The high fat content, that delays the digesting could be an explanation. Another possibility is the absence of guilt stimulated stresshormones when eating together with the health care personnel. Diabetic patients can eat all kinds of food, but not all day long. Some sweeties after a low fat meal, can have a major impact on the well-being and a minor impact on the metabolic balance. Extra glucose intake could easily be counterbalanced by extra insulin. Extra fat and energy intake has to be balanced by extra physical activity.

A cross sectional study. The Immunology Clinic at the Pelonomi Hospital in Bloemfontein, South Africa. 90 HIV/AIDS patients in different stages of disease were recruited consecutively from January to May 1995. Sixteen patients were followed up in 1997. The patients were divided into three groups according to their CD4+ T-cell counts, and blood levels of protein, albumin, cholesterol, ferritin, vitamin B12, magnesium, and phosphorus, as well as several micronutrients including vitamin E, vitamin C, beta-carotene and retinol which were determined using standard methods. These values were compared with the normal reference values used in the laboratory, and we tried to correlate these parameters with disease stage, as well as recorded nutr...

A national survey was conducted using questionnaires to illicit information from dietitians on their training and competencies. In 2009, data were collected from both community service dietitians (CSDs) participating in community service programs in primary, secondary and tertiary health care centers in all provinces of South Africa, as well as from their provincial managers (nutrition coordinators). Sixteen (100% response) nutrition coordinators and 134 (80% response) dietitians participated in the quantitative survey. The majority of the CSDs reported that, overall, their academic training had prepared them for most aspects of nutrition service delivery. However, some recommended that academic programs include more training on communi...

We used a multistage proportion to population size method to select thirty-one clusters from all the districts and ecological zones of Lesotho. In each cluster, thirty households were randomly selected and salt samples were collected. Six salt samples from two randomly selected retailers in each cluster, and a total of 107 salt samples from all the commercial entry points in the country were also collected. Lesotho does not produce salt and it imports almost all its salt from South Africa. The salt samples were analysed using the iodometric titration method. The median I concentration of salt was 36.2 ppm at entry point, 37·3 ppm at retail level and 38·5 ppm at household level. At household level only 1·6 % used non-iodised salt and 86·9 % used adequately iodised salt. Of all salt collected at household level, 20·4 % ...

Design: The study employed both quantitative and qualitative research designs. A national survey was conducted using a questionnaire to illicit information on community service dietitians' working environments and the challenges they experienced. Furthermore individual interviews were conducted with a purposively selected subsample of community service dietitians to further explore issues that arose in the survey. Setting: Data were collected from community service dietitians in the public health sector in South Africa. Subjects: Dietitians completing their community service year in 2009. Results: Of the 168 community service dietitians placed in 2009, 134 (80 %) participated in the survey, while five community service dietitians in each province (n 45) were interviewed. Overall the community service dietitians were positive about the community service year and reported that it improved their confidence, skills and competencies. However, they experienced challenges related to the orientation programme, supervision/mentoring, resources available, patient referrals and communication.

Two control areas were included to differentiate between the effect of the education programme and a food aid programme that were implemented simultaneously. Weight-for-age, height-for-age and weight-for-height were summarised using standard deviations from the NCHS reference median. For each of the indicators, the difference in the percentage of children below minus two standard deviations from the reference NCHS median in the initial and follow-up surveys was determined.Subjects:Initially 536 children were measured and, after two years of intervention, 815.Results:Weight-for-age improved in all areas, but only significantly in ...

Although the implementation of these recommendations will vary according to intake of traditional, ethnic and cultural foods, these recommendations apply to all population groups, and should be tailored to individual needs, circumstances and preferences. Objectives • To achieve optimal blood glucose concentrations. • To achieve optimal blood lipid concentrations. • To provide appropriate energy for reasonable weight,

Design: A cross-sectional study. Settings: The Immunology Clinic at the Pelonomi Hospital in Bloemfontein, South Africa. Subjects: Eighty-one HIVaAIDS patients in different stages of disease were recruited consecutively from January to May 1995. Eleven of these patients were followed in 1997. Main outcome measures: Anthropometric data including current weight, height, triceps skinfold thickness, midupper-arm circumference, body mass index and bone-free arm muscle area were collected. Nutrient intake was estimated using a diet history in combination with a standardised food frequency questionnaire. The patients were divided into 3 groups according to their CD4 T cell counts. Results: The men were leaner (BMI 18.9) than the women (BMI 22.7) and patients with a CD4 T cell count`200 (stage III) tended to have the lowest median values for all anthropometric measurements. More than half the patients had a low intake (`67% of the recommended dietary allowances) of vitamin C, vitamin B 6 , vitamin D, vitamin A, calcium, iron and zinc. Conclusions: The results con®rms that HIVaAIDS patients from this population are malnourished. There was, however, no association between disease stage and nutritional status. Nutritional supplementation of HIVaAIDS patients should be considered, as this might lead to improved immune function in these patients.
