Using data from a national survey, this study examines public acceptance of food biotechnology by modeling consumers' willingness to buy genetically modified foods. Empirical results suggest that younger, white, male and college educated individuals are more likely to accept food biotechnology. However, consumers' views about scientists and biotechnology companies, and their trust and confidence in government regulators, have greater impacts on their acceptance of genetically modified foods than their economic and demographic attributes. Overall, consumers view food biotechnology as a risk-benefit issue rather than an ideological issue. There is some evidence of regional differences in the acceptance of bioengineered food products.
