Interesting about the walnut tree
The fruits of walnut trees (Juglans) have for at least 10,000 years for humans a meaning as food. Due to their high fat content (> 50%), they are a good source of energy in the past as well as today, even though the importance of high calorie nuts has naturally declined in the present time. Walnuts are considered to be extremely healthy: Among other things, they help with anemia, improve wound healing and reduce water loss in diarrhea. In addition, walnuts contain iron, potassium, zinc and α-linolenic acid, an important omega-3 fatty acid for the human body.
Due to its role as a useful tree, walnut trees are now found in all moderate climates in the northern hemisphere. As a wild tree, walnuts are rather rare. In addition to the use of fruits, walnut has an economic importance. Because of its unique color and aesthetic grain, walnut wood is even considered expensive precious wood.
