Your immune system is your body’s first line of defense against infections, viruses, and chronic illnesses. While genetics and lifestyle factors like sleep, exercise, and stress management play vital roles in immunity, nutrition is just as crucial. The right foods can help strengthen your immune response, speed up recovery, and reduce inflammation.
In this article, we’ll dive into the best foods to boost your immune system, backed by science. You’ll also learn practical ways to incorporate these immune-boosting ingredients into your daily meals.
🔬 How Does Food Affect Your Immune System?
The immune system relies on a steady supply of nutrients to function effectively. Vitamins, minerals, antioxidants, and healthy fats work together to support immune cells, fight off pathogens, and reduce oxidative stress. A diet lacking in essential nutrients can weaken your body’s defense mechanisms, making you more vulnerable to illness.
