Much like the common cold, diet is connected to the flu through immunity. Diets that are sufficient in energy, micronutrients, and macronutrients are important for maintaining a robust immune system, which will help reduce the risk and severity of common flu infections.[1] Flavonoids (plant compounds that have antioxidant and immunomodulatory properties; found in especially high quantities in tea, chocolate, capers, and oregano)[2] may be a noteworthy nutrient for this purpose.[3]

Diet plays a crucial role in immunity, and adequate energy, micronutrients, and macronutrients help to strengthen the immune system and potentially reduce the risk and severity of flu infections. Additionally, flavonoids — found in foods like tea, chocolate, capers, and oregano — may also contribute positively to immune function.
