Citrus
You’ve heard it before: To avoid colds, get plenty of vitamin C. Truth is, it won’t keep most of us from catching one. (It may help if you’re around people who get sick often, like at a day care.) But if you get a lot of it right before you notice symptoms, it may make you feel better and help you get rid of a cold faster. Oranges, lemons, limes — they’re all sources of vitamin C and can be tasty, too.
