Child obesity prevention is a relatively new phenomenon in developing countries where food insecurity and malnutrition have been the public health focus. Yet obesity is a global health problem. The purpose of this study was to compare healthy and unhealthy food choices among a convenience sample of 114 adolescent youths from ethically and economically diverse communities in Cape Town, South Africa and New York City using surveys and focus groups. Findings showed no significant differences in healthy food choices among participants regardless of socioeconomic status (SES). For unhealthy food choices, there were significant differences between adolescents from low and middle SES levels. Interviews indicated that unhealthy choices were influenced by money, convenience, and parents. School feeding programs were influential in initiating and sustaining healthy choices, whereas barriers included money and convenience of access to unhealthy food options. Parents and schools provided the most influence on these adolescents’ healthy options by including fruits and vegetables in homemade and school program lunches.

AbstractObjectives:To determine vitamin A intake of children aged 2–5 years in a rural South African community one year after the implementation of a home-based food production programme targeting β-carotene-rich fruits and vegetables.Design:Dietary intake of children aged 2–5 years was determined during a cross-sectional survey before and one year after the implementation of a home-based food production programme.Setting:A low socio-economic rural African community, approximately 60 km north-west of the coastal city of Durban in kwaZulu-Natal, South Africa.Subjects:Children aged 2–5 years (n=100); 50 children from households with home-gardens producing β-carotene fruits and vegetables (project gardens), and 50 children from households without project gardens.Results:As compared with baseline data, there was a significant increase in vitamin A intake in children from households with project gardens as well as in children from households without project gardens. However, children from households with project gardens had a significantly higher vitamin A intake than children from households without project gardens. The increased vitamin A intake in those children from households without project gardens can be attributed to the availability of butternuts in the local shop (as a result of the project), and because the mothers negotiated with project garden mothers to obtain these fruits and vegetables for their children.Conclusion:A home-based food production programme targeting β-carotene-rich fruits and vegetables can lead to an increase in vitamin A intake.

Food Purchases

Abstract Objective: To identify factors associated with food purchasing decisions and expenditure of South African supermarket shoppers across income levels. Design: Intercept surveys were conducted, grocery receipts collated and expenditure coded into categories, with each category calculated as percentage of the total expenditure. In-supermarket food quality audit and shelf space measurements of foods such as fruits and vegetables (F&V) (healthy foods), snacks and sugar-sweetened beverages (SSB) (unhealthy foods) were also assessed. Shoppers and supermarkets were classified by high-, middle- and low-income socio-economic areas (SEA) of residential area and location, respectively. Shoppers were also classified as “out-shoppers” (persons shopping outside their residential SEA) and “in-shoppers” (persons shopping in their residential SEA). Data were analysed using descriptive analysis and ANOVA. Setting: Supermarkets located in different SEA in urban Cape Town. Participants: Three hundred ninety-five shoppers from eleven purposively selected supermarkets. Results: Shelf space ratio of total healthy foods v. unhealthy foods in all the supermarkets was low, with supermarkets located in high SEA having the lowest ratio but better quality of fresh F&V. The share expenditure on SSB and snacks was higher than F&V in all SEA. Food secure shoppers spent more on food, but food items purchased frequently did not differ from the food insecure shoppers. Socio-economic status and food security were associated with greater expenditure on food items in supermarkets but not with overall healthier food purchases. Conclusion: Urban supermarket shoppers in South Africa spent substantially more on unhealthy food items, which were also allocated greater shelf space, compared with healthier foods.

Maximum Residue Levels

ABSTRACT Six years of pesticide residue data from fresh produce destined for the export market were analyzed for the period 2009 to 2014. A total of 37,838 fruit (99.27%) and vegetable (0.73%) data sets analyzed for the presence of 73 pesticides were compared. Pesticides were detected on 56.46% of samples, of which 0.78% had multiple residues. Noncompliances detected were because of the use of unregistered pesticides (0.73%), values that exceeded established maximum residue levels (MRLs) (0.32%), or the combination of values that exceeded MRLs and the use of unregistered pesticide residues (0.003%). The most commonly detected pesticides that exceeded established MRLs were imazalil (37.71%), prochloraz (28.69%), and iprodione (5.74%). The unregistered pesticide most often found on grapes and avocados was also imazalil (62.23%) and, on nectarines and avocados, diphenylamine (11.15%). Exceedances of MRL values were mostly associated with oranges (43.44%), avocados (27.87%), grapefruits (7.38%), and lemons (6.56%). Residual pesticide monitoring on fruits and vegetables is a key tool to ensure conformity with regulatory requirements and compliance with good agricultural practices and the trade requirements set by the importing country.

Nudaurelia capensis β virus (NβV) is an RNA virus of the South African Pine Emperor moth, Nudaurelia cytherea capensis (Lepidoptera: Saturniidae). The NβV capsid is a T = 4 icosahedron that contains 60T = 240 subunits of the coat protein (Mr = 61,000). A three-dimensional reconstruction of the NβV capsid was previously computed from visions embedded in negative stain suspended over holes in a carbon film. We have re-examined the three-dimensional structure of NβV, using cryo-microscopy to examine the native, unstained structure of the virion and to provide a initial phasing model for high-resolution x-ray crystallographic studiesNβV was purified and prepared for cryo-microscopy as described. Micrographs were recorded ∼1 - 2 μm underfocus at a magnification of 49,000X with a total electron dose of about 1800 e-/nm2.
