Health claims and consumers’ behavioral intentions: The case of soy-based food

This research evaluates the impact of two soy-specific health claims (highlighting FDA approval along with scientific results and simply describing scientific results) on stated behavioral intentions toward soy-based food using a survey administered by Ipsos-Observer to a nationally representative web panel in the summer of 2007. Our research design randomly assigned respondents to a health claim. Three ordered probit models (non-soy users; infrequent soy users; regular soy users) show that non-soy users and infrequent soy users who were exposed to either FDA health claim or general health claim are significantly more likely to eat soy-based food products. FDA or general health claim, however, did not change the behavioral intentions of regular soy users. These results suggest that soy consumption status moderates the impacts of health claims on behavioral intentions. However, the impact of FDA health claim did not differ from that of general health claim, indicating that the word ‘FDA’ did not add any additional information to consumers beyond the general health claim.     

Ultrasound technology for better beef price

Sluggish growth in per capita consumption and a downward pressure on beef price at the farm level has required producers to raise cattle that precisely target the meat attributes desired by consumers. Coupled with the consumers' preference for beef with lean tissue and less external fat, the beef packing plants have used the dualistic grading system that emphasizes leanness and palatability; both important to carcass prices. Ultrasound technology can help farmers to produce a carcass with an optimal mix of attributes such as marbling and muscling, and external fat. The results of this study show a high level of accuracy of ultrasound technology in predicting carcass attributes. An estimated hedonic regression model shows that the carcass attributes are reflected on the implicit beef price. Ultrasound technology helps producers to produce carcass with the desired attributes and thus obtain a higher price.     

Association of nutrition concerns and socioeconomic status with exercise habits

The purpose of this study was to examine the association between socio‐economic characteristics and individual health behaviour patterns. Specifically, we looked at how individual demographics (i.e. age, gender, race, marital status, geographic location of households), socio‐economic status (i.e. education, income, children in the households) and respondents’ nutrition concern were related to the major health behaviour (i.e. exercise). Telephone interviews were conducted to collect the data from 2880 US households. A Poisson regression model was estimated to analyse the factors influencing physical exercise habits of adults. Results showed that the key socio‐economic variables influencing the exercise habit of US population were household income, education and family composition. The direct association of nutrition concern with exercise habits implied that health and nutrition programmes should emphasize good eating habit as well as healthy lifestyle.     

Consumer purchase behaviour of irradiated beef products: a simulated supermarket setting

In December 1997, the US Food and Drug Administration approved the use of irradiation to kill harmful bacteria in beef. As a result of limited information about consumers’ potential response to implementation of this technology, a supermarket simulation setting (SSS) test was conducted to assess consumer purchase behaviour. The objectives were to determine consumers’ willingness to purchase irradiated beef products when provided with information at the grocery store level and consumer's perceptions towards irradiated beef. Primary household grocery shoppers (n = 207) in Griffin, Georgia, USA who consumed beef at least twice per week participated in the study. Ground beef, ground chuck, top round steak and rib eye steak were displayed in refrigerated cases in either traditionally labelled packages (non‐irradiated) or in packages labelled as irradiated. Irradiated and non‐irradiated beef had the same unit price. Participants were instructed to purchase two packages of each cut on their first shopping trip; they then shopped a second time after an informative poster about irradiation had been placed in the display cases. The results indicated that irradiation information displayed on the poster at the point of purchase was effective in causing significant change in beef purchase behaviour. The information caused some consumers who had bought traditional packages initially to buy irradiated packages subsequently while others who bought irradiated packages initially subsequently bought traditional packages. Hence, the net effect of the information was minimal. A mean test across form/cut showed that consumers did not differentiate between the ground form and the muscle form in selecting irradiated packages.     

Labelling genetically modified food products: consumers’ concern in the United Kingdom

An online survey method was used to collect data regarding the concern and attitude of UK consumers towards genetically modified (GM) food labelling. Questionnaires were sent to 9000 participants of the online panel via emails, and 2568 consumers completed the online survey. The response rate was 29%. This study found that more than 75% of the consumers questioned were concerned about the labelling of food products with GM ingredients. Eight perceived risks and benefits of agro‐biotechnology were identified to be associated with consumers’ attitude towards GM food labelling. Among them, three were perceived benefits, such as reduced use of chemicals in crop production, improved nutritional content, and increased yields. The five perceived risks were health risks, environmental risks, moral considerations, image of multinational corporations as the primary beneficiaries of biotechnology, and growing control of multinational corporations over farming. While all five perceived risks from GM food played a statistically significant role in shaping the overall attitude towards GM labelling, improved nutritional content due to application of biotechnology was the only benefit that was statistically significant. Age of the respondents was the only demographic variable playing a statistically significant role in shaping the attitude of respondents towards GM food labelling. Older respondents were more likely to be concerned about the existing GM labelling practices than younger respondents.     

Perception of food safety and changes in food consumption habits: a consumer analysis

The relationship between seven types of food safety concerns and the corresponding change in food consumption habits of 236 households in Georgia, USA was evaluated. Results showed a gap between food safety concerns and food consumption habits. Gaps were particularly evident in the cases of pesticide residues, animal drug residues, growth hormones and bacteria. For example, more than 54% of sample households were extremely concerned about pesticide residues, but only 35% actually took extreme precaution in buying items considering this perceived threat. The study indicated that educating consumers about preventive methods to reduce food safety threats will lead to reduced concerns and changes in food consumption habits.     

Meat labels: consumer attitude and meat consumption pattern

This paper addressed consumers’ attitude towards food labels and the influence of different aspects of meat labels on beef, poultry and seafood consumption using data from a national survey in the USA. Approximately 70% of the respondents reported that food labels helped in the purchases of beef and other meat products. While 50% thought that the present level of information on meat labels was about right, about 30% thought that it was insufficient. Similarly, 80, 81, 60, and 80% of the respondents thought that it was very important that meat labels contain information regarding nutrition, ingredients, health claim, and production process respectively. Those respondents who thought that nutrition and ingredient information on food labels were very important also thought that meat labels helped them select beef and other meat products. Consumer preferences for nutrition and ingredient information on food labels were positively related with meat consumption frequency.
