These pungent cloves do more than just flavor your food. Garlic also contains allicin, a sulfuric compound that produces potent antioxidants when it decomposes.

A 2001 study in the journal Advances in Therapy found that people who took garlic supplements for 12 weeks between November and February got fewer colds than those who took a placebo. And of those who did get sick, those who took the garlic supplement felt better faster.

Garlic packs the biggest antioxidant punch when eaten raw. Flavor too strong for you? Consider taking aged-garlic extract capsules.
