Studies showed that garlic has an anti-tumor effect primarily attributed to its bioactive compounds (DATS) (23, 24). Heating destroys the active compound in garlic which is responsible for its anti-cancer effects (25). In “Iowa Women’s Health Study”, garlic was the only food out of 127 food items that showed a significant association with decreased colon cancer risk (26). The study mentioned that for colon cancer, fresh or powdered garlic intake of one or more servings will produce a 35% lower risk (27).
