How Hazelnuts Can Help Improve Your Health
Eating hazelnuts may help improve your health in several ways. Here are some of the potential benefits:
Heart Health
Hazelnuts may benefit heart health. A study published in Nutrition Research in 2012 found that eating hazelnuts daily for four weeks led to a significant reduction in total cholesterol and LDL (bad) cholesterol levels. Other studies have shown that hazelnuts may reduce inflammation and improve vascular function, both of which are important for heart health.
Brain Function
Hazelnuts may help improve brain function. A study published in the British Journal of Nutrition in 2008 found that consuming hazelnuts significantly improved cognitive performance in healthy adults aged 18–25. Additionally, hazelnuts are a good source of vitamin E, which has been linked to better brain health.
Weight Management
Hazelnuts may also be beneficial for weight management. A study published in the American Journal of Clinical Nutrition in 2007 found that eating 1.5 ounces (42 grams) of hazelnuts per day for 16 weeks resulted in significant weight loss and improved body composition. This suggests that adding hazelnuts to your diet may help you control your weight.
The Health Benefits of Adding Hazelnuts to Your Diet
In addition to the potential benefits mentioned above, hazelnuts may also offer other health benefits when added to your diet. Here are some of the potential benefits:
Improved Digestion
Hazelnuts are a good source of fiber, which is important for digestive health. A study published in Nutrition in 2016 found that consuming hazelnuts increased the amount of beneficial bacteria in the gut, which may improve digestion and help prevent digestive issues.
Reduced Risk of Cancer
Hazelnuts may also reduce the risk of certain types of cancer. A study published in the International Journal of Molecular Sciences in 2018 found that consuming hazelnuts was associated with a decreased risk of colorectal cancer. The study suggests that hazelnuts may help lower the risk of other types of cancer as well.
Reduced Risk of Diabetes
Hazelnuts may also help reduce the risk of diabetes. A study published in the American Journal of Clinical Nutrition in 2015 found that consuming hazelnuts daily for 16 weeks led to significant improvements in insulin sensitivity and glucose tolerance, two markers of diabetes risk.

A study published in the Journal of the American College of Nutrition in 2006 found that consuming 2 ounces (56 grams) of hazelnuts daily for six weeks led to significant reductions in both systolic and diastolic blood pressure. Additionally, a study published in Nutrition Research in 2012 found that eating hazelnuts daily for four weeks led to a significant reduction in total cholesterol and LDL (bad) cholesterol levels.
Other Potential Benefits
Other studies have found that hazelnuts may have other health benefits. For example, a study published in Plant Foods for Human Nutrition in 2014 found that consuming hazelnuts daily for eight weeks improved skin elasticity and moisture. Additionally, a study published in the Journal of the American College of Nutrition in 2006 found that eating hazelnuts daily for six weeks led to significant reductions in markers of inflammation.
