By focusing on nutrient-dense superfoods, you can give your immune system the boost it needs to stay strong and healthy. In this guide, we’ll dive into some fantastic superfoods that can help keep colds and flu at bay.


Understanding Immunity and Nutrition

To understand why superfoods are so great for your immune system, it helps to know a bit about how your body fights off illness and the role nutrition plays.

How the Immune System Works
