Corylus avellana
Hazelnuts are a nutrient-dense tree nut widely consumed in Mediterranean diets and associated with cardiovascular and metabolic health benefits. They are rich in healthy fats, antioxidants, and micronutrients, and have been studied in human trials for their effects on lipid profiles, inflammation, and overall cardiometabolic risk.
As part of a balanced, plant-rich diet, hazelnuts contribute to heart health, nutrient intake, and long-term disease prevention.
Hazelnuts are rich in:
- Monounsaturated fats (primarily oleic acid) — supporting heart health
- Vitamin E — a powerful antioxidant
- Magnesium — supporting metabolic and cardiovascular function
- Folate — important for cellular health
- Fibre — supporting gut health
- Polyphenols — contributing to antioxidant activity
This profile makes hazelnuts both cardioprotective and nutritionally dense.
Review
Health benefits are due not only to their richness in healthy lipids (plentiful in unsaturated fatty acids), but also to the presence of a vast array of phytochemicals, such as polar lipids, squalene, phytosterols, tocochromanols, and polyphenolic compounds.
