Hazelnuts 🌰

What It Is?

Hazelnuts (Corylus avellana), also known as filberts, are edible nuts that grow on hazel trees native to Europe and Asia. They have been consumed for thousands of years and are commonly used in snacks, spreads, and desserts.

Hazelnuts provide healthy fats, fiber, vitamin E, magnesium, and several antioxidant plant compounds. They are particularly rich in monounsaturated fats and vitamin E, both of which have been studied for their potential roles in cardiovascular and cellular health.

Hazelnuts are best known for supporting heart health, brain health, skin health, metabolic balance, and antioxidant protection.
