Walnuts have many health benefits for our veins and heart. They also regulate our blood flow. Research has shown that walnuts cleanse the skin, are hypoglycemic and prevent some tumors.

Thereby it doesn’t matter very much if you opt for naked walnuts or walnuts in-shell, since they have roughly the same proprieties.
