Health Benefits of Hazelnuts

Incorporating hazelnuts into the diet can offer multiple health benefits, particularly in improving cardiovascular health, lipid profiles, and providing antioxidant effects. These benefits make hazelnuts a valuable addition to a heart-healthy diet, potentially reducing the risk of cardiovascular diseases and improving overall metabolic health.

Cardiovascular Health

Hazelnuts have been shown to significantly improve cardiovascular health by influencing various biomarkers. A study involving hypercholesterolemic subjects demonstrated that a hazelnut-enriched diet improved endothelial function, reduced LDL oxidation, and decreased inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP) and soluble vascular cell adhesion molecule-1 (sVCAM-1)1. Another study confirmed that hazelnuts, when combined with physical activity, improved lipid profiles by reducing LDL cholesterol and increasing HDL cholesterol, suggesting a beneficial impact on cardiovascular risk2.

Lipid Profile Improvement

Regular consumption of hazelnuts has been associated with favorable changes in lipid profiles. In children and adolescents with primary hyperlipidemia, hazelnut intake led to a reduction in LDL cholesterol and an increase in the HDL/LDL cholesterol ratio, indicating a potential reduction in cardiovascular risk4. Similarly, in mildly hypercholesterolemic individuals, different forms of hazelnuts (ground, sliced, whole) improved HDL cholesterol and reduced total cholesterol and LDL cholesterol levels5.

Anti-Inflammatory and Antioxidant Effects

Hazelnuts also exhibit anti-inflammatory and antioxidant properties. A study on overweight and obese individuals found that while hazelnut consumption did not significantly alter inflammatory markers, it did improve diet quality without affecting body composition3. Additionally, hazelnuts have been shown to reduce oxidative stress markers and improve DNA protection in children with hyperlipidemia, further supporting their antioxidant benefits9.

Impact on Metabolic Health

Hazelnuts may also play a role in improving metabolic health. A study highlighted the potential of hazelnuts to modulate insulin sensitivity and lipid metabolism, particularly when combined with physical activity, which could contribute to reduced cardiovascular risk2. Furthermore, hazelnuts have been found to positively affect the fatty acid composition of erythrocyte phospholipids, which is beneficial for metabolic health4.
