Walnuts

They are rich in phytosterols, they possess high quantities of antioxidants (such as selenium and zinc), they offer a lot of magnesium, potassium, phosphorus, some ferrum and vitamin E. A handful of walnuts offer us the same quantity of vitamin E as ½ cup of olive oil, which leads to the improvement of the blood vessels operation and the reduction of the coronary artery disease. The most important fact might be their content in vitamin K, that is normally produced in the intestines but walnuts offer it in larger quantities. Walnuts are from the richest sources of omega-3 and omega-6 fatty acids, which contribute to the reduction of cholesterol (LDL) and to the anti-aging of the brain cells. They assist in the mental activity and memory improvement, as well as in the fight against depression.
