Sapphire kernels are encased in a hard shell and resemble small brains due to their convoluted surface. They are packed with essential nutrients, including omega-3 fatty acids, antioxidants, vitamins (such as E and B6), and minerals (like magnesium, copper, and manganese). Regular consumption of walnut kernels is linked to improved heart health, enhanced brain function, and better overall well-being. They can be eaten raw, roasted, or used in various culinary applications, from salads and desserts to main dishes.
