Walnut tree (common)

Juglans regia

Also known as Persian walnut, European, Carpathian or Madeira walnut.

The story…

Walnut trees originated in Eurasia and are now also grown in California, Chile and New Zealand. They are usually between 20 and 25 metres tall and can reach 150 years of age. Fruits are harvested in September-October, on plants more than ten years old. The wood is used in cabinetmaking, as well as in carving and cutlery, while walnut stain, which is the flesh that surrounds the core and leaves black marks on the fingers, is used as pigment in carpentry.


Nutritional intake

Walnuts, like the oil extracted from them, are very rich in omega-3, which are often missing from our diet: 30 g walnuts provide the daily average amount needed by an adult. It contains vitamins E, B9 and magnesium, as well as fibre, which enables it to lower the blood level of “bad cholesterol”. The nut also holds antioxidants, which may protect against cellular aging and certain cardiovascular diseases.


Contraindicated for people allergic to nuts. In case of persistent symptoms or if you have any doubts, consult a doctor.
