Scientists have found out that consuming walnuts may lower the prevalence and frequency of depression, and improve concentration levels. Researchers from the University of California, Los Angeles in the United States found that depression scores were 26 per cent lower for walnut consumers and eight per cent lower for consumers of other nuts, compared to those who did not eat nuts at all.
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. Lead investigator Lenore Arab has said that Walnuts have previously been investigated for their role in cardiovascular and cognitive health, and now we see an association with depression symptoms.
Researchers examined data from the National Health and Nutrition Examination Survey, which draws from a large sampling of the US population. According to the findings, walnut consumers were more likely to have greater interest in activities, higher energy levels, less hopelessness, better concentration, and greater optimism.
