The English walnut, as it is often referred to, is known for its rounded shell and prized kernel.
Walnuts: A Nut of Distinction
Walnuts are renowned for their unique appearance, with their hard shells resembling the shape of a human brain. This has led to the ancient belief in the doctrine of signatures, where foods resembling body parts were thought to have medicinal properties beneficial to those body parts. In this case, walnuts were believed to be good for brain health.

Nutritional Value
Walnuts are celebrated not only for their delicious flavor but also for their exceptional nutritional value.
