Hazel

From WikiMD's Food, Medicine & Wellness Encyclopedia

Hazel is a type of tree and shrub, belonging to the genus Corylus, which includes nearly 20 different species. The term "hazel" also refers to the nuts produced by these trees, commonly known as hazelnuts.

Description[edit | edit source]

Hazel trees are deciduous, shedding their leaves in the fall. They typically grow to a height of 12-20 feet, although some species can reach up to 80 feet. The leaves are rounded with a pointed tip, and the edges are serrated. The bark is smooth and gray-brown in color.

The trees produce catkins, which are long, cylindrical flower clusters. The catkins appear before the leaves in the spring. The female flowers are very small and largely hidden in the buds, with only the bright red, 1 to 3 millimeter-long styles visible.

Hazelnuts[edit | edit source]

Hazelnuts are the fruit of the hazel tree. They are encased in a hard shell, which is surrounded by a husk that partially to fully encloses the nut. The nut is roughly spherical to oval in shape, 15–25 millimeters in diameter and 10–15 millimeters in length. It has a sweet, buttery flavor and is rich in oil.

Hazelnuts are used in a variety of culinary applications. They can be eaten raw or roasted, and are a common ingredient in pastries, chocolates, and spreads, such as Nutella. Hazelnut oil, pressed from the nuts, is also used in cooking.

Species[edit | edit source]

There are several species of hazel, including:

Cultivation[edit | edit source]

Hazel trees are relatively easy to grow and can thrive in a variety of soil types, although they prefer well-drained, loamy soil. They do best in full sun to partial shade. Hazel trees are often grown for their nuts, but they are also planted as ornamental trees due to their attractive catkins.

Health Benefits[edit | edit source]

Hazelnuts are rich in nutrients, including vitamins, minerals, protein, fiber and healthy fats. They are particularly high in Vitamin E and B vitamins, including folate. Hazelnuts also contain a significant amount of monounsaturated fat, which can help to reduce levels of bad cholesterol and increase levels of good cholesterol.
