Dr. La Puma prepares a thick, wintery soup featuring cancer fighting, heart healthy, cholesterol-lowering benefits of cauliflower. Cauliflower helps lower "lousy" LDL cholesterol in two ways. First, it's an excellent source of fiber, which sweeps away LDL. And second, cauliflower contains IC3, a phytonutrient that helps lower the liver's production of one of the main carriers of bad cholesterol by over 50 percent.
