A strong immune system is essential to fight off infections and stay healthy, especially during cold and flu season. While no food can guarantee immunity, a balanced diet with key nutrients can strengthen the body’s defenses and reduce the risk of illness. The right foods provide vitamins, minerals, and antioxidants that fuel immune cells, promote healing, and protect against harmful invaders. In this article, we’ll explore the top immune-boosting foods and how to incorporate them into your daily meals.
How Nutrition Supports Immunity
The immune system relies on various nutrients to function effectively. Vitamin C, zinc, antioxidants, and healthy fats all play critical roles in defending the body. Eating a diet rich in whole foods—especially fruits and vegetables—ensures your body has the tools it needs to fight infections, repair tissues, and maintain overall health.
Let’s dive into the best foods that boost immunity and how they work to build stronger defenses.
