Introduction

Children often fall sick more frequently than adults, especially in their early years. This is completely normal because their immune system is still developing. However, good nutrition, healthy habits, and proper care can help strengthen immunity over time.

Pediatricians emphasize that there is no single “magic food” for immunity. Instead, a balanced diet, active lifestyle, good sleep, and hygiene together build a strong defense system.
