Feed a cold, starve a fever—right? Well, it's a little more complicated than that, but it turns out some foods can give you a leg up during cold and flu season.

Unsweetened Cocoa Powder

Hope your holiday plans include cocoa. Studies have looked at cocoa's antimicrobial properties and found it boosted immune-cell activity for added protection against influenza.

Olive Oil

Hello, EVOO! Certain extra-virgin varieties have high amounts of particular phenolic compounds that may hinder the growth of pathogenic bacteria. Translation: They help keep bugs at bay.


Sipping tea does more than soothe a sore throat. Some studies suggest the antioxidant properties of certain catechin compounds found in tea can help fight the flu—in some cases, beating back cold viruses as well.
