An Overview Of Hazelnuts

Hazelnuts, also known as filberts, are edible nuts native to Europe and have been cultivated and enjoyed for their flavour and nutritional benefits for centuries. Today, hazelnuts are widely consumed around the world and cherished for their distinctive taste and versatility.

Appearance: Hazelnuts are small, round nuts that typically measure around 1.5 to 2 centimetres in diameter. They have a hard, woody shell that encloses the edible kernel or meat. The shell is usually light brown in colour and has a rough, textured surface. Once cracked open, the kernel inside is creamy white or pale yellow in colour.

Taste: Hazelnuts have a unique and pleasant flavour that combines nutty, buttery, and slightly sweet notes. Their taste is often described as rich and earthy, with a hint of sweetness. When roasted, hazelnuts develop a deeper, more intense flavour profile, enhancing their natural sweetness and adding a delightful aroma.

The delightful taste and distinct crunch of hazelnuts make them a popular choice for both sweet and savoury dishes. They can be enjoyed raw, roasted, or incorporated into various culinary preparations, ranging from desserts and baked goods to salads, sauces, and spreads.

Health Benefits Of Consuming Hazelnuts

Hazelnuts are packed with essential nutrients that offer numerous health benefits. Let’s explore the detailed advantages of incorporating hazelnuts into your diet:

1. Heart Health

Hazelnuts are rich in heart-healthy monounsaturated fats, specifically oleic acid. Research links this fatty acid to reduced LDL (bad) cholesterol levels and improved cardiovascular health. By lowering LDL cholesterol and increasing HDL (good) cholesterol levels, hazelnuts can help lower the risk of heart disease, stroke, and other cardiovascular problems.

2. Antioxidant Powerhouse

Hazelnuts are a great source of antioxidants, including vitamin E, which according to research, protects cells from oxidative damage caused by free radicals. Studies show that antioxidants help reduce inflammation, prevent chronic diseases, and promote overall health and well-being. The potent antioxidant properties of hazelnuts contribute to their anti-inflammatory effects and may help reduce the risk of chronic conditions such as heart disease, cancer, and neurodegenerative disorders.

3. Weight Management

Despite being calorie-dense, hazelnuts can support weight management. The combination of healthy fats, fibre, and protein in hazelnuts helps increase satiety and reduce hunger cravings, leading to better appetite control. Including hazelnuts as part of a balanced diet can help manage weight by preventing overeating and promoting a feeling of fullness.

4. Brain Health and Cognitive Function

Hazelnuts contain vitamin E, a potent antioxidant that plays a crucial role in maintaining brain health and cognitive function. As per studies, Vitamin E helps protect the brain from oxidative stress and may reduce the risk of age-related cognitive decline, including conditions like Alzheimer’s disease. Consuming vitamin E-rich foods like hazelnuts can support brain health and preserve cognitive abilities.

5. Bone Health

Hazelnuts are a good source of several minerals essential for bone health, including calcium, magnesium, and phosphorus. Research proves these minerals contribute to the development and maintenance of strong and healthy bones. Adequate intake of these minerals, combined with hazelnuts’ vitamin K content, can help prevent bone loss, osteoporosis, and fractures.

6. Digestive Health

Hazelnuts are an excellent source of dietary fibre, which promotes healthy digestion and regulates bowel movements. According to reports by the Harvard School Of Public Health, fibre adds bulk to the stool, preventing constipation and supporting regularity. Additionally, fibre acts as a prebiotic, providing nourishment for beneficial gut bacteria, which supports a healthy gut microbiome and overall digestive well-being.

7. Blood Pressure Regulation

Hazelnuts are naturally low in sodium and high in potassium, minerals that help regulate blood pressure. Scientific studies show that potassium acts as a vasodilator, relaxing blood vessels and reducing the strain on the cardiovascular system. By maintaining healthy blood pressure levels, hazelnuts contribute to heart health and lower the risk of hypertension and related complications.

8. Diabetes Management

Hazelnuts have a low glycemic index, meaning they have a minimal impact on blood sugar levels. The combination of healthy fats, fibre, and protein in hazelnuts helps regulate blood glucose levels, making them a suitable choice for individuals with diabetes or those at risk of developing the condition. Including hazelnuts as part of a balanced diet can help maintain stable blood sugar levels.

9. Eye Health

Hazelnuts contain important nutrients for eye health, including vitamin E, vitamin C, and certain antioxidants like lutein and zeaxanthin. These nutrients help protect the eyes from oxidative stress, reduce the risk of age-related macular degeneration (AMD), and promote overall eye health and visual acuity.

10. Improved Skin Health

The antioxidants found in hazelnuts, such as vitamin E and other phytochemicals, help protect the skin from damage caused by free radicals and UV radiation. Studies show these antioxidants contribute to the maintenance of healthy skin, reducing signs of ageing, promoting skin elasticity, and supporting a radiant complexion.


Hazelnuts offer a range of health benefits, including improving heart health, providing antioxidant protection, aiding in weight management, supporting brain function, promoting bone health, enhancing digestion, regulating blood pressure, assisting in diabetes management, benefiting eye health, and improving skin health. They are a nutrient-dense food packed with healthy fats, fibre, vitamins, minerals, and antioxidants. Including hazelnuts in your diet can contribute to overall well-being and help prevent various chronic diseases.
