For researchers, walnuts are the top nut for brain health.
Particularly, for this reason: They have a significantly high concentration of DHA, a type of Omega-3 fatty acid. Some researchers suggest that DHA may be the key to boosting your brain’s performance and preventing age-related cognitive decline.
Researchers also suggest that walnuts and walnut oil may also keep reducing stress. A study published in the Journal of the American College of Nutrition, reports participants who consumed walnuts and walnut oil not only reduced their LDL levels but also showed significant drops in resting blood pressure and, most surprisingly, in their blood pressure response to stress.
