Nutritional value of wild, leafy plants consumed by the Vhavenda : research letter
2001
We investigated the use and nutrient composition of edible wild
plants commonly used in Venda. Information on their eating habits
was sought from 412 women in the districts of Thohoyandou,
Mutale, Dzanani and Vuwani, who were regular consumers of wild,
green, leafy vegetables. The ten most commonly used vegetables
were identified through a 'grid matrix' test among sixteen randomly
selected hawkers selling wild plants in Thohoyandou markets in
1996. The ten plants studied were: delelele mandande, thebe, vowa,
mushidzhi, murudi, mutohotoho, delele lupfumo, phuri, nngu, l/Ig and muxe . Data on plant usage was obtained by means of a questionnaire.
Nutritional analysis of the vegetables investigated was conducted
by the CSIR. Harvesting was mainly in summer with the
surplus stored in either a dried-cooked or dried-raw form for at least
six months. Frequency of consumption was once per week per plant
with fairly large serving sizes of 180-270 g. lIgMurudil/Ig was found to
have the highest content of micronutrients, being exceptionally
high in folate (418 µg/100 g), vitamin C (37.0 mg/100 g) and betacarotene
(9.22 mg/100 g). All the plants examined were good
sources of dietary fibre. Vowa, phuril/Ig and lIgnngul/Ig were also rich
sources of vitamin C. Delele mandandel/Ig was the only poor source of
beta-carotene and iron. Health educators should promote the nutritional
benefits of wild vegetables in rural communities in order to
increase micronutrient intake.
