Walnuts are revered as a symbol of intellectualism since long ago. Since ancient times their kernels have been compared visually with brain! The walnut kernels are enriched with health-benefiting nutrients, especially some fatty acids that are important for great health.
The nuts are edible kernels of the fruits from tree from the Juglandaceae family, in the genus: Juglan. Juglan species plants are medium sized believed to be originating in the mountain ranges of the southern Europe region.
The fruits are ready for harvesting by the autumn, when the thick green hull begins to crack open to expose the hard-shelled walnut that has a light brown color. Each nut features roughly spherical in shape and weights about 15 g and has a single edible kernel inside.
The walnut kernel has two uneven, corrugated lobes, off white in color and covered by a thin, light brown skin. The lobes are partially attached to each other. Oil extracted from the nuts is used in medicine, and aromatherapy (apart from cooking).
