Shelled nuts are a very energetic fruit, rich in proteins and monounsaturated fats, as well as minerals such as calcium, phosphorus, potassium and magnesium. Nuts promote vital functions (thanks to zinc, which improves the activity of vitamins) and the lowering of cholesterol (by means of unsaturated fatty acids). They also help strengthen bones. Walnuts in the kitchen are much loved because they are extremely versatile: from the famous nut spread for first courses to delicious cakes, from fillings to pests. Eat plain for a healthy snack or covered in chocolate for the pleasure of a delicious cuddle. Finally, from the walnut husk, a characteristic liqueur is obtained: walnut.
