For centuries, nuts have been valued for their nutritional qualities and exquisite taste, and their oils have been used not only in cooking but also in medicine.
Nut oil, whether from walnuts or hazelnuts, is a concentrate of nutrients with high energy value and a unique composition.
They are rich in unsaturated fatty acids, including omega-3 and omega-6, which contribute to maintaining heart and vascular health.
These oils also contain antioxidants such as vitamin E and phytosterols, which help combat free radicals and prevent oxidative stress.
In addition, nut oils are rich in magnesium and phosphorus, which are essential for bone tissue and the nervous system.
Nut oils have the following effects:
- Improvement of the cardiovascular system: regular consumption can help lower levels of “bad” cholesterol (LDL).
- Support for brain function: due to the content of omega-3 fatty acids, nut oils positively influence cognitive functions.
- Bone strengthening: magnesium and phosphorus in the composition help strengthen bone tissue.
Choose unrefined, first cold-pressed nut oils to maximize the benefits of antioxidants and healthy fats.
Walnut Oil vs. Hazelnut Oil
Although nut oils have much in common, the differences in composition and properties of walnut and hazelnut oils make them unique, and each type of oil may be more preferable depending on individual goals and needs.
Walnut oil is rich in omega-3 fatty acids, making it an excellent choice for maintaining the balance of omega-3 and omega-6 fatty acids in the diet.
It contains antioxidants such as vitamin E and phytosterols.
Hazelnut oil also contains a lot of monounsaturated fats and a low level of saturated fats, which positively affects the cardiovascular system. But unlike walnut oil, it contains less omega-3 fatty acids.
At the same time, hazelnut oil boasts a high mineral content, such as magnesium and calcium.
It is also rich in vitamin E, which serves as a powerful antioxidant.
