Health.com: Superfoods That Fight Colds

Citrus Fruits

Recent research suggests that vitamin C may not be as useful in preventing colds as once thought. However, studies do show that taking the vitamin at the first sign of illness may reduce a cold's duration by about a day, which can feel like a lifetime when you're suffering.

Eating lots of citrus—whether that entails digging in to orange and grapefruit slices, or using lemons and limes in recipes—will provide plenty of this powerhouse nutrient. Don't worry about overdoing it, since it's very hard to overdose on vitamin C. Anything your body doesn't use is just washed right out of your system.
