The walnut is the fruit of the plant of the same name whose ancient origins are Asian: the beneficial properties of the latter have been rediscovered recently, with some studies indicating it as ideal for combating negative cholesterol. From a caloric point of view, the walnut has a truly remarkable contribution, and mainly contains an important quantity of mineral salts and fatty acids. It can be eaten both as a fruit alone and, moreover, it can be used as a particular ingredient to create tasty and refined dishes, especially if combined with special sauces.
