The Zinc Effect
Increasing zinc intake improves the mental performance of adolescents, concludes a study conducted by the U.S. Department of Agriculture’s Human Nutrition Research Center in Grand Forks, N.D.
In a study of 209 7th graders in Grand Forks, daily consumption of 20 milligrams of zinc boosted students’ performance on visual-memory tests, word-recognition tasks, and activities requiring sustained attention, according to James G. Penland, the researcher at the Grand Forks center who led the study.
