The vegetable consumption pattern of households in selected areas in the old Rivers State (now Rivers and Bayelsa States) in Nigeria was investigated. Areas studied were Port Harcourt the State capital, Igwuruta, Ahoada and Kaiama. Results showed that mothers consumed 59 ± 0.45g to 130 ± 2.04g/person/day of vegetables between the months of May and July, the peak season of vegetable production. Factors that influenced vegetable consumption were found to be chiefly season and culture. Other factors were availability/price for 43.8% of households in Kaiama, a riverine community, while taste and nutrition knowledge wielded minor influences. Leafy vegetables were consumed at least four times per week in Igwuruta and Port Harcourt, while households in Ahoada and Kaiama, where culture had strong influence, consumed them only occasionally. Vegetables consumed were mainly pumpkin leaves (Telfairia occidentialis) and okro (Abelmoschus esculentus) in areas where season played a strong role. In areas where culture had a strong influence, bitterleaf, a leafy vegetable that undergoes rigorous process of squeezing and washing and is only scantly used in soups, was the vegetable of choice. Other vegetables less frequently consumed were Amaranthus hybridus, Pterocarpus spp., Gnetum africanum and Piper guineense leaves. These were used chiefly in various soup dishes eaten as accompaniments with the starchy staples. Other dishes in which leafy vegetables were consumed were pottage in those areas of high vegetable consumption, and occasionally in stew by all households investigated. Household size of 5 to 8 persons consumed their soup dishes between two and four days, while larger households of nine and above ate their soups in one day. However, households with deep freezer facilities stored their soup dishes for up to seven days. In spite of the reasonable consumption of vegetables during the peak season of production, reports of micronutrient deficiencies in Nigeria are rife, indicating a need for intervention. Possible reasons for the high prevalence of micronutrient deficiencies are seasonal variations in vegetable production, inadequate processing and preservation of vegetables for all year distribution and culture which may limit adequate consumption of leafy vegetables even when they are in abundance. This situation underscores the need for nutrition education, coupled with a program on dietary diversification to create awareness, increase production, processing, preservation and consumption of vegetables.
