Influence of Nutrition Information on the Attitudes and Knowledge of Dieters Available to Purchase

Reports a study in which a structured questionnaire was used to elicit the attitudes and knowledge of 451 women (18‐35 years), 217 dieters and 234 non‐dieters to nutritional issues. It included questions on frequency of reading labels, attitudes to and likelihood of buying products labelled with qualitative terms, and understanding of nutritional terms. Data were analysed to determine differences between dieters and non‐dieters. Dieters were significantly more likely to read labels, and gave more priority to “low in calories”. Both groups most often ranked “no additives” as most important. “Calories” and “fat” were most often associated with “fattening”, but “energy” and “joule” were less widely recognized. Dieters recognized more energy‐related terms. Significantly, more dieters knew that fat has more calories than sugar,but the majority of both groups thought saturated fatty acids had more calories than polyunsaturated fatty acids. Results indicate dieters to be slightly more knowledgeable, but that confusion remained over a number of issues.
