Fruits and vegetables and foods high in polyphenolic compounds such as berries and perhaps walnuts (e.g., approximately one ounce per day for humans), may have a plethora of positive effects on brain function. They may help cognitive, motor, and neuronal functions and positively enhance signaling and neurogenesis. There may also be benefits to the aging brain, helping it to decrease vulnerability to oxidative and inflammatory insults related to aging. (Packer, Lester, et al. Micronutrients and Brain Health (Oxidative Stress and Disease) p 182-184. NY: CRC Press, Taylor and Francis Group, 2009.)
