    Adult food choices in association with the local retail food environment and food access in resource-poor communities: A scoping review protocol
    (BMJ Publishing Group, 2021) Madlala, Samukelisiwe Sthokozisiwe; Hill, Jillian; Kunneke, Ernesta
    The local retail food environment influences dietary patterns and food choices, as suggested in the literature. The lack of access to healthy food within this environment may result in unhealthy food choices which may lead to obesity and the development of noncommunicable diseases. Evidence suggests that resourcepoor communities may have unhealthy food environments, therefore, preventing residents from making healthy food choices. A systematic scoping review will be conducted to provide an overview of the evidence on adult food choices in association with the local retail food environment and food access in resource-poor communities.

    Consumption patterns of street food consumers in Cape Town
    (South African Association of Family Ecology and Consumer Sciences (SAAFECS)., 2016) Hill, Jillian; Mchiza, Zandile; Fourie, Jean; Puoane, Thandi; Steyn, Nelia
    Street foods (SF) contribute significantly to the diet of people living in low- and middle-income countries, however there is a paucity of data on consumption patterns of SF. Since many South Africans consume SF regularly, it is important to determine their purchasing habits, food choices, and nutrition knowledge. A cross-sectional survey conducted in Cape Town metropolitan area, with trained fieldworkers using a structured questionnaire on 1121 SF consumers. The first ten clients who visited a randomly-sampled SF vendor were approached and invited to participate. Data were analysed using IBM Statistics SPSS version 23. Most consumers were black, male, single, and had some high-school education and/or matriculated. Main findings indicated that 38% of these consumers consumed SF almost daily, 43.3% consumed SF frequently (2-3 times per week) and 29% spent between R600 and R899 per month on SF. Items purchased most often in descending order of frequency were fruit, foods and baked products, cold drinks, sweets, peanuts, crisps, fruit juice, biscuits, and chocolates. If healthier SF were available, 96% consumers indicated they would purchase these, with fruit, meat/chicken and vegetable stew, yoghurt and nuts being preferred options. There is a large market for SF consumers in Cape Town. However, most food items consumed, with the exception of fruit and peanuts, are unhealthy by virtue of their high sugar and fat content. SF consumers are however, willing to purchase healthier foods, should these be available.

    The development of a street-food vending model that offers healthy foods for sale
    (University of the Western Cape, 2016) Hill, Jillian; Puoane, Thandi; Mchiza, Zandile; Steyn, Nelia
    Background: Street foods (SF) contribute significantly to the nutritional intake of adults and children in developing countries. They are inexpensive and a major source of income for a vast multitude. A major concern is the so-called ‘nutrition transition’, which has led to an increase in foods high in saturated fats, trans fats, sugar and salt, along with processed food items sold on urban community streets in developing countries. These foods contribute to nutritional disorders in the communities where consumed. South Africa’s stable unemployment rate, estimated at 25%, has further influenced business growth in the informal sector, particularly SF vending. As such, a well-developed SF-vending model (SFVM) could potentially address the challenges of unemployment and improve the nutritional status of poorer South Africans. Aim: To develop a sustainable SFVM for selling healthy and safe SF in the City of Cape Town enabling street vendors to make a decent living, and consumers to make healthy choices regarding food purchasing. Methods: This cross-sectional study employed mixed methodology (collecting qualitative and quantitative data). The study was conducted in three phases. Phase 1a: Situation Analysis. This a SF-vendor survey which collected a) socio-demographic factors, b) vendors’ business operational models, c) food items sold, d) available facilities, e) challenges faced, f) certification, and g) nutrition knowledge using a validated questionnaire. An observational checklist capturing data on the appearance of vendors, their stalls, available equipment and type of food sold, supplemented this survey. Phase 1b: A consumer survey included collecting, a) socio-demographic factors, b) purchasing habits, c) consumption preferences, and d) nutrition knowledge using a validated questionnaire. Phase 2a: Semi-structured-interviews and focus group discussions with Environmental Health Officials and Economic Development Officials from the City of Cape Town were conducted to explore the existing -vending regulations and/or policies in the City of Cape Town and gain insight into the SF-vending operations from a regulatory perspective. Phase 2b: A document review was conducted to identify existing regulations and policies on SF vending. Phase 3: conducted in three steps: Step 1, data integration of the previous phases. Step 2, a participatory action research component checking the relevance, acceptability and practicability of identified themes and resulting components from Step 1. Step 3, development of the proposed SFVM using the findings of the previous two steps. Data Analysis: Quantitative data were analysed using IBM SPSS, 2010 Statistics version 23. Descriptive statistics and cross-tabulations were used to analyse data. Qualitative data were thematically analysed using the qualitative data software package Atlas ti 7.5.7.Results: Phase 1a: vendors in the Cape Town and surrounding areas work long hours up to seven days a week making a minimal income. Types of food items sold by vendors, their nutrition knowledge and hygiene practices were not ideal. A major lack in basic facilities existed. Phase 2a: SF consumers indicated spending a significant amount of their income on SF, and are open to buying healthier options should these be available. Phase 2a: government officials thought the SF-vending business should be guided by national legislature and provincial bylaws, and felt strongly about nutrition and health education for vendors and consumers. Phase 2b: thirteen regulations and bylaws applicable to SF vending were sourced. Phase 3: Data from the previous phases were integrated within a socio-ecological framework to develop the proposed SFVM. The components of this model are divided into four areas, i.e. a business component, food and nutrition component, hygiene component, and a vending cart. Conclusion: The four components in the proposed SFVM take into account various elements of the socio-ecological framework, i.e. intrapersonal/individual, interpersonal, the physical environment/community and the policy environment. This SFVM should be piloted, evaluated, adapted and before rolling it out on a large scale to test its effectiveness.

