Question

iron is carefully conserved by the body and its absorption is affected by a number of factors. determine whether each factor tends to increase or decrease iron absorption. labels ① drop zones reset all consuming large amounts of calcium increases iron absorption (1/2) decreases iron absorption (2/2) consuming meat, fish, or poultry pregnancy consuming tea with meals adolescent growth spurt taking antacids

Explanation:

• Increases Iron absorption:
• Consuming meat, fish, or poultry: These contain heme iron, which is more readily absorbed, and also enhance non - heme iron absorption.
• Pregnancy: The body's iron needs increase significantly to support the developing fetus, so iron absorption is upregulated.
• Adolescent growth spurt: Rapid growth during adolescence increases the body's iron requirements, leading to increased iron absorption.
• Decreases Iron absorption:
• Consuming large amounts of calcium: High calcium intake can interfere with iron absorption.
• Consuming tea with meals: Tea contains tannins that bind to iron and reduce its absorption.
• Taking antacids: Antacids increase the stomach pH, which reduces the solubility of iron (especially non - heme iron) and thus its absorption.

Answer:

• Increases Iron absorption: Consuming meat, fish, or poultry; Pregnancy; Adolescent growth spurt
• Decreases Iron absorption: Consuming large amounts of calcium; Consuming tea with meals; Taking antacids
