Abstract:
and poor health among consumers in Sub-Saharan Africa cannot be overemphasized. This is due
to high contents of vitamins, essential minerals and a source of dietary fiber. Although TAVs form
a significant component of many families` diets in Tanzania, consumption is still below the amount
recommend by WHO and FAO in most regions. This study identified traditional African
vegetables with high nutritional potential and examined awareness of nutrition knowledge, factors
that influence intake frequency of traditional African vegetables and attitudes of farmers, traders
and consumers towards traditional vegetables. The study used data collected from 381 respondents
through personal interviews using pre-tested questionnaires and focus group discussion. The study
was conducted in Arumeru District, Arusha Region. The analysis was conducted using regression
models. Generalized Poisson regression model was used to determine awareness of nutrition
knowledge and factors influencing intake frequency of traditional African vegetables among
farmers, traders and consumers. Descriptive and factor analysis methods were used to assess the
attitudes of farmers, traders and consumers towards traditional African vegetables.
Descriptive statistics results showed that African nightshade was ranked high due to its nutritional
potential based on the opinion of the respondents. The study found out that there was average
awareness of nutrition knowledge for both farmers, traders and consumers. Results indicate that
awareness of nutrition knowledge was highest in the famers category. Generalized Poisson
regression results show that gender, number of years in schooling, age household size and farm
size influence farmers’ awareness of nutrition knowledge. The results also show that age, number
of years in schooling, annual income, household size, interaction of age and annual income, and
interaction of number of years in schooling and annual income influence traders’ awareness of
v
nutrition knowledge whereas consumers’ awareness of nutrition knowledge was influenced by age,
numbers of years in schooling and occupation of the respondent. Also, generalized Poisson
regression results show that age, annual income, household size, TAVs farm size and price of
TAVs influence famers’ intake frequency of traditional African Vegetables. Gender and medicinal
properties influence traders’ intake frequency whereas distance to the market, culture/ taboos, price
of TAVs and TAVs weekly budget influence consumers’ intake frequency of traditional African
vegetables. Lastly, the results of the descriptive and factor analysis indicate that farmers’ attitude
towards consumption of traditional African vegetables was associated with health benefits,
personal perception and taste. Traders’ attitude towards consumption of traditional African
vegetables was associated with health benefits, taste, time factor and personal perception whereas
taste, health benefits, freshness and perception were associated with consumers’ attitude. The
implication of the findings is that consumption of traditional African vegetables can be enhanced
The contribution of Traditional African Vegetables (TAVs) to reduction of malnutrition, stunting by; (i) creating awareness of the benefits of consuming traditional vegetables using easy to
understand approaches such as: (ii) educational materials on vegetable in schools and, campaigns
and road show; (iii) development, documentation and promotion of recipes and cooking
demonstrations.
