This bulb has been used for centuries as both food and medicine. These days, garlic is used to treat conditions ranging from high blood pressure, high cholesterol, heart disease, and heart attack to certain types of cancer— but the benefits aren’t just for such big issues.

Make It Mediterranean — Your Action Plan
Not a fan of stinky fingers after chopping garlic? No need to pass on its benefits. Garlic can also be consumed as a powder or extract, and most studies suggest similar benefits, regardless of form. As a prebiotic, garlic may also offer digestive benefits by acting as fuel for probiotics found in other foods, so pair them with foods like yogurt (like in this recipe for greek yogurt and garlic dip) to help them work their magic. For an easy way to work in garlic, add a few cloves to almost any savory sauce recipe, or create a meat rub before tossing steaks (or chicken, or seafood) on the grill. Garlic is also an easy add-in for cooked greens and other veggies, and its flavor boost makes it easier to cut down on salt. Just be warned— garlic burns easily, and becomes very bitter when burnt, so add it to the pan last to avoid a catastrophe. But before putting this blub on the ultimate pedestal, it’s worth noting much of the research surrounding garlic has focused on the Mediterranean diet as a whole— which is high in fresh produce (like garlic), whole grains, healthy fats, and (score!) wine. Because the Mediterranean diet in general may reduce cancer risk, it’s hard to know whether the garlic alone is to thank for the benefits noted in other studiesDiet and cancer risk in Mediterranean countries: open issues. La Vecchia, C., Bosetti, C. Istituto di Ricerche Farmacologiche, Mario Negri, Milano, Italy. Public Health Nutrition, 2006 Dec;9(8A):1077-82.. Garlic may also have some unexpected interactions with certain drugs, like those used to treat HIV, so those on prescriptions might want to double-check with a doc before going garlicky.
