Reported adoption of dietary fat and fiber recommendations among consumers.

OBJECTIVE: To identify constraints in adopting dietary fat and fiber recommendations. DESIGN: A questionnaire was mailed to a sample of the general population, a convenience sample of persons with heart disease and cancer in 11 states, and registered dietitians in 5 states. The survey included questions on demographic and attitudinal factors that were correlated with specific practices to reduce fat intake and increase fiber intake. SETTING: From the general population sample of 6,206 eligible respondents (return rate of 51.5%), those selected were respondents who indicated that they would adopt a dietary recommendation if it were good for them (n = 2,682). Subsamples from the general population were matched to 362 registered dietitians and 147 persons with cancer or heart disease on selected demographic variables. Factors associated with adoption of specific behaviors were identified. STATISTICAL ANALYSIS PERFORMED: Statistical analysis included chi 2, factor analysis, and analysis of variance. RESULTS: The majority of persons who said they would adopt a fat-reducing behavior if it were good for their health reported practicing that behavior often or usually. More than 60% reported consuming whole grains; however, only 15% reported eating fruits and vegetables frequently. Among the general population sample, those more likely to practice a behavior had the following characteristics: female, college educated, older than 60 years, white, higher income, no children younger than 18 years, perceived health status as excellent, and absence of chronic disease. Registered dietitians and those with chronic disease were also more likely to follow dietary fat and fiber recommendations. APPLICATIONS: Nutrition education messages that lead to increased consumption of dietary fiber need to be developed. Nutrition educators should provide strategies for consumers for increasing use of fruits and vegetables in all meals. Good taste and convenience are critical components. The food industry may assist by providing a wider array of convenience entrees or side dishes that feature produce and whole grains.

Position of the American Dietetic Association: food irradiation.

Food irradiation has been identified a sa safe technology to reduce the risk of foodborne illness as part of high-quality food production, processing, handling, and preparation. Food irradiation's history of scientific research , evaluation, and testing spans more than 40 countries around the world and it has been endorsed or support by numerous national and international food and organizations and professional groups. Food irradiation utilizes a source of ionizing energy that passes through food to destroy harmful bacteria and other organism. Often referred to as "cold pasteurization," food irradiation offers negligible loss of nutrients or sensory qualities in food as it does not substantially raise the temperature of the food during processing. Food irradiation does not replace proper food production, processing, handling, or preparation, nor can it enhance the quality of or prevent contact with foodborne bacteria after irradiation. In the United States, manufacturers are required to identify irradiated food sold to consumers with an international symbol (Radura) and and terminology describing the process on product labels. In addiction, food irradiation facilities are thoroughly regulated and monitored for worker and environmental safety. Members of The American Dietetic Association (ADA) and other food, nutrition, and health professionals have a responsibility to educate consumers, food processors, manufacturers and retailers about the safety and application of the technology. When consumers are educated about food irradiation, many prefer irradiated products because of their increased safety. It is the position of ADA that food irradiation enhances the safety and quality of the food supply and helps protect consumers from foodborne illness. The ADA encourages the government, food manufactures, food commodity groups, and qualified food and nutrition professionals to work together to educate consumers about this additional food safety tool and make this choice available in the marketplace.

Consumer perceptions and concerns about food contaminants.

More consumers are concerned about microbiological hazards than any other area. Pesticide residues generate concern, especially among low income consumers with less formal education. Use of antibiotics and hormones in animal production is considered a serious hazard by fewer consumers. Consumer attitudes are influenced by media coverage. An increasing number of consumers expect food producers and retailers to assume a major role in providing safe food. A majority of consumers express interesting in purchasing irradiated food when specific benefits are described and the percentage increases when irradiation is more fully described. In actual market experiences, irradiated produce and poultry have been well received. Similarly, most consumers are positive toward biotechnology, with greatest support for environmental applications. The scientific community should use the media to reach the public with information identifying risks and protective strategies, including the use of new technology.

On-farm quality assurance programs: a survey of producer and industry leader opinions.

To assess interest in implementing a California dairy quality assurance program, practices and opinions of dairy producers and industry leaders were surveyed by a mailed questionnaire and by focus groups. The majority of the 55 participants in the focus group were dairy producers; processor marketing executives, extension dairy advisors, packinghouse executives, and dairy veterinarians were represented. The consensus among the focus groups was that a quality assurance program should be voluntary, be managed by creameries, and confer an economic advantage to participants. Focus group members listed chemical and microbial food safety (in both meat and milk), environmental health, and animal welfare as issues that should be addressed. Of the 1440 questionnaires mailed with producers' milk checks, 413 were returned. Information was collected regarding opinions and practices pertaining to administration of drugs to animals, medical records and animal identification, culling practices, manure management, cow welfare, and feeding of animal protein. An overwhelming 99% of producers believed they were responsible for the safety of meat and milk leaving the farm. Sixty percent of producers said that they would consider joining a California-specific quality assurance program, whereas 9% indicated that they would not. Producers would be more likely to join if their processor believed it would impart a market advantage and if the program standards were controlled by producers.

Consumer concerns: motivating to action.

Microbiologic safety is consumers' most frequently volunteered food safety concern. An increase in the level of concern in recent years suggests that consumers are more receptive to educational information. However, changing lifestyles have lessened the awareness of foodborne illness, especially among younger consumers. Failure to fully recognize the symptoms or sources of foodborne disease prevents consumers from taking corrective action. Consumer education messages should include the ubiquity of microorganisms, a comprehensive description of foodborne illnesses, and prevention strategies. Product labels should contain food-handling information and warnings for special populations, and foods processed by newer safety-enhancing technologies should be more widely available. Knowledge of the consequences of unsafe practices can enhance motivation and adherence to safety guidelines. When consumers mishandle food during preparation, the health community, food industry, regulators, and the media are ultimately responsible. Whether inappropriate temperature control, poor hygiene, or another factor, the error occurs because consumers have not been informed about how to handle food and protect themselves. The food safety message has not been delivered effectively.

A stage-of-change classification system based on actions and beliefs regarding dietary fat and fiber.

PURPOSE: The objectives of this study were to develop a stage-of-change classification system and to determine the degree to which various adult subgroups have adopted the behavioral changes necessary to achieve a low-fat and/or high-fiber diet as recommended by the Dietary Guidelines for Americans. DESIGN: The study used a mail survey randomly sent to 7110 adults. SETTING: The survey was conducted in 11 states and the District of Columbia. SUBJECTS: The random sample included males and females over age 18. Of the eligible respondents, 3198 (51.5%) were included in this analysis, with 2004 and 2066 unambiguously classified into stages of change for fat and fiber, respectively. MEASURES: Stage of change was defined by an algorithm based on self-reported intent and behaviors to limit fat and/or increase fiber. RESULTS: 45% of the respondents were classified as being in action/maintenance for fat and 38% for fiber. Women, older adults, individuals with advanced education, persons with diet-related chronic disease, people with higher levels of relevant nutrition knowledge and attitudes, and persons who indicated that health concerns were a primary influence on their diet were more likely to be in action/maintenance than other respondents. CONCLUSIONS: The algorithm in this study presents a model that more closely reflects the proportions of the adult population that have achieved low-fat diets and classifies a greater proportion in the preparation stage than classification systems in previous studies.
