Health-related beliefs and consumer knowledge as determinants of fish consumption.

BACKGROUND: Despite scientific evidence on the positive effects of seafood consumption on human health, the consumption of fish remains below the recommended intake levels for the majority of Europeans. The present study aimed to explore cultural differences in potential determinants of fish consumption: consumers' knowledge and health-related beliefs, as well as the relationship between those variables, socio-demographics and fish consumption frequency, using data from five European countries. METHODS: A cross-sectional consumer survey was carried out in 2004 with representative household samples from Belgium, the Netherlands, Denmark, Poland and Spain. The sample consisted of 4786 respondents, aged 18-84 years, who were responsible for food purchasing and cooking in the household. RESULTS: European consumers had a very strong belief that eating fish is healthy. Consumers' belief that eating fish is healthy, their interest in healthy eating and objective fish-related nutrition knowledge, positively, but only weakly, influenced fish consumption frequency. Subjective knowledge was found to be a stronger predictor of fish consumption than the previously noted factors. Age and education contributed, both directly and indirectly through knowledge, to explain fish consumption behaviour. However, the path coefficients in the estimated model were relatively low, which indicates that fish consumption frequency was also determined by factors other than health-related beliefs and consumers' knowledge. CONCLUSIONS: The findings of the present study suggest that communication should focus on health-related benefits other than fish consumption alone. Communicating that eating fish is healthy and stressing the health benefits of fish alone, as is still commonly performed (e.g. in generic promotion and other types of public information campaigns) will be insufficient to achieve higher levels of compliance with fish consumption recommendations.

Societal aspects of genetically modified foods.

This paper aims to examine some of the reasons behind public controversy associated with the introduction of genetically modified foods in Europe the 1990s. The historical background to the controversy is provided to give context. The issue of public acceptance of genetically modified foods, and indeed the emerging biosciences more generally, is considered in the context of risk perceptions and attitudes, public trust in regulatory institutions, scientists, and industry, and the need to develop communication strategies that explicitly include public concerns rather than exclude them. Increased public participation has been promoted as a way of increasing trust in institutional practices associated with the biosciences, although questions still arise as to how to best utilise the outputs of such exercises in policy development. This issue will become more of a priority as decision-making systems become more transparent and open to public scrutiny. The results are discussed in the context of risk assessment and risk management, and recommendations for future research are made. In particular, it is recommended that new methods are developed in order to integrate public values more efficaciously into risk analysis processes, specifically with respect to the biosciences and to technology implementation in general.
