Cooking oil is a fat used in food preparation, primarily for frying, baking, and sautéing. It helps to enhance the flavor of dishes and can also prevent food from sticking to cooking surfaces. Common types of cooking oil include olive oil, canola oil, and vegetable oil, each with its own unique taste and cooking properties. Cooking oils are derived from various sources, including seeds, nuts, and fruits. They contain different levels of saturated and unsaturated fats, which can impact health. Some oils, like coconut oil, are solid at room temperature, while others, like sunflower oil, remain liquid. Choosing the right oil can affect both the taste and nutritional value of meals.
