Limit Bad Fats
You’ve heard of “bad” fats. Well, here they are—saturated fat and trans fat. Saturated fat receives the bad fat label because it raises LDL (bad) cholesterol and total cholesterol levels, increasing the risk of heart disease and stroke. Saturated fat can only be reduced or limited because it is found in nature and would be virtually impossible to eliminate completely. Trans fats, however, are mostly man made and absolutely can be reduced to nearly zero.
Trans fats do occur naturally in low levels in meat and dairy products, but in the American diet, most of it comes from that formed during the partial hydrogenation of vegetable oils.
Why do trans fats carry the title of “really bad fat”? Trans fats offer a double whammy to your blood lipid profile—in addition to raising your bad cholesterol (LDL) levels, like saturated fat, trans fats also decrease your "good cholesterol" (HDL) levels at the same time. What’s the answer? Replace saturated and trans fats with unsaturated fats naturally found in fish, nuts, and seeds.
