Research: LEE, GEORGIOU and RAAB

Listed in Issue 45

Abstract

LEE, GEORGIOU and RAAB, Department of Food Science and Human Nutrition, Iowa State University, Ames, USA examined the perceived knowledge and attitudes of dietitians regarding the effectiveness and safety of functional foods, nutrient supplements, and herbs.

Background

Methodology

A questionnaire was developed and face-validated after a focus group discussion. A geographically stratified, random sample of 202 dietitians licensed in Oregon (LDs) was surveyed by mail; usable data were collected from 162 LDs (80%). The data were analysed statistically.

Results

LDs considered themselves to be knowledgeable of functional foods and nutrient supplements. More than 80% were confident of the effectiveness of functional foods and nutrient supplements for prevention of illness and treatment of chronic illness, and at least 89% were confident of their safety for these uses. Fewer than 75% considered herbs to be safe and only about 50% were confident of the effectiveness of herbs. Only 10% or fewer LDs considered themselves to be knowledgeable about herbs for prevention and treatment of illness. Interest in training about each of these less-traditional nutrition therapies was high.

Conclusion

Oregon LDs consider themselves to be actively practising in the area of complementary medicine and have a strong desire for further training. The dietetics profession can capitalize on this interest by taking the lead in training dietitians about the role of functional foods, nutrient supplements, and herbs in health.

Comment

In view of these dietitians' poor knowledge and attitude regarding herbs, it is worrying that the authors are recommending LDs to taking a leading role in the prescribing of herbs for health-related problems.
