Vegetable oils are fats derived from the seeds, nuts, or fruits of plants, widely used in cooking, baking, and food preparation. Common types include olive, canola, sunflower, and soybean oil, each offering unique flavors and health benefits. These oils are rich in unsaturated fats, which can help lower cholesterol levels and reduce the risk of heart disease. They are also a good source of essential fatty acids and vitamins, making them a healthier alternative to animal fats. Vegetable oils are versatile, suitable for frying, sautéing, and salad dressings. Additionally, they play a crucial role in various industrial applications, including cosmetics and biodiesel production, highlighting their importance beyond the kitchen.
