Consumers' preference for organic foods in the context of food aspects considered important in a consumption decision and socioeconomic variables has been examined in this study. The results indicate that food aspects related to naturalness, vegetarian-vegan and production location were critical enhancing regularity of organic food purchases.While the familiarity food aspect was viewed as a 'no' issue as far as organic food purchases are concerned. Results further indicate that females and young people buy organics on a regular basis. In terms of political affiliation and church attendance, the liberals and those who at least visit places worship once a month will also regularly buy organics.

The use of biotechnology in food production has generated considerable debate involving the benefits and risks associated with its use. Consumer acceptance of genetically modified foods is a critical factor that will affect the future of this technology. Using data from a national survey, this study examines how public acceptance of food biotechnology is related to consumers’ socioeconomic and value attributes as well as the benefits associated with the use of this technology. Empirical results suggest that consumer acceptance of food biotechnology increases considerably when the use of this technology brings tangible benefits for the public. Consumers with different socioeconomic and demographic attributes have diverging views of food biotechnology only when its use brings specific benefits to them. When the use of genetic technology confers no additional benefit, public attitudes towards genetically modified foods are driven primarily by their scientific knowledge, views of scientists and corporations associated with biotechnology as well as public trust and confidence in government.

Using data from a national survey, this study analyses US consumers’ acceptance of genetically modified foods that provide additional nutritional benefits. Using an ordered probit model, this study examines the relation between the willingness to consume genetically modified foods and consumers’ economic, demographic and value attributes. Empirical results suggest that despite having some reservations, especially about the use of biotechnology in animals, American consumers are not decidedly opposed to food biotechnology. Consumers’ economic and demographic variables are only weakly related to their acceptance of food biotechnology, especially when technology involves plant‐to‐plant DNA transfer. However, public trust and confidence in various private and public institutions are significantly related to their acceptance of food biotechnology. Overall, consumer acceptance of bioengineered foods is driven primarily by public perceptions of risks, benefits and safety of these food products.

Extensive research exists on who does or might purchase organic food products, however little research has addressed either who values organic production methods when deciding what to eat, and correspondingly, who does not purchase organics regularly. This paper reports that values about organic farming often do not translate into corresponding stated preferences about organic food consumption behavior. The paradox is examined within the context of the consumers' sociodemographic characteristics as well as through opinions and preferences related to food in their lives.Results show that consumer claims of buying organics and placing importance on organic production systems when deciding what to eat are highly correlated (.472 at 1% significance level; p<. 001). Organic consumers, however, comprise only slightly more than one quarter (27%) of the highly enthusiastic proponents of organic production methods. Our results corroborate existing research that well-educated persons and those who are primary household shoppers purchase organics most frequently. Additionally, women and those who are older, have higher incomes, and are more liberal, as well as respondents who claim food production knowledge also tend to buy organic food regularly.Regression and factor analysis show that those who value organic production systems when deciding what to eat may be ranked in the following order: the religiously observant, older and female respondents, persons of color, and those who claim food production knowledge. Results show that many of these organic system proponents are under-represented as buyers, in particular: the religiously observant, those for whom food plays an integral role in their lives, the less educated, and lower income and older respondents.More attention should be directed to people who value organic production systems yet do not purchase organics. This will enhance understanding of the transaction barriers that impede consumer participation in the organic market. How this population values organic production systems also has implications for the development of public policy related to sustainable and organic agriculture.
