    Background: Agricultural Transformation Action Plan (ATAP) was launched in 2012 by Nigerian Federal Government to make agriculture beneficial to all citizens. The success from the program has placed Nigeria globally as one the highest producers of Root and Tuber Crops (RTC). Despite the large quantity of RTC production in Nigeria, many consumers are neglecting its consumption in preference to wheat (which is largely imported to Nigeria from other countries). Diabetes patients are being discouraged from consuming RTC products leaving them dependent on wheat which has resulted in poor diabetes management in Nigeria. The specific objectives of this thesis are: to analyse the socioeconomic characteristics influencing root and tuber crops consumption in favour of (imported) carbohydrate substitute in Delta State Nigeria, to investigate the outcome of the intervention strategy (education of health value of RTC) on the changes in consumption behaviour of consumers in the study area and also to conduct an economic and financial analysis for root and tuber crops value chains with a view to designing and developing policies that will improve the value chains of these crops in the study area. Descriptive statistical research methods as well as multiple regression analysis were utilized to achieve the research objectives.
    Result on first research objective from analysis of the socioeconomic characteristics influencing the consumption of root and tuber crops in favour of wheat revealed that the age of consumers, their annual income, price of cassava and household size influences the consumptions of RTC in the study area.
    Result on second research objective from the intervention on the consumption behaviour of the respondents showed that before the intervention, the rural settlements consume more of cassava and yam with few consumptions of wheat, the consumption behaviour were still maintained even at post intervention period. In the urban area, consumption was higher for yam and wheat and lower for cassava during pre-intervention but after intervention there was a shift in their consumption behaviour. The consumption of wheat reduced drastically while the consumption of cassava increased but yam consumption remained neutral.
    Result on third research objective from the value chain analysis shows that majority of the chain actors are not aware about the health values of their products, these brings about a lot of misconceptions around their products and around the final consumers. Increased income generation by the value chain actors lies in the development of the chain through expansion of the chain and the shift from the production of traditional food and traditional industrial products into the production of non-food and non-traditional industrial products such as industrial starch, high quality cassava flour, ethanol production.
    In conclusion, it was recommended that there is need for government to provide the basic amenities such as good roads linking rural areas where the main production of RTC take place, provide financial assistance to the value chain actors in form of soft loans to ease their financial constraints and also the need to integrate Nigerian traditional functional foods within local research and innovation system taking account of local needs, food habits and priorities. This will go a long way in bridging the wide gap between rural and urban prevalence and reduce the overall incidence of diabetes mellitus and dyslipidaemia in Nigeria and the world at large.
