The hazelnut is the fruit of the hazel, small, round, cinnamon-colored shell and white-yellowish flesh, sweet-flavored and rich in oil. The hazel's fruit is small, usually 2cm in diameter, oblong or ovoid and sometimes round, with a tip in the end (apex), with a ligneous and thin pericarp, cinnamon-colored. Hazelnuts are a rich source of unsaturated fat, proteins, carbohydrates, vitamin E, folate, vitamins B pantothenic acid, and biotin. Vitamin E is an antioxidant and a body’s free radicals cleaner, helping to the protection against some types of cancer.
