Is dietary diversity an indicator of food security or dietary quality? A review of measurement issues and research needs.

Abstract: Dietary diversity is usually measured using a simple count of foods or food groups over a given reference period. Our overview however revealed that studies in developed and developing countries have used a variety of food and food-group classification systems different numbers of foods and food groups and varying reference period lengths (ranging from 1 to 15 days). Research should be conducted to validate and compare indicators based on different methodological approaches. It would also be useful to continue to explore whether indicators based on food groups (a simpler approach) perform as well as those based on single foods in predicting outcomes of interest.

Exploring Poverty Traps and Social Exclusion in South Africa Using Qualitative and Quantitative Data

Abstract: Recent theoretical work hypothesises that a polarised society like South Africa will suffer a legacy of ineffective social capital and blocked pathways of upward mobility that leaves large numbers of people trapped in poverty. To explore these ideas, this paper employs a mix of quantitative and qualitative methods. Novel econometric analysis of asset dynamics over the 1993–98 period identifies a dynamic asset poverty threshold that signals that large numbers of South Africans are indeed trapped without a pathway out of poverty. Qualitative analysis of this period and the period 1998–2001 more deeply examines patterns of mobility, and confirms the continuation of this pattern of limited upward mobility and a low-level poverty trap. In addition, the qualitative data permit a closer look at the specific role played by social relationships. While finding ample evidence of active social capital and networks, these are more helpful for non-poor households. For the poor, social capital at best helps sta...

Traditional Food-Processing and Preparation Practices to Enhance the Bioavailability of Micronutrients in Plant-Based Diets

Abstract: Dietary quality is an important limiting factor to adequate nutrition in many resource-poor settings. One aspect of dietary quality with respect to adequacy of micronutrient intakes is bioavailability. Several traditional household food-processing and preparation methods can be used to enhance the bioavailability of micronutrients in plant-based diets. These include thermal processing, mechanical processing, soaking, fermentation, and germination/malting. These strategies aim to increase the physicochemical accessibility of micronutrients, decrease the content of antinutrients, such as phytate, or increase the content of compounds that improve bioavailability. A combination of strategies is probably required to ensure a positive and significant effect on micronutrient adequacy. A long-term participatory intervention in Malawi that used a range of these strategies plus promotion of the intake of other micronutrient-rich foods, including animal-source foods, resulted in improvements in both hemoglobin and lean body mass and a lower incidence of common infections among intervention compared with control children. The suitability of these strategies and their impact on nutritional status and functional health outcomes need to be more broadly assessed.
