Consumer Quality Certifications & Adulteratio
- Dietary Enhancers of Non-Heme Iron Bioavailability:
- Non-heme iron from plant sources exists predominantly as insoluble ferric iron (Fe$^{3+}$) that is poorly absorbed ($\lt 5\%$).
- Enhancing Factors:
- Ascorbic Acid (Vitamin C): Found abundantly in citrus fruits like (A) Lemon and (D) Oranges; reduces ferric iron (Fe$^{3+}$) to soluble, bioavailable ferrous iron (Fe$^{2+}$) and forms soluble chelates that resist intestinal alkaline precipitation.
- Meat, Poultry, and Fish (MPF Factor): (E) Meat contains cysteine-rich polypeptides that dramatically stimulate non-heme iron uptake.
- Cereals (phytates) and green leafy vegetables (oxalates) contain potent anti-nutritional inhibitors that bind iron.
- Conclusion: (A), (D) and (E) only (Option 2).
Correct option: (2) (A), (D) and (E) only,
