Walnuts may look simple, but they’re considered one of the **most nutritious nuts you can add to your diet**. Doctors and nutrition researchers often highlight walnuts for their role in supporting **heart health, brain function, digestion, and inflammation control**. These benefits come from walnuts’ unique combination of healthy fats, antioxidants, vitamins, and minerals.
Here’s what doctors say **regular walnut consumption** can help with:
