Walnuts are single-seeded fruits which grow from walnut trees (Juglans regia). Inside a hard shell, the wrinkly appearance of a walnut has a distinctive brain-like look, which is why they’re often nicknamed “brain food”. Walnut trees are one of the oldest tree foods, with evidence showing that humans have eaten them for over 10,000 years.
Walnut producers have done a lot of research on the best ways to grow them without damaging the environment. Walnuts are also a perennial nut, meaning they grow all year round and are able to feed more people versus plants with specific growing seasons.
Walnuts are considered one of the healthiest of all nuts, offering an impressive range of nutritional benefits.
