A healthy diet is crucial for the maintenance of health. Therefore, the aim of this work is to evaluate the perceptions towards a healthy diet among the participants with work or studies in areas related to diet and nutrition and those who did not.


Anonymous questionnaire data was collected in a cross-sectional study on a non-probabilistic sample of 902 participants living in Portugal.


The results showed that the participants’ perceptions were, in general, compliant with a healthy diet. However, significant differences were found between gender (p=0.004), between the different civil state groups (p=0.016), between the participants who were responsible for buying their own food and those who were not and also regarding the living environment. The variable area of work or studies also showed significant differences (p=0.001), so that people who had work or studies related to agriculture obtained a higher score. Regarding this variable, the mean values of nutrition and agriculture areas were not statistically different between them, but were statistically different from the mean values of psychology and health areas. The participants who had work or studies in areas showing diet and nutrition-related issues achieved a higher mean score (0.72±0.35) when compared to the participants who did not (0.58±0.30).


However, despite the results, it is important to continue developing campaigns that better communicate nutritional aspects, so that people can increase their knowledge on this subject.
