According to experts, it is better to buy nuts not peeled, but in their shells, as they protect against contamination and air access.

The shell should be intact, without spots. It is best to choose a thin shell with a smooth surface, while it should crack easily, and the kernels should be easily separated from the shell.

Without the shell, the shelf life of the product is sharply reduced. From useful, they will become harmful: oxidized unsaturated fats turn into their antipodes – many products of fatty acid oxidation become carcinogens.

But that's not all. Most nuts are covered with a brown shell, the pellicle. It is in this thin skin, which easily peels off the kernels, that the main strength of nuts is concentrated. Most antioxidants and a number of minerals are concentrated in it.

When we remove the shell, the pellicle is damaged and often peels off. In some nuts, which are usually sold white, this happens very easily. But in any case, the process is intensified during sorting, transportation, packaging and storage of all nuts.

Walnut helps the brain work, since the fatty acids in its composition improve memory and have a sedative effect, reducing the effects of stress. Walnut protein is not inferior to animal protein, and due to the enzyme lysine, it is easier to digest. The high concentration of iron in these nuts helps fight anemia and anemia.

Walnuts are useful for diseases of the cardiovascular system: potassium and magnesium in their composition strengthen the walls of blood vessels, normalize blood pressure and lower cholesterol.

However, you need to remember that the product is very high in calories, so the maximum amount of walnuts per day is 100 grams, this is especially important for people with obesity. Remember also that nuts easily cause allergies.
