Are some fats better than others?

Yes. Monounsaturated fats are the healthiest for your body. Nuts -- like almonds, cashews, hazelnuts, and peanuts -- and avocados contain this type of fat. Choose olive or canola oil for cooking. Polyunsaturated fat is the next healthiest fat. This is found in corn oil, safflower oil, soybean oil, and mayonnaise. Use small amounts of foods that contain saturated fats like butter, lard and meat fat, bacon, and shortening. There are lower-fat versions of foods that contain saturated fats, like sour cream and cream cheese. A healthy diet includes less than 30% of calories from fat, with less than 10% of these from saturated fat.
