Nutrition knowledge and food choice among black students in South Africa

Objectives: To investigate the relationship between nutrition knowledge and dietary behaviour, and to assess the perceived influences on food selection among Black students in South Africa. Design: Cross sectional study. Setting: University of the North and two semi-urban Secondary Schools. Subjects: 213 second year social science university students, 104 (48.2%) male and 112 (51.9%) female, and 199 Grade 11 secondary school students, 67 male (32.7%) and 132 female (66.3%). Main Outcome Measures: A General Nutrition Knowledge Questionnaire and a Food Choice Questionnaire. Results: Generally, students seemed to have below average nutrition knowledge levels. University students had significantly more nutrition knowledge than secondary school students.

Choosing everyday foods was not associated with dietary recommendations, source of nutrients, and diet-disease relationships. Among both university and secondary school students the three highest food choice factors included health, sensory appeal and mood
