Take Probiotics. Probiotics are “good” bacteria that can help keep the body healthy and protect it from “bad” bacteria — and there’s even some thought that taking probiotics may help to prevent cold and flu viruses. In fact, a recent study found that regular use of probiotics kept people healthier and reduced the incidence of upper respiratory infections (like the common cold). Consider eating foods that contain probiotics or taking probiotic supplements to prevent flu.
