While nuts have already been known to prevent or fight diseases below the neck such as heart disease and cancer, new research shows they also help our brains. A study done at Loma Linda University Adventist Health Sciences Center examined the results of eating six different kinds of nuts.
Pistachios ranked highest in gamma wave response, which is critical for enhancing cognitive processing, information retention, learning, perception and rapid eye movement during sleep.
In contrast, peanuts produced the highest delta response, which is associated with healthy immunity, natural healing, and deep sleep.
Walnuts had the highest concentration of antioxidants.
Almonds, cashews, and pecans presumably fell lower on the benefits scale.
So, I guess the takeaway here is pick your nuts carefully. For better memory, try pistachios. For better sleep, try peanuts.
