Immunity-Boosting Foods

Food alone can't protect against the common cold or flu, and the science isn't yet clear on which nutrients may bolster immunity to reduce your risk of getting sick. But experts agree that a diet rich in a variety of produce, whole grains, lean proteins, and low-fat dairy products―along with adequate sleep, moderate exercise, and minimal stress―contributes to a well-functioning immune system and may promote a faster recovery if you do come down with a cold or flu. Here are some key nutrients and tips that will help increase the likelihood that you'll fly through the winter months in good health.
