5 Benefits of Zinc When Fighting a Cold

Zinc promotes quick healing.

We've talked about how the zinc we get from natural foods helps our immunity, but did you know that it also helps with cell growth? Zinc even helps our body heal, which is welcomed assistance when it comes to cuts and wounds [source: KidsHealth].

Certainly cuts and wounds aren't a symptom of the common cold -- unless your illness makes you woozy and you slip with a knife while preparing your chicken noodle soup -- but keeping everything else about your health in tip-top shape does seem like a good move when dealing with a cold. After all, even minor things, like a scrape on the finger can send you over the edge when all you want to do is curl up on the couch and ring a bell for assistance.
