1. They Contain Good fats
Hazelnuts are particularly high in omega-9 fatty acids. These healthy oils play an important role in balancing cholesterol in the body, as well as helping to lower blood pressure and offer protection against coronary heart disease and diabetes. Omega-9 fats contain oleic acid, the main oil found in olive oil, giving them the same heart-healthy, anti-inflammatory action as olive oil.
2. They're Rich in vitamins and Minerals
Hazelnuts have the highest concentration of folate among all the tree nuts. Folate reduces the risk of neural tube birth defects, and is linked to protecting heart health, certain cancers, Alzheimer's disease and depression.
3. They're Rich in Phytochemicals
Snacking on hazelnuts fortifies the body with a variety of phytochemicals including proanthocyanidins, quercetin, and kaempherol. The proanthocyanidins are the same flavonoids that give green tea their health benefits. Proanthocyanidins have shown the potential to protect brain health, improve circulation, and even relieve allergy symptoms.
Hazelnuts provide a high-quality source of protein and fiber. A cup of chopped hazelnuts has a whopping seventeen grams of protein and eleven grams of fiber. They're a good alternate protein source for those who don't eat meat, although other forms of vegetarian protein are needed to provide a complete source of essential amino acids.
5. They Can Potentially Reduce the Risk of Cataracts
A study in rats showed that hazelnuts prevented the formation of cataracts in rats. The cataract was induced by the administration of the chemotherapeutic drug doxorubicin. This protective effect was thought to be due to the natural antioxidants such as Vitamin E and other phytochemicals found in hazelnuts.
