Is your school cafeteria helping or hurting your kid’s academic performance? Many who are still unwilling to read the research claim that what you eat doesn’t matter very much. They are wrong. Many early studies were not done with a strong experimental protocol or they were done on malnourished kids. But more recent ones have used the “gold standard” in research (blind studies, large sample sizes, cross-over design) and they have found that school nutrition does matter.
