But why are walnuts so good for you, and how can you incorporate them into your diet?

What Are Walnuts?

Before we explore the benefits, let’s briefly touch on what walnuts are. Walnuts are tree nuts that originate from the walnut tree, specifically the species Juglans regia. These nuts are encased in a hard shell and have a rich, nutty flavor. They are widely used in both savory and sweet dishes, making them a versatile addition to any meal.
