Cottonseed, sunflower and soybean oil are liquid at room temperature. This is due to their low saturated fat content. You can use each type of oil in salads, fried or baked goods. Each seed oil is high in polyunsaturated fats, such as omega-6, omega-3 and omega-9 fatty acids. Omega-6 and omega-3 are essential fatty acids. Because your body can’t make them, you must get them from your diet.
