The chestnut tree is native to Asia Minor, and it has been cultivated from ancient times. Greeks and Romans spread it all over Europe, and later, it was introduced to America.

The chestnut tree is in no hurry to grow. It begins bearing fruit at age 25 or 30 and reaches its mature age after 100 or 150 years. Some chestnut trees are supposed to have lived more than one thousand years. Human beings pass away too quickly. Trees live much longer than we do! When I see a chestnut tree, besides enjoying its beauty and gentle shadow, I cannot help feeling small before its majestic and ancient appearance.

Who doesn’t feel attracted by the aroma of roasted chestnuts? Chestnut trees also give us a lesson of patience. Their green fruits are protected by a thorny layer, which tells people and animals that the time to open them has not come yet. Only when chestnuts are ripe and can be eaten does this layer open.

  2. They have meager amounts of sodium (1 mg per 100 g of edible part) but a high amount of potassium (710 mg per 100 g of edible portion). They are thus recommended in the diets of people suffering from high blood pressure and heart disease.
