The combination of poverty-related infectious and lifestyle-related non-communicable diseases, both driven by malnutrition, causes a high burden for South Africa. Healthy and nutritious diets for populations depend on availability and accessibility of a variety of plant and animal foods, within a context that promotes and supports healthy behaviour. Food based strategies, such as supplementation, food fortification, and diversification of crops, are used to achieve optimal dietary requirements to combat malnutrition, including micronutrient deficiencies. A more sustainable food based strategy is the (promotion of) use of indigenous and traditional foods, such as African Leafy Vegetables (ALVs). Unfortunately, several studies from all over Africa have shown that there is a shift from traditional diets as result of the preparing techniques and the absence of women in homes. Furthermore, indigenous and traditional foods are considered as "poor people's food".
Against this background, a joint project between South Africa, Kenya and Benin is designed to fill the gaps in knowledge in these countries regarding the availability, acceptability and consumption and evidenced based benefits of foods from local biodiversity. The main aim of the study in South Africa is to provide empirical evidence of how the role of biodiversity can be translated into improved health status in contemporary poor rural and urban communities in the North West Province of South Africa. In order to achieve this it is important to gain knowledge on the possibility of using ALVs as a strategy to alleviate micronutrient deficiencies. Therefore an intervention study to determine the effect of selected ALV on the nutritional status (including zinc, iron, and vitamin A status) of school children (grade R-4) residing in contemporary poor rural community in the North West Province, South Africa has been designed.

|Official Title:||The Effect of African Leafy Vegetables on Nutritional Status (Including Iron, Zinc and Vitamin A Status) of School Children Residing in Semi-rural Farm Community in the North West Province of South Africa|
|Study Start Date :||February 2012|
|Actual Primary Completion Date :||May 2012|
|Actual Study Completion Date :||June 2012|
300 gram cooked African leafy vegetables and school meal starch as daily school meal (5 days/weeks) for 3 months.
Selected African leafy vegetables:Amaranthus cruentus (amaranth), Vigna unguiculata (cowpea), Cleome gynandra (spiderplant), and Cucurbita maxima (pumpkin).
Random allocation of children of two rural farm schools per grade to receive either 300 gram cooked ALVs and school meal starch or the normal school meal as daily meal (5 days/weeks) for 3 months.
No Intervention: Control
normal school meal as daily meal (5 days/weeks) for 3 months
- Change in nutritional status of school children (nutritional status measured by: blood haemoglobin, serum ferritin, serum zinc and serum retinol) [ Time Frame: three months ]
- Change in nutritional status of school children (nutritional status measured by: height-for-age z-score, weight-for-age z-score and BMI-for-age z-score) [ Time Frame: three months ]
