A strong immune system is like a shield, protecting us from harmful bacteria, viruses, and other threats. While a healthy lifestyle, adequate sleep, and regular exercise play key roles, what you eat also significantly impacts your immunity. Fortunately, nature provides an abundance of foods packed with vitamins, minerals, and antioxidants that help keep our defenses strong.
Here’s a comprehensive guide to the best foods that can naturally enhance your immune system and keep you feeling your best.
