Popis: Over 2700 subjects were surveyed to determine if a particular disease condition resulted in better knowledge, beliefs and dietary practices in relation to fat and fiber intakes. Using discriminant analysis, it appeared that the presence of disease conditions could affect these aspects of fat and fiber intake, but the contribution was minimal. General overall nutrition knowledge was lower for subjects reporting osteoporosis, and knowledge of specific facts about fiber was significantly lower in hypertensive and heart disease subjects. Dietary practices related to selection of high fat food was poorer in hypertensives than normotensives. Those with heart disease and hypercholesterolemia had better knowledge about fat than those without this condition. Only subjects with heart disease had more appropriate beliefs toward diet fat and health than did other subjects. Dietary practices appeared to be a factor for only two disease conditions. Subjects self-reporting elevated blood cholesterol levels had more appropriate fiber and fat practices, and diabetics had better diet fiber practices than others. Using multiple regression analysis, older subjects had lower fat and higher fiber intakes, whereas those with greater BMI had poorer diet practices with respect to fat and fiber. Furthermore, the analysis indicated that individuals with the belief that fat or fiber intake could affect health and well-being, and those with better nutrition knowledge, had better dietary practices.
