Objective: To review studies examining the nutritional value of street foods and their contribution to the diet of consumers in developing countries. Design: The electronic databases PubMed/MEDLINE, Web of Science, Cochrane Library, Proquest Health and Science Direct were searched for articles on street foods in developing countries that included findings on nutritional value. Results: From a total of 639 articles, twenty-three studies were retained since they met the inclusion criteria. In summary, daily energy intake from street foods in adults ranged from 13 % to 50 % of energy and in children from 13 % to 40 % of energy. Although the amounts differed from place to place, even at the lowest values of the percentage of energy intake range, energy from street foods made a significant contribution to the diet. Furthermore, the majority of studies suggest that street foods contributed significantly to the daily intake of protein, often at 50 % of the RDA. The data on fat and carbohydrate intakes are of some concern because of the assumed high contribution of street foods to the total intakes of fat, trans-fat, salt and sugar in numerous studies and their possible role in the development of obesity and non-communicable diseases. Few studies have provided data on the intake of micronutrients, but these tended to be high for Fe and vitamin A while low for Ca and thiamin. Conclusions: Street foods make a significant contribution to energy and protein intakes of people in developing countries and their use should be encouraged if they are healthy traditional foods.

This study investigated how far the post-apartheid government has progressed in creating a better life for all South Africans. Secondary data analysis was employed using the 2008 South African Social Attitudes Survey (SASAS) of 3321 randomly selected adult respondents. A series of general linear models examined the impact of race, gender, age, geographic location, education level, living standard measure (LSM), satisfaction with basic services, and fear of crime on quality of life (QOL) as measured respectively by subjective well-being indicators, namely happiness, life-satisfaction and optimism. 1 The main findings were that: 1) Those respondents who feared crime less, had higher LSM levels, and were satisfied with basic services reported higher levels of happiness. 2) Those respondents who had a higher LSM, feared crime less, and were more satisfied with the basic services reported higher lifesatisfaction. 3) Those respondents who were black African with lower levels of education, feared crime less, and were most satisfied with basic services displayed the most optimism about the future. We concluded that government interventions need to focus more on black Africans, the least educated, the low LSM group, those living in the urban informal areas, and those who fear crime to significantly improve South Africans' QOL.
