Walnuts benefit out health on so many levels! These nuts are part of the tree nut family, along with Brazil nuts, hazelnuts (filberts), cashews, pine nuts, macadamia nuts, pistachios, and pecans. It would be difficult to overemphasize the potential health benefits related to this food family!
Walnuts are single-seeded stone fruits, which grow from the walnut tree. This tree is native to eastern North America but is now commonly grown in Iran, China, and within the United States in Arizona and California.
