Fats are essential for our body. Meaning we need to include them in our diet in order to survive. About 60% of our brain is made up of fat. Choosing the wrong kinds of fats and oils or not treating them properly can lead to increased risk of cancer, diabetes, obesity, and heart disease. The best types of fats are the unsaturated fats, which include monounsaturated and polyunsaturated fats. These fats are important for the body and are known to reduce the risk of heart disease, cancer, and obesity. Monounsaturated fats are liquid at room temperature and exist naturally in unrefined oils (olive oil), avocados, almonds, walnuts, seeds, and unrefined seed oils. Polyunsaturated fats are the essential omega-3 and omega-6 fats that exist naturally in seeds, nuts, legumes, green leafy vegetables, cold water fish, and some grains. The ratio of omega-3 to omega-6 fats that a person should get is 2:1 or 4:1. Omega-3 fatty acids are anti-inflammatory and exist in flax, hemp, pumpkin seeds, walnuts, green leafy vegetables, and cold water fish. Omega-6 fatty acids are in safflower, sesame, sunflower, soy, canola, and corn oils and in meats. Most Americans consume excessive amounts of omega-6 in their diets and not enough omega-3. It is important to keep a balance of these in order to improve health. The other types of fats are the saturated fats and trans fats, these are the fats that are solid at room temperature and are most harmful for your health. Saturated fats exist in animal protein (red meat is the highest in fat), dairy, butter, and lard. Trans fats are synthetically produced and exist in processed foods like fast food, pastries (crisco, margarine), and candies. The best way to avoid these fats is by reducing consumption of commercially processed foods. Knowing what types of fats to use when cooking is important. Fats and oils can get damaged if heated above their melting point and become rancid and harmful to us. Olive oil, for example, has a low melting point of 325 F and should not be used for sautéing, grilling, roasting, or baking at high temperatures. It is recommended to be used without heating like in a salad dressings or drizzled over already cooked foods. Choosing unrefined oils and naturally occurring fats is best. Refined oils usually have a higher smoke point, but are chemically processed and don't provide any nutrients. Here is a list of good quality fats and oils to use and their smoke points:
