A complete of 38 research have been included, comprising 21 cohort research, 15 cross-sectional research and a couple of randomized managed trials.

Whereas reasonable consumption of sure dairy varieties confirmed clear advantages, excessive milk consumption confirmed a possible affiliation with poorer verbal reminiscence.
