In today’s fast-paced world, immunity has become a buzzword. After the global health challenges of recent years, people now understand the importance of building a strong immune system instead of depending only on medicines.
The truth is, your body already has powerful defense mechanisms. But to keep them sharp, you must fuel them with the right nutrients. In 2025, with modern lifestyle stress, pollution, and digital fatigue, immunity is more important than ever. Let’s explore the best foods that naturally supercharge your immune system.
1. Why Immunity Matters in 2025
