The study, published in the journal Nutrients, found that walnut consumption was more closely associated with higher energy levels and better concentration, compared to other nuts.

Arab further said that Walnuts have previously been investigated for their role in cardiovascular and cognitive health, and now we see an association with depression symptoms -- providing another reason to include them in a healthy eating plan.
