Question
**Question:** Which items or conditions improve iron absorption in the mammalian gut? 1. ○ Vitamin C 2. ○ Compounds in the Allium family, and gastric acid 3. ○ Gastric acid and niacin 4. ○ Gastric acid and Vitamin C --- **Explanation:** This multiple-choice question assesses knowledge of the factors that enhance iron absorption in the digestive system of mammals. Understanding these factors is critical for optimizing dietary iron intake and addressing issues such as iron deficiency anemia. The four choices are: 1. **Vitamin C:** Known to improve iron absorption significantly, especially non-heme iron found in plant-based foods. 2. **Compounds in the Allium family, and gastric acid:** Compounds found in vegetables like garlic and onions may aid in iron absorption, alongside the acidic environment in the stomach. 3. **Gastric acid and niacin:** Gastric acid plays a crucial role in iron absorption, though niacin's role is less direct compared to Vitamin C and compounds in the Allium family. 4. **Gastric acid and Vitamin C:** Gastric acid facilitates the conversion of iron to a more absorbable form, while Vitamin C further enhances this absorption process. **Note:** This information can guide dietary choices and the management of nutritional supplements for better iron absorption.
