Introduction
Your immune system is your body’s defense army, always working hard to protect you from viruses, bacteria, and illness. While sleep, exercise, and stress management play important roles, what you eat every day also has a big impact. The right foods for immunity can help your body stay strong, fight off infections, and recover faster when you’re sick.
In this article, we’ll explore the best healthy foods that are proven to boost the immune system. You’ll also get practical tips on adding these options into your daily nutrition—without complicated diets or strict rules.
