Vegetable oil is a type of oil that is extracted from various plants, seeds, or fruits. Common sources include soybeans, sunflower seeds, canola, and olive. It is widely used in cooking, baking, and frying due to its high smoke point and neutral flavor. Vegetable oil is also a common ingredient in salad dressings and processed foods. In addition to culinary uses, vegetable oil has applications in non-food industries, such as cosmetics and biodiesel production. It is often considered a healthier alternative to animal fats, as it contains unsaturated fats, which can be beneficial for heart health when consumed in moderation.
