What are the health benefits of hazelnuts?

The hazelnut is one healthy nut. It's a good source of vitamin E, an antioxidant that can help protect cells from damage and may help keep your immune system strong. Hazelnut also is low in cholesterol and a source of heart-healthy fats. In fact, eating a handful of hazelnuts a day, or other healthy nuts like almonds or walnuts, may reduce your risk of heart disease. Other research has linked hazelnuts with a lower risk of some cancers, and recently, a large study found a potential link between vitamin E-rich diets and a lower risk of dementia.

Hazelnuts, also referred to as filberts or cobnuts, are the top nut source of those heart healthy monounsaturated fats, which may raise levels of HDL and reduce the risk of clogged arteries. They are also excellent sources of manganese, copper and Vitamin E.

The health benefits of hazelnuts are similar to those of other nuts that provide a high content of monounsaturated fat and arginine. In a recent animal study, the effect of adding hazelnut oil to a diet high in cholesterol was evaluated. Initially, when rabbits were fed a high-cholesterol diet, a number of risk factors for cardiovascular disease increased significantly, including blood levels of oxidized lipids (fats), and levels of LDL (bad) and VLDL (very bad) cholesterol. When the rabbits' high-cholesterol diet was supplemented with hazelnut oil, not only did levels of oxidized lipids, LDL, and VLDL drop, but so did the number of atherosclerotic lesions that had formed in their aortas.

One reason for these very beneficial effects -- besides hazelnuts' high levels of monounsaturated fats -- may be their exceptional concentration of copper, a key component, in the intracellular form, of an important antioxidant enzyme called superoxide dismutase, which disarms free radicals that would otherwise damage cholesterol and other lipids. Just 1-oz of hazelnuts supplies 41 percent of the RDI of copper.
