Peanut oil is an edible oil extracted from peanuts. It is commonly used in cooking, baking, and frying, as well as in the production of processed foods, cosmetics, and other products. Peanut oil has a mild, nutty flavor and a light color, and is known for its high smoke point, making it suitable for high-heat cooking methods. It is also low in saturated fats and high in monounsaturated and polyunsaturated fatty acids, making it a healthier alternative to other oils high in saturated fats. Peanut oil is a good source of vitamin E and other antioxidants, which can provide health benefits, including reducing inflammation and improving heart health. However, some people have peanut allergies, and must avoid peanut oil and other products made from peanuts.
