Explanation

• Guava is rich in vitamin C, which improves the absorption of non-haem iron found in cereals, pulses, and other plant foods.
• Tea contains polyphenols that can reduce iron absorption when consumed with meals.
• Postponing tea until about 1–2 hours after the meal can help reduce its inhibitory effect on iron absorption.
• Combining vitamin C-rich foods, such as guava, citrus fruits, or tomatoes, with plant-based meals is a practical way to improve iron availability.
