Wallnuts

A walnut is the edible seed of any tree of the genus Juglans (family Juglandaceae), particularly the Persian or English walnut, Juglans regia. The fruits of trees in the (family Juglandaceae) are often confused with drupes. Still, they are accessory fruit because the outer covering of the fruit is technically an involucre and thus not morphologically part of the carpel; this means it cannot be a drupe but is instead a drupe-like nut. Some fats are healthier than others. Among the healthy kinds are monounsaturated fat and polyunsaturated fat. Walnuts are one of the top foods you can eat as a source of that good polyunsaturated fat, according to MedlinePlus.
