Groundnut oil, also known as peanut oil, is a vegetable oil extracted from peanuts (Arachis hypogaea). It is commonly used in cooking due to its mild flavor and high smoke point, which makes it suitable for frying, sautéing, and stir-frying. Groundnut oil is rich in monounsaturated fats and has a favorable balance of omega-6 fatty acids, which can support heart health when consumed in moderation. It also contains antioxidants, such as vitamin E, that help protect against oxidative damage. In addition to culinary uses, groundnut oil is employed in various industrial applications and can be used in cosmetic formulations for its moisturizing properties. While it is generally well-tolerated, individuals with peanut allergies should avoid it.
