Nut oils are oils extracted from various types of nuts, such as almonds, walnuts, and hazelnuts. These oils are rich in healthy fats, vitamins, and antioxidants, making them popular choices for cooking and salad dressings. They can enhance the flavor of dishes and provide nutritional benefits. In addition to culinary uses, nut oils are also utilized in cosmetics and skincare products due to their moisturizing properties. They can help nourish the skin and improve its texture. However, individuals with nut allergies should avoid these oils, as they can trigger allergic reactions.
