Hazelnut oil is a vegetable oil obtained from hazelnut seeds. It is produced mainly in France, Italy and Turkey, and is recognized for its distinctive hazelnut flavor and nutritional qualities. Hazelnut oil is rich in unsaturated fats, which are considered healthy for the heart and the cardiovascular system. It also contains omega-6 and omega-9 fatty acids, which can help regulate cholesterol and prevent certain heart disease. In addition, it is a source of important vitamins and minerals, such as vitamin E and iron. Hazelnut oil is often used in the kitchen to season vegetable, meat and fish dishes, as well as to prepare sauces and dressings. It can also be used as a condiment, replacing butter or margarine, to spread bread or to add a touch of flavor to the dishes.
