8 Ways to Stay Healthy This Winter

Like other natural supplements that stimulate your immune system, garlic may decrease the frequency of the common cold—by as much as 64 percent, according to a 2001 study in Advances in Therapy. Participants took garlic pills, but the active ingredients in garlic can be destroyed with cooking and drying. So for maximum benefit, chop or mash a few cloves a day into your food. (Then...chew fresh parsley to get rid of garlic breath. Your lady will thank you.)
