Although the effects of nutrition on health and school performance are often cited, few research studies have examined the effect of diet quality on the academic performance of children. A new study published in the Journal of School Health studied how good nutrition impacts children’s academic performance by identifying specific dietary factors that are associated with the academic performance. Using multilevel regression methods to examine the associated between indicators of diet quality and academic performance, researchers found that students reporting increased diet quality were significantly less likely to fail the literacy assessment. In particular, students with an increased fruit and vegetable intake and lower caloric intake of fat were significantly less likely to fail the assessment. In particular, students with an increased fruit and vegetable intake and lower caloric intake of fat were significantly less likely to fail a assessment. Dietary fat intake was also demonstrated as important to academic performance. They surveyed 5,000 fifth grade students in Nova Scotia, Canada, gathering information on the dietary intake, height, and weight of each student, and examining socio-demographic variables. Using a food frequency questionnaire, researchers calculated each student’s intake of foods from recommended food groups as well as energy and nutrient intakes. They calculated the diet quality index-international (DQI-I), a composite measure of diet quality. The elementary literacy assessment was used to assess academic performance, requiring students to read a variety of materials and answer written questions based on texts.
