Diet is connected to ARIs through immunity. Diets that are sufficient in energy (calories), micronutrients, and macronutrients are important for maintaining a robust immune system, which will help reduce the risk and severity of ARIs.[1] Flavonoids, which are plant compounds that have antioxidant and immunomodulatory properties and are found in especially high quantities in tea, chocolate, capers, and oregano[2] may be particularly helpful for maintaining immunity.[3]
