I bought and planted a tiny American Hazelnut 4 years ago. It was so small I wasn't sure it would survive, but it did. Last year was the first year it bore any nuts... a whopping 15 nuts!
This year was much better, probably about 125 nuts! I'm encouraged, and intend to plant more hazels next spring.
Hazelnuts (aka filberts) are used in confections to make pralines, and in some hazelnut paste products (such as Nutella). In the United States, hazelnut butter is being promoted as a more nutritious spread than its peanut butter counterpart, though it has a higher fat content.
Hazelnuts are very high in energy and loaded with numerous health-benefiting nutrients that are essential for optimum health. 100 g of nuts provide 628 calories. The nuts are rich in mono-unsaturated fatty acids like oleic as well as essential fatty acid linoleic acid that help lower LDL or bad cholesterol and increase HDL or good cholesterol.
They are are an excellent source of vitamin E; containing about 15 g per 100 g (providing 100% of RDA). Vitamin E is a powerful lipid soluble antioxidant, required for maintaining the integrity of cell membrane of mucus membranes and skin by protecting it from harmful oxygen free radicals.
The nuts are packed with many of the important B-complex group of vitamins such as riboflavin, niacin, thiamin, pantothenic acid, pyridoxine (vitamin B-6), and folates. They are rich source of minerals like manganese, potassium, calcium, copper, iron, magnesium, zinc, and selenium.
