Polyunsaturated fat

A fatty acid carbon chain, with two or more double bonds taking the place of two or more hydrogen atoms. Many scientists believe that polyunsaturated fats can actually lower the levels of cholesterol in the blood when they are substituted for saturated fat. Unlike monounsaturated fats, polyunsaturates actually lower both low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol. But studies have also proven that an intense amount of polyunsaturates in the diet can increase the risk of cancer. Some oils high in polyunsaturated fat include safflower, soybean, and corn oil.
