There are plenty of common foods that contain high levels of zinc, including chicken, chickpeas, and cashews, to name a few.

Consider adding honey to your water. Studies have shown that honey is an effective cough suppressant and may promote better sleep in children over the age of 2.

Stress management is another helpful tool for supporting both the gut and the immune system, so engaging in meditation, yoga, or other stress-relieving techniques may keep a cold at bay. Avoiding unnecessary inflammatory foods or drinks is an essential component to offsetting a cold. Things like refined sugars, processed foods, alcohol, and tobacco lower the immune response and will only lengthen the duration of the cold, Schwartz tells mbg.
