There are two common species of walnut, the Black Walnut and the English Walnut. The English Walnut is the most commonly consumed.

Health considerations

Walnuts are among the most antioxidant-rich nuts. Walnuts provide protein and some vitamins and minerals, including zinc and B vitamins. Walnuts are primarily fat, the majority of which is polyunsaturated, including Omega-3 and -6 fatty acids. Inclusion of moderate quantities of walnuts in the diet has been associated with improvements in cholesterol and blood lipids. See: Omega-3 fatty acids

Keep in mind

Walnuts are considered tree nuts and thus should be avoided by those with tree nut allergies unless otherwise indicated.
