May Be Good for the Heart

It has been proven that eating nuts protect the heart. The high concentration of antioxidants and good fats in hazelnuts may boost antioxidant potential and lower blood cholesterol levels. A month-long study of 21 persons with elevated cholesterol levels found that hazelnuts accounted for 18-20% of their total daily calorie intake. The findings revealed that cholesterol, triglycerides, and harmful LDL cholesterol levels had been lowered. Participants also saw changes in their vascular health and inflammation markers in their blood.

Furthermore, a meta-analysis of nine research involving over 400 people found that eating hazelnuts reduced harmful LDL and total cholesterol levels while leaving good HDL cholesterol and triglycerides unaltered. Other studies on heart health have found similar findings, with lower blood fat levels and higher vitamin E levels. Furthermore, hazelnuts' high quantity of fatty acids, dietary fiber, antioxidants, potassium, and magnesium appears to help stabilize blood pressure. Eating 29 to 69 grams of hazelnuts per day has been associated with improvements in heart health measures in general.
