Is there a link between unhealthy eating and school performance?

Research has shown that there is an indirect link between healthy eating and school performance. Young obese children were found to have lower maths and reading scores and in adolescents, lower performance has been reflected in their grades (Hildenbrandt, 2010).

Education advocates would be wise to examine the extensive body of literature confirming the impact of poor nutritional health on academic achievement. Researchers have asserted that when children go hungry undernourished they tend to be irritable and be apathetic. In addition can have too much energy and therefore difficulty in concentrating (Telljohan et al., 2004)
