In a monounsaturated fatty acid, one carbon atom is missing its hydrogen buddies, and in a polyunsaturated fatty acid (PUFA), more than one carbon atom is empty. Because those carbon atoms don't really want to be lonely, they tend to react with other substances, trying to fill up the empty places. This makes them unstable and liable to become toxic, especially in the presence of heat, light and oxygen.
Heat, light, oxygen? These are the same conditions when you expose PUFAs to process, store, and cook with them. By the time a PUFA, like soybean, corn, or canola oil, gets from factory to grocery store to your frying pan and plate, it is denatured and harmful to your health. Stable saturated fats, like butter, natural lard, and coconut oil will hold up under the heat of your skillet and are a much healthier option for cooking.

A note about the most damaging fats of all: hydrogenated, partially hydrogenated, or trans fats
Never eat them. They are unsaturated fats that have been chemically altered to act like saturated fats, but they are bad actors. Far from providing the benefits of natural saturated fats, they wreak havoc on your body. Banish these pretenders from your pantry and your diet.
Remember those crucial roles of dietary fat? If you provide damaged fats to your body, you get damaged cell walls, poor hormone production, and dysfunctional metabolism, such as weight gain.
