Canadians' level of confidence in their sources of nutrition information.

North Americans have a great interest in health and nutrition. However, because sources of nutrition information are vast, the quality of the information varies. We explored the potential benefit of segmenting the Canadian population by geographical location and age in determining the principal sources of nutrition information and level of confidence in these sources. A survey was posted on the Dietitians of Canada website: subjects indicated how frequently they used different healthy eating sources and their level of confidence in the various sources. A total of 870 questionnaires were retained. Magazines, books, the Internet, food labels, and brochures were the most frequently used sources of information. Analyses indicated differences between geographic areas in the use of the media (radio, newspaper, television), dietitians, and naturopaths as sources of nutrition information (p<0.05), and between seven age groups (<18 to 65+ years) in the use of the media (p<0.05). Respondents reported being very confident about nutrition information received from dietitians, physicians, books, the government, and nurses, with some differences occurring between geographic areas (p<0.05).
