Item 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, ErnestaThe 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.Item 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, NeliaStreet 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.Item 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, ErnestaIn 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.Item Nutrient density and cost of commonly consumed foods: A South African perspective(Cambridge University Press, 2022) Madlala, Samukelisiwe S; Hill, Jillian; Kunneke, Ernesta; Faber, MiekeFood-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.
