Therefore, it is recommended to consume whole, unroasted kernels with the skin rather than peeled kernels, either roasted or unroasted Eating nuts has been shown to protect the heart In hazelnuts, the high concentration of antioxidants and healthy fats may increase antioxidant potential and lower cholesterol levels in the blood 14 , The results showed that cholesterol, triglycerides and bad LDL cholesterol levels were reduced Participants also experienced improvements to artery health and inflammation markers in the blood.
Moreover, a review of nine studies including over people also saw reductions in bad LDL and total cholesterol levels in those who ate hazelnuts, while good HDL cholesterol and triglycerides remained unchanged Other studies have shown similar effects on heart health, with results demonstrating lower blood fat levels and increased vitamin E levels 14 , 18 , 19 , Moreover, the high content of fatty acids, dietary fiber, antioxidants, potassium and magnesium in hazelnuts seems to help normalize blood pressure In general, eating 29 to 69 grams of hazelnuts per day has been linked to improvements in heart health parameters Among other nuts like pecans and pistachios, hazelnuts have the highest concentration of a category of antioxidant known as proanthocyanidins 7.
Some test-tube and animal studies have shown that proanthocyanidins may help prevent and treat some types of cancers. It is thought that they protect against oxidative stress 22 , Additionally, hazelnuts are rich in vitamin E, another powerful antioxidant that has exhibited possible protection against cell damage that could cause or promote cancer Manganese has shown to help the functions of specific enzymes that could reduce oxidative damage and decrease the risk of cancer 25 , A couple of test-tube studies showed that hazelnut extract could be beneficial in the treatment of cervical, liver, breast and colon cancer 27 , Furthermore, an animal study using a product made from hazelnut skin extract resulted in a decreased risk of colon cancer after the eight-week study period Since most studies investigating the benefits of hazelnuts against cancer development have been done in test tubes and animals, more studies are needed in humans.
Hazelnuts have been linked to reduced inflammatory markers, thanks to their high concentrations of healthy fats. One study investigated how eating hazelnuts affected inflammatory markers, such as high-sensitivity C-reactive protein, in 21 people with high cholesterol levels. Moreover, eating 60 grams of hazelnuts every day for 12 weeks helped reduce inflammatory markers in overweight and obese people Another study examined how eating hazelnuts affected inflammation. It showed that eating 40 grams of hazelnuts may reduce the inflammatory response in healthy people Similarly, 50 people with metabolic syndrome experienced a decrease in inflammation after consuming 30 grams of a combination of raw nuts — 15 grams walnuts, 7.
However, most studies conclude that eating hazelnuts alone is not enough. In order to reduce inflammation, it is also important to follow a calorie-controlled diet Nuts, like almonds and walnuts, have been shown to help reduce blood sugar levels 33 , 34 , Although not abundant, there is research that hazelnuts may also help reduce blood sugar levels. One study explored the effect of hazelnuts on fasting blood sugar levels in 48 people with type 2 diabetes. About half consumed hazelnuts as a snack, while the others served as a control group.
After eight weeks, the hazelnut group did not experience significant reductions in fasting blood sugar levels However, another study gave a combination of 30 grams of mixed nuts — 15 grams walnuts, 7.
After 12 weeks, the results showed a significant reduction in fasting insulin levels Additionally, oleic acid, which is the main fatty acid in hazelnuts, has been shown to have beneficial effects on insulin sensitivity 37 , A two-month study showed that a diet rich in oleic acid significantly reduced fasting blood sugar and insulin levels, while increasing insulin sensitivity, in 11 people with type 2 diabetes It seems that a diet rich in nuts, including hazelnuts, could help lower your blood sugar and increase insulin sensitivity.
Hazelnuts contain several compounds that may help lower blood sugar levels. In hazelnuts, the high concentration of antioxidants and healthy fats may increase antioxidant potential and lower cholesterol levels in the blood.
The results showed reduced cholesterol, triglycerides and bad LDL cholesterol levels. Participants also experienced improvements to artery health and inflammation markers in the blood. Moreover, a review of nine studies including over people also saw reductions in bad LDL and total cholesterol levels, while good HDL cholesterol and triglycerides remained unchanged.
In general, eating 29 to 69 grams of hazelnuts per day has been linked to improvements in heart function. Among other nuts like pecans and pistachios, they have the highest concentration of a category of antioxidant known as proanthocyanidins. Some test-tube and animal studies have shown that proanthocyanidins may help prevent and treat some types of cancers. It is thought that they protect against oxidative stress.
Additionally, they are rich in vitamin E, another powerful antioxidant that has exhibited possible protection against cell damage that could cause or promote cancer. A two-month study showed that a diet rich in oleic acid significantly reduced fasting blood sugar and insulin levels, while increasing insulin sensitivity, in 11 people with type 2 diabetes. It seems that a diet rich in this nut, could help lower your blood sugar and increase insulin sensitivity.
