The flu season can be a daunting time, with many experiencing the effects of this nasty virus. But did you know that certain foods can help your body prepare to fight off the flu? By incorporating specific nutrients into your diet, you can fortify your immune system and stave off illness. In this article, we will explore various foods that can help combat the flu, their nutritional benefits, and how to incorporate them into your meals.
The Role of Nutrition in Immune Health
Before diving into the foods that can help fight the flu, it’s essential to understand how nutrition influences our immune system.
