"Eat dry beans, split peas, lentils and soya regularly": a food-based dietary guideline

The objective of this paper is to review recent scientific evidence to support the food-based dietary guideline (FBDG): “Eat dry beans, split peas, lentils and soya regularly”. In this review, legumes are synonymous with the term “pulses”, while soy beans are classified as “oilseeds”. The FBDG was originally introduced to address both under- and overnutrition in South Africa. The nutrient and non-nutrient content, results of recent epidemiological and intervention studies on health effects, recommended intakes and barriers to consumption are briefly reviewed. Legumes are rich and economical sources of good-quality protein, slow-release carbohydrates, dietary fibre (non-starch polysaccharides), various vitamins and minerals and non-nutritive components which may have several beneficial health effects. Pulses have a low energy, fat and sodium content. Therefore, legumes contribute to dietary adequacy, while protecting against noncommunicable diseases through many mechanisms. Evidence is presented that concerns about excessive flatulence from eating beans may be exaggerated, and that there is individual variation in response to different bean types. It is recommended that nutritionists should aggressively encourage consumers to consume more legumes. They should also be advised to evaluate different legume varieties to minimise undesirable symptoms. More research is needed to assess gastrointestinal responses between types of available and consumed legumes in South Africa. The FBDG should be tested in different population groups to determine how to maintain legumes as a traditional food. Increasing familiarity with legumes could help to increase the likelihood that they may be incorporated more regularly into the diet.Department of HE and Training approved lis

The association between childhood environmental exposures and the subsequent development of Crohn's Disease in the Western Cape, South Africa

BACKGROUND: Environmental factors during childhood are thought to play a role in the aetiolgy of Crohn's Disease (CD). However the association between age at time of exposure and the subsequent development of CD in South Africa is unknown. METHODS: A case control study of all consecutive CD patients seen at 2 large inflammatory bowel disease (IBD) referral centers in the Western Cape, South Africa between September 2011 and January 2013 was performed. Numerous environmental exposures during 3 age intervals; 0-5, 6-10 and 11-18 years were extracted using an investigator administered questionnaire. An agreement analysis was performed to determine the reliability of questionnaire data for all the relevant variables. RESULTS: This study included 194 CD patients and 213 controls. On multiple logistic regression analysis, a number of childhood environmental exposures during the 3 age interval were significantly associated with the risk of developing CD. During the age interval 6-10 years, never having had consumed unpasteurized milk (OR = 5.84; 95% CI, 2.73-13.53) and never having a donkey, horse, sheep or cow on the property (OR = 2.48; 95% CI, 1.09-5.98) significantly increased the risk of developing future CD. During the age interval 11-18 years, an independent risk-association was identified for; never having consumed unpasteurized milk (OR = 2.60; 95% CI, 1.17-6.10) and second-hand cigarette smoke exposure (OR = 1.93; 95% CI, 1.13-3.35). CONCLUSION: This study demonstrates that both limited microbial exposures and exposure to second-hand cigarette smoke during childhood is associated with future development of CD

The Association between Race and Crohn's Disease Phenotype in the Western Cape Population of South Africa, Defined by the Montreal Classification System

BACKGROUND: Inter-racial differences in disease characteristics and in the management of Crohn's disease (CD) have been described in African American and Asian subjects, however for the racial groups in South Africa, no such recent literature exists. METHODS: A cross sectional study of all consecutive CD patients seen at 2 large inflammatory bowel disease (IBD) referral centers in the Western Cape, South Africa between September 2011 and January 2013 was performed. Numerous demographic and clinical variables at diagnosis and date of study enrolment were identified using an investigator administered questionnaire as well as clinical examination and patient case notes. Using predefined definitions, disease behavior was stratified as ‘complicated’ or ‘uncomplicated’. RESULTS: One hundred and ninety four CD subjects were identified; 35 (18%) were white, 152 (78%) were Cape Coloured and 7(4%) were black. On multiple logistic regression analysis Cape Coloureds were significantly more likely to develop ‘complicated’ CD (60% vs. 9%, p = 0.023) during the disease course when compared to white subjects. In addition, significantly more white subjects had successfully discontinued cigarette smoking at study enrolment (31% vs. 7% reduction, p = 0.02). No additional inter-racial differences were found. A low proportion of IBD family history was observed among the non-white subjects. CONCLUSIONS: Cape Coloured patients were significantly more likely to develop ‘complicated’ CD over time when compared to whites

Perceived effect of warning label on parental food purchasing and drivers of food selection among South African parents–An exploratory study

Household food purchasing decision is a complex process influenced by factors such as marketing, cost, children food preference and parental choices. Most food products targeted toward children are unhealthy and are aggressively marketed to increase desirability among parents and children making healthier food selection even harder. The warning label (WL) is identified as a simple front-of-package labeling format that assist consumers to easily identify unhealthy foods and reduce their purchasing. This was a qualitative study that aimed to investigate the perceived eect of the warning label (WL) on parental food purchasing and drivers of food selection among parents. The study was conducted in a mainly rural part of South Africa, in Limpopo Province.Household food purchasing decision is a complex process influenced by factors such as marketing, cost, children food preference and parental choices.

