Levels of vitamins in selected indigenous vegetables in Butula, western Kenya were determined and foods containing high levels of vitamin A and E were used to make food formulation. The bioavailability of these vitamins in food formulation was estimated using algorithm procedure. Determination of β-carotene and α-tocopherol content was done using HPLC procedure. Fresh blanched vegetables contained high levels of β-carotene; 4000 − 9700 µg/100g and α-tocopherol levels; 3000 − 7350 µg/100g. Solar dried vegetables contained β-carotene levels ranging from 572 − 854 µg/g and α-tocopherol levels ranging from 281 to 673 µg/g dry weights. Solar dried vegetables contained significantly lower (P<0.05) amounts of β-carotene and α-tocopherol as compared with fresh vegetables. The mean serum retinol α-tocopherol and β-carotene levels were 0.937, 0.144 and 17.787µmol/l respectively. Bioavailability estimated using algorithm indicated a +2.17 change in serum β-carotene and +7.776 changes in serum α-tocopherol, a positive indication that consumption of indigenous vegetables can meet the recommended dietary allowances of vitamins A (750 µg retinol equivalent/day) and E (8 mg/day). The bioavailable vitamins are capable of boosting the immune system and therefore delay early use of ARV’S.

Abstract The promotion and consumption of indigenous vegetables could help mitigate food insecurity and alleviate malnutrition in developing countries. In this respect, 17 accessions (candidate breeding lines that have not yet officially been released) of five African indigenous vegetables: amaranth (Amaranthus cruentus), nightshade (Solanum scabrum), African eggplant (Solanum aethiopicum), jute mallow (Corchorus olitorius) and okra (Abelmoschus callei), previously selected for their superior agronomic and horticultural traits, were evaluated in Cameroon for minerals (Ca, Mg, K, P, Zn and Fe), proteins, and carotenoids content. Nutrient content differed significantly (P<0.001) between cultivars. Amaranth (especially line AM-NKgn) had the highest Ca, Mg, and Zn content in comparison to other genotypes studied. Nightshade had the highest K and Fe content. The highest K and Fe levels were found in nightshades BG24 and SS52, respectively. Nightshade had the highest level of protein, especially line BFS1. The highest amount of carotenoids was identified in the eggplant variety Oforiwa. The study revealed that these vegetables are important sources of some vital nutrients. Increased production and consumption of these nutrient-rich vegetables will help reduce the nutrition-related disorders in Africa.
