Diversity and immune boosting claims of some African indigenous leafy vegetables in western Kenya
A survey was carried out to document the diversity and immune boosting claims of African indigenous leafy vegetables (AILVs) in Western Kenya. Both qualitative and quantitative methods of data collection were used. The results showed that there is diversity of AILVs in the study area with nine popular and frequently consumed, but cassava leaves, stinging nettle and russian comfry are not popular. Seven of these are cultivated but two, stinging nettle (Urtica massaica) and vine spinach (Basella alba) grow wildly. The AILVs are cultivated at subsistence level on home gardens withminimal inputs and only excess of this is sold. The religion one belonged to was significant (p<0.05) in determining consumption or not of some of the vegetables. The vegetables are rain fed and the process of harvesting is by first uprooting during thinning followed by breaking the main stem and finally plucking off the leaves with maturity. Vegetable preparation in most households was mainly by women. The elderly women were keen in this process and spent more time in preparing the vegetables which were believed to be ânutritiousâ. There was no processing and preservation of the AILVs for use during the dry season. The communities rely on wild weeds during such seasons. The AILVs though consumed for good nutrition are also associated with various medicinal and immune boosting claims. Out of the nine, five are known for various health benefits, African nightshade and spider plant for good nutrition by 31.8% and 25.1% of the respondents, respectively, slender leaf for healing power by 34%, cowpea leaves and slender leaf for anti-aging by 50% and 43.8%, respectively, and cowpea leaves (43.6%) and amaranthus (53%) for smooth skin and adding blood, respectively. Chi square analysis indicated that African nightshade, spider plant and amaranthus are statistically significant (p<0.05) incontributing to good nutrition, healthy functioning of the body and immune boosting. Further analysis showed that spider plant and amaranthus are significant (p<0.05) for immune boosting.Key words: indigenous vegetables, diversity, immune boostin

Nutritional characterisation of low-income households of Nairobi: socioeconomic, livestock and gender considerations and predictors of malnutrition from a cross-sectional survey
Background:
In sub-Saharan Africa, urban informal settlements are rapidly expanding, leading to overcrowding and constituting challenging environments for food and water supplies, health and nutrition. The study objectives were to characterise and compare two low-income areas of Nairobi according to socioeconomic (including livestock and gender) indicators and the nutritional status of non-pregnant women of reproductive age and 1 to 3 year-old children; and to investigate socioeconomic predictors of malnutrition in these areas.
Methods:
In this cross-sectional survey 205 low-income households in deprived areas of Dagoretti and Korogocho (Nairobi) were randomly selected. Socioeconomic data were collected via an interviewer-administered questionnaire. Maternal and child dietary data were collected by a 24-h dietary recall. Maternal and child anthropometric and haemoglobin measurements were taken. Chi-square, t-test and Wilcoxon-MannâWhitney test were used to compare groups and multivariable linear regression to assess predictors of malnutrition.
Results:
Dagoretti consistently showed better socioeconomic indicators including: income, education and occupation of household head, land ownership, housing quality and domestic asset ownership. Animal ownership was more than twice as high in Dagoretti as in Korogocho (53.0 % vs 22.9 % of households; p-valueâ<â0.0001). A double burden of malnutrition existed: 41.5 % of children were stunted, and 29.0 % of women were overweight. In addition, 74.0 % of the children and 25.9 % of the women were anaemic, and were at risk of inadequate intakes for a number of micronutrients. Nutritional status and nutrient intakes were consistently better in Dagoretti than Korogocho; height-for-age (0.47 Z-scores higher; p-valueâ=â0.004), the minimum dietary diversity (80.0 % vs 57.7 % in children, p-valueâ=â0.001) and intakes of several nutrients were significantly higher. Positive predictors of maternal nutritional status were income, age and not having a premature delivery. Positive predictors of child nutritional status were area, household head education, mother not being married, female animal ownership and childâs sex (female).
Conclusions:
Malnutrition is prevalent in these settings, which could be partly due to low nutrient intakes, and to socioeconomic factors (including poverty), thus requiring comprehensive approaches that include increased accessibility and affordability of nutrient-dense foods. This study indicates that differences among low-income areas may need consideration for prioritisation and design of interventions
Diversity And Immune Boosting Claims Of Some African Indigenous Leafy Vegetables In Western Kenya
A survey was carried out to document the diversity and immune boosting
claims of African indigenous leafy vegetables (AILVs) in Western Kenya.
Both qualitative and quantitative methods of data collection were used.
The results showed that there is diversity of AILVs in the study area
with nine popular and frequently consumed, but cassava leaves, stinging
nettle and russian comfry are not popular. Seven of these are
cultivated but two, stinging nettle ( Urtica massaica ) and vine
spinach ( Basella alba ) grow wildly. The AILVs are cultivated at
subsistence level on home gardens with minimal inputs and only excess
of this is sold. The religion one belonged to was significant
(p<0.05) in determining consumption or not of some of the
vegetables. The vegetables are rain fed and the process of harvesting
is by first uprooting during thinning followed by breaking the main
stem and finally plucking off the leaves with maturity. Vegetable
preparation in most households was mainly by women. The elderly women
were keen in this process and spent more time in preparing the
vegetables which were believed to be ânutritiousâ. There
was no processing and preservation of the AILVs for use during the dry
season. The communities rely on wild weeds during such seasons. The
AILVs though consumed for good nutrition are also associated with
various medicinal and immune boosting claims. Out of the nine, five are
known for various health benefits, African nightshade and spider plant
for good nutrition by 31.8% and 25.1% of the respondents, respectively,
slender leaf for healing power by 34%, cowpea leaves and slender leaf
for anti-aging by 50% and 43.8%, respectively, and cowpea leaves
(43.6%) and amaranthus (53%) for smooth skin and adding blood,
respectively. Chi square analysis indicated that African night shade,
spider plant and amaranthus are statistically significant (p<0.05)
in contributing to good nutrition, healthy functioning of the body and
immune boosting. Further analysis showed that spider plant and
amaranthus are significant (p<0.05) for immune boosting
