Peanut oil, also known as groundnut oil, is a popular cooking oil made from peanuts. It is widely used for frying and sautéing due to its high smoke point, making it ideal for high-heat cooking. Rich in monounsaturated fats, peanut oil is heart-healthy and helps reduce bad cholesterol levels. Its light, nutty flavor enhances the taste of dishes without overpowering them. Peanut oil is also a good source of vitamin E, an antioxidant that supports skin health and immune function. It’s commonly used in Asian cuisine and is favored for deep-frying because of its stability under heat. Peanut oil is also versatile, being used in salad dressings, marinades, and stir-fries. Additionally, its long shelf life and ability to resist rancidity make it a popular choice for home cooks and commercial kitchens alike.
