Health-care professionals' perceived trust in and willingness to recommend functional foods: a qualitative study.

The aim of this study was to investigate some Swedish dieticians', registered nurses' and physicians' thoughts about functional foods and their willingness to recommend such foods to patients. The health-care professionals were recruited to participate in one group interview with each profession. Participants were recruited through mailed invitations from primary care centers in Uppsala County district. The interviewed physicians and registered nurses, in contrast to the dieticians, expressed more skepticism and distrust about functional foods, their claimed effects on health and the research documenting these effects. The participating dieticians were more willing to recommend the products to patients than were the participating nurses and physicians. Differences in educational and professional background and level of proficiency in nutrition may have affected the disparate beliefs about functional foods among the interviewed groups. Confusion among patients could be a consequence but further research into these disparities is needed.

Altered food intake and taste perception in children with cancer after start of chemotherapy: perspectives of children, parents and nurses.

GOALS OF WORK: The purpose of this study was to better understand various variables related to food intake and eating problems in children with cancer during their chemotherapy. PATIENTS AND METHODS: Twenty-two consecutively admitted children, diagnosed with cancer and undergoing chemotherapy, participated in this study. Twenty-one of them, their parents and attending nurses participated in semi-structured interviews. Ten of the children underwent a taste acuity test, and recognition thresholds for the four basic tastes were determined. MAIN RESULTS: The shared view of both children and parents was that altered taste was the predominant cause of the eating problems. In contrast, the nurses perceived that nausea was the most important cause of the children's eating problems. In addition, psychological aspects such as learned food aversions and negative attitudes towards hospital food were regarded as important by children, parents and nurses. The taste test showed that the patients had higher thresholds for bitter taste and made more taste recognition errors compared to controls. CONCLUSIONS: Changes seem to exist both in the primary gustatory sense as well as in food perception in paediatric cancer patients undergoing chemotherapy. Single solutions, such as efforts to serve "tasty food", do not suffice alone. A more effective solution may be to combine different strategies and combinations of oral, enteral and parenteral nutrition should be considered to prevent malnutrition.

Nutritional status, dietary energy intake and the risk of exacerbations in patients with chronic obstructive pulmonary disease (COPD).

Loss of body weight, as a result of imbalance between increased energy demand and/or reduced dietary intake, is a common problem in patients with COPD. The aim of this investigation was to examine the relationship between nutritional intake, change in body weight and the risk of exacerbation in patients with COPD. The study comprised 41 patients who were hospitalised because of an exacerbation of COPD. The follow-up period was 12 months. Weight, height and lung function were measured at baseline. At the 12-month follow-up, weight change and current weight were assessed by an interview and nutritional intake was recorded in a food diary for 7 days. An acute exacerbation was defined as having been admitted to hospital and/or making an emergency visit to hospital, due to COPD during the follow-up period. At baseline, 24% of the patients were underweight (body mass index (BMI)<20 kg/m2), 46% were of normal weight (BMI 20-25 kg/m2) and 29% were overweight (BMI>25 kg/m2). Energy intake was lower than the calculated energy demand for all groups. During the follow-up period, 24 of the 41 patients had an exacerbation. A low BMI at inclusion and weight loss during the follow-up period were independent risk factors for having an exacerbation (P=0.003 and 0.006, respectively). We conclude that, in patients who are hospitalised because of COPD, underweight and weight loss during the follow-up period are related to a higher risk of having new exacerbations.

Consumer attitudes towards genetically modified foods.

The present study reports attitudes towards genetically modified (GM) foods among Swedish consumers. A random nation-wide sample of 2,000 addressees, aged 18-65 years, were mailed a questionnaire and 786 (39%) responded. Most of these consumers were rather negative about GM foods. However, males, younger respondents and those with higher level of education were more positive than were females, older respondents and those with lower level of education. A majority of the consumers had moral and ethical doubts about eating GM foods and did not perceive attributes like better taste or lower price beneficial enough to persuade them to purchase GM foods. However, tangible benefits, like being better for the environment or healthier, seemed to increase willingness to purchase GM foods.
