Assessment of dietary patterns can allow unfavourable intakes to be identified.8 Poor diet quality introduces nutritional inadequacies and is a significant predictor of poorer health status.9While the co

Scholars propose that health behaviours contribute towards cognitive function and maintaining a productive work day.10, 11 The main goal for university students i

It is suggested that the type and variety of foods an individual consumes has an important influence on academic outcomes.14 Diet quality has an association with academic p

9、dly throughout the literature. These themes are: overall diet quality, eating patterns and behaviours, fruit and vegetable intake and convenience food intake. In order to understand how diet quality is linked to academic performance, the literature was searched for relevant articles released in the
10、last ten years. An analysis of terms identified the key words of: “student”, “university student”, “diet quality”, “health behaviour”, “eating pattern”, “academic performance” and “academic achievement”. These were used across the electronic data bases of Cochrane library, Web of science, Pubmed, CI
11、NAHL and Scopus. Although preference was given to recent articles involving university students, the final search was expanded to incorporate sources of all years, as well as children and adolescent population groups. The aim of this review is to critique current literature between diet quality and
12、university student academic performance. Furthermore, it will assess current measures of diet quality, and the significance of other factors that contribute towards overall diet quality.2.0 Diet qualityDiet is a key behavioral risk factor that can be modified to have an impact on health.16 Free livi
13、ng people consume whole foods, which contain both nutrient and non-nutrient substances.17 Dietary patterns have synergistic effects, which provide insights beyond the role of nutrients and single foods.18 For researchers, it can be difficult to quantify the diet, and any established values should on
14、ly be used as an approximation. Diet quality is a composite measure of diet in its entirety, and involves the relationships between food groups.7, 8 This qualitative perspective is an alternative approach to provide more detailed dietary information. It can give an indication to the types of food pe
15、ople consume, and therefore where the nutrients are derived from. Diet quality encompasses the central areas of dietary variety, balance, adequacy, and moderation.19 These have been found to contribute to a nutritious diet and can give a greater understanding of dietary habits. Variety and balance i

Adequacy is attaining the recommended energy intakes to meet nutrient requirements, whilst moderation is regulating the intake of certain foods to prevent harmful effects on health (including convenience foods that are high in sugar and fat).20It is widely recognised that a high quality diet should be safe, able to promote optimal development and reduce the
