Abstract
In a study of 1700 members of the UK general public in 1992 in which face-to-face interviews were conducted, factors thought important in a healthy diet were (in descending order) more fiber, less sugar, less fat, less salt, and more starchy foods. Of common nutritional terms there was most confidence in explaining the meaning of fiber and least in the meaning of monounsaturated fatty acids. Most nutritional information came from the media but the credibility of this information was low. Fifty-three percent said that a conversation with their general practitioner (GP) was a source of advice they trusted. In a survey of 150 GPs and 50 practice nurses in 1992, lack of confidence was found to be common concerning the meaning of several nutritional terms, especially extrinsic sugars, NSP (nonstarch polysaccharide), and trans fatty acids. GPs were confident they could explain the link between diet and heart disease but were not sure about the value of starch in the diet. Both GPs and practice nurses were dissatisfied with their training in nutrition, both before and after registration. General practice staff thought that personal ill health was the most important motivator for dietary change among their patients. They thought that apathy and dietary conservatism were the most common barriers to people changing their diet. However, the public positioned lack of knowledge as the biggest obstacle. Surveys reported here showed that people’s knowledge of sources of fat, calcium, and iron is often unreliable.
