phytates (in grains), and oxalates bind to non-heme iron in the gut, forming insoluble complexes that cannot be absorbed. Conversely, Vitamin C and gastric acid facilitate absorption by keeping iron in its more soluble ferrous (Fe2+) state.
