Saturated fats and trans fats raise total blood cholesterol levels and low-density lipoprotein (LDL) cholesterol levels, which can increase your risk of cardiovascular disease and type 2 diabetes. Reduce saturated fats and trans fats by cutting use of butter, lard, shortening and margarine when cooking. Consider these tips when cooking and baking: 1. Saute with olive oil instead of butter. 2. Use olive oil in salad dressings and marinades. 3. Use canola oil when baking.
