The major motivation for food science and nutrition should be sensual features, cost/price balance, and consumer health (sufficient/balanced nutrition). However, there are important differences between theory and reality. Food choice is a complex process influenced by a number of factors related to the product, the consumer, and the consumption context. The role of the consumer in determining the market success of a product is of maximum relevance. Consumer perceptions and preferences are in motion and in change. Understanding and analyzing consumers’ motivation factors, perception and preferences are important both food industry and also governments. In this study, some of these factors were discussed and aimed to identify them with reasons.展开更多

This was a qualitative cross-sectional study with 83 adolescents from a public school in the city of S?o Paulo. The participants answered the following question: During the school break do you usually eat or drink something? Please justify your answer. The adolescents’ answers were analyzed through a Brazilian qualitative technique called Discourse of the Collective Subject. The ideas were: School Meal Program (36.2%), don’t eat anything (26.7%), bring from other establishments (20.1%) and drink water or juice (17.1%). The adolescents who chose the School Meal Program claimed they had no other options. On the other hand, the participants who refused the meal did so because they disliked it and as a result brought snacks from home or food markets. The Discourse of the Collective Subject helps the investigator to understand the ideas related to food and nutrition of a collectivity.展开更多

A total of 571 consumers, interviewed directly after grocery shopping, were classified as conventional, occasional organic or regular organic consumers depending on the number of organically produced items bought. In order to gain encompassing insights on the differences between the ROC and OOC consumer groups, a large set of psychological and socio-demographic factors was studied. They differ with respect to general food choice motives with OOC placing significantly less importance on animal welfare, food security, environmental protection and more importance on caloric content, convenience and price compared to ROC;with respect to beliefs about the consequences of organic food consumption OOC expect greater expense, less choice, no increase in vitamins and no improvement in taste compared to ROC, and finally OOC show a less positive attitude, weaker social norms and lower intentions of buying organic food regularly in the future and give a lower importance in their lives to protection of the environment. OOC finally prefer different grocery stores and use a larger variety of stores than ROC.展开更多
