Background – National Diet and Nutrition Surveys (NDNS) show fat intake is poorly balanced amongst the UK population, a concern due to the association between fat and cardiovascular disease risk. Exploring the relationship between knowledge and attitudes towards fat and fat intake may help to improve dietary habits. Methods – A retrospective questionnaire was used to identify fat intake, knowledge and attitudes towards dietary fat, and BMI amongst a working population of men and women at a supermarket. 80 participants were recruited, and the data was analysed to identify the relationships between knowledge, attitude, fat intake and BMI. Results – 80 % of participants had varying degrees of positive attitudes. Knowledge of nutritional aspects of fat was generally poor, with 60% of participants answering ≤50% of questions correctly. A relationship between knowledge and fat intake was observed, as participants with poorest knowledge were seen in the moderate and high fat groups, but this relationship was not statistically significant (p=0.101). No significant relationships between fat intake and attitude, fat intake and BMI, or knowledge and attitude were reported from inferential statistical analysis. Conclusions – Attitude was unrelated to fat intake, however, greater knowledge was associated with lower fat intake, but this was not statistically significant. Knowledge, attitude and fat intake were all unrelated to BMI, however, methodological limitations may explain this. The efficacy of targeting nutritional knowledge and attitudes to improve diet quality is questioned from this study’s results. Randomised control trials should be conducted to explore the impact of nutritional education and subsequent dietary intakes.
