Cashews

Cashews are a great source of two brainboosting minerals, zinc and magnesium, Katz explains. Zinc is important because low levels of the mineral are associated with depression, and it may improve memory as well, while magnesium has been shown to help better regulate sleeping patterns and may improve learning skills. Cashews also contain the B vitamin thiamin, which Katz says has been linked to more mental energy and better moods in women, plus vitamin E, which in low levels is linked to poor cognition. Not to mention their creamy, amazing taste.