    Dietary diversity and its association with nutritional status, cardiometabolic risk factors and food choices of adults at risk for type 2 diabetes mellitus in Cape Town, South Africa
    (MDPI, 2022) Madlala, Samukelisiwe S.; Hill, Jillian; Kunneke, Ernesta
    In South Africa, the nutrition transition has led to unhealthy diets lacking variety, contributing to the rise in overweight, obesity and diet-related noncommunicable diseases. Using baseline screening data of the South African Diabetes Prevention Programme (SA-DPP) study, this study aims to determine the relationship of dietary diversity (DD) with nutritional status, cardiometabolic risk factors and food choices of adults at risk of type 2 diabetes in resource-poor communities around Cape Town. Data of 693 adults, 25–65 years old were analysed. This included socio-demographic information, anthropometric measurements, biochemical assessments, food groups consumed the previous day and consumption frequency of certain foods to reflect food choices.

    Nutrient density and cost of commonly consumed foods: A South African perspective
    (Cambridge University Press, 2022) Madlala, Samukelisiwe S; Hill, Jillian; Kunneke, Ernesta; Faber, Mieke
    Food-based dietary guidelines promote consumption of a variety of nutritious foods for optimal health and prevention of chronic disease. However, adherence to these guidelines is challenging because of high food costs. The present study aimed to determine the nutrient density of foods relative to cost in South Africa, with the aim to identify foods within food groups with the best nutritional value per cost. A checklist of 116 food items was developed to record the type, unit, brand and cost of foods. Food prices were obtained from the websites of three national supermarkets and the average cost per 100 g edible portion was used to calculate cost per 100 kcal (418 kJ) for each food item. Nutrient content of the food items was obtained from the South African Food Composition Tables. Nutrient density was calculated using the Nutrient Rich Food (NRF9.3) Index. Nutrient density relative to cost was calculated as NRF9.3/price per 100 kcal. Vegetables and fruits had the highest NRF9.3 score and cost per 100 kcal. Overall, pulses had the highest nutritional value per cost. Fortified maizemeal porridge and bread had the best nutritional value per cost within the starchy food group. Foods with the least nutritional value per cost were fats, oils, foods high in fat and sugar, and foods and drinks high in sugar. Analysis of nutrient density and cost of foods can be used to develop tools to guide low-income consumers to make healthier food choices by identifying foods with the best nutritional value per cost.