A comparative analysis and evaluation of the naturopathic curriculum in South Africa

Naturopathy has been taught at tertiary level in South Africa (SA) for 18 years. This research paper examines the naturopathic curriculum to determine whether it is benchmarked to international standards and meets the needs of graduates in practice. It is the first research paper that critically reviews the curriculum of a complementary alternative medicine profession taught at a higher education institution (HEI) in SA.To critically review the naturopathy curriculum taught at an SA HEI. Methods. This research used a sequential two-stage qualitative methodology. In stage one, a comparative document analysis was conducted using the curriculum recommended by the World Health Organization (WHO), the World Naturopathic Federation (WNF) and the University of the Western Cape. Stage two consisted of a graduate review of the curriculum. Eighteen graduates participated in the review by providing input on all the subjects in the curriculum via email. The responses were summarised and thematically analysed

South African consumers’ perceptions of front-of-package warning labels on unhealthy foods and drinks

Front-of-package labeling (FOPL) is a policy tool that helps consumers to make informed food choices. South Africa has not yet implemented this labeling system. The aim of this study was therefore to explore adult South African consumers’ perceptions of front-of-package warning labels on foods and non-alcoholic beverages (referred to as drinks in this paper) and their insights into features that could influence the effectiveness of the warning label. Using a qualitative approach, the study purposively selected consumers diversified by urbanization, gender, socioeconomic status, and literacy. We collected data from a total of 113 participants through 12 focus group discussions. Data were systematically coded and divided into five themes namely, positive attitudes toward warning labels, perceived benefits of warning labels, perceived behavior modification, perceived beneficiaries of warning labels, and effective attributes of warning labels

Perceived effect of warning label on parental food purchasing and drivers of food selection among South African parents–An exploratory study

Household food purchasing decision is a complex process influenced by factors such as marketing, cost, children food preference and parental choices. Most food products targeted toward children are unhealthy and are aggressively marketed to increase desirability among parents and children making healthier food selection even harder. The warning label (WL) is identified as a simple front-of-package labeling format that assist consumers to easily identify unhealthy foods and reduce their purchasing. This was a qualitative study that aimed to investigate the perceived effect of the warning label (WL) on parental food purchasing and drivers of food selection among parents. The study was conducted in a mainly rural part of South Africa, in Limpopo Province. Data were collected from 44 adult participants, all parents with children aged below 16 years selected using the snowball sampling method. Seven focus groups diversified according to age, literacy, income and urbanicity were utilized for data collection. Using a focus group discussion guide, parents were shown images of six products (crisps, soda, juice, biscuits, cereals, and yogurt) superimposed with the WL and questions asked were based on those images. Thematic analysis revealed that although some parents felt undeterred by the WL, some felt they would alter their food purchasing in the presence of the WL. Other parents felt they would reduce the frequency or the amount purchased or completely stop purchasing labeled products for their children. Motives behind perceived behavior modification included children's health being perceived as a priority and labeled products being viewed as unhealthy. Factors such as pressure from children, taste, poor nutrition knowledge and affordability seemed to influence parental food selection. These findings have important policy implications by providing evidence to policymakers that the WL may alter parental food purchasing and also provide insight into drivers of food selection among South African parents

Child-directed marketing on packaged breakfast cereals in South Africa

Abstract Objective: Childhood obesity is on the rise in South Africa (SA) and child-directed marketing (CDM) is one of the contributing factors to children’s unhealthy food choices. This study assessed CDM on packaged breakfast cereals available in SA supermarkets and their nutritional quality. Design: Photographic images were examined in a descriptive quantitative study. A codebook of definitions of CDM was developed for this purpose. REDCap, an online research database, was used for data capturing and SPSS was used for data analyses including cross tabulations and one-way ANOVAs. Setting: The current study was set in the Western Cape province of SA. Subjects: Photographic images of all packaged breakfast cereals sold in major retailers in the Western Cape province of SA in 2019 were studied. Results: CDM strategies were classified as direct (to the child) or indirect (through the parent). A total of 222 breakfast cereals were studied, of which 96.9% had a nutritional or health claim, 95.0% had illustrations, 75.2% had product and consumption appeals, 10.8% had characters, 10.8% consisted of different appeals, 8.6% alluded to fantasy and 7.7% had role models. In breakfast cereals with direct CDM the protein and fibre content were significantly lower than in breakfast cereals without direct CDM. This study found a significantly higher total carbohydrate and total sugar content in breakfast cereals with direct CDM than those without direct CDM. Conclusion: CDM was highly prevalent in breakfast cereals sold in SA. Regulations to curb the marketing of packaged foods high in nutrients of concern is recommended

The effect of legislation on the treatment practices and role of naturopaths in South Africa

In South Africa naturopaths have been practising for over half a century. Over this period, changes in legislation have resulted in different levels of training and registration processes - which has impacted on the profession in various ways. This paper explores the effect of legislation on the treatment practices and role of naturopaths in South Africa. Methods: This was a qualitative study which used an exploratory approach. Participants were sampled from the list of naturopaths registered with the Allied Health Professions Council of South Africa (AHPCSA). A set of 15 openended survey questions were emailed to 59 naturopaths. Twenty one naturopaths participated: 13 responded via email and eight were interviewed. Responses were coded and thematically analysed. Results: It was found that despite differences in training and years of practice experience, four core treatment practices of diet therapy, lifestyle medicine, supplementation and physical therapies were common to all participants with the older, more experienced naturopaths using a wider range of treatment practices

"Big Food", the consumer food environment, health and the policy response in South Africa

Summary Points: * In South Africa, as in other jurisdictions, ‘‘Big Food’’ (large commercial entities that dominate the food and beverage environment) is becoming more widespread and is implicated in unhealthy eating. * ‘‘Small food’’ remains significant in the food environment in South Africa, and it is both linked with, and threatened by, Big Food. * Big Food in South Africa involves South African companies, some of which have invested in other (mainly, but not only, African) nations, as well as companies headquartered in North America and Europe. * These companies have developed strategies to increase the availability, affordability, and acceptability of their foods in South Africa; they have also developed a range of ‘‘health and wellness’’ initiatives. Whether these initiatives have had a net positive or net negative impact is not clear. The South African government should act urgently to mitigate the adverse health effects in the food environment in South Africa through education about the health risks of unhealthy diets, regulation of Big Food, and support for healthy foods.Web of Scienc
