In Kenya, beetroot bulbs are occasionally used as a blend in fruit juices and salads, as a livestock feed and for treatment of diseases. Analysis of essential elements in beetroot bulbs was performed using Energy Dispersive X-ray fluorescence (EDXRF) in order to determine the nutritional content of the bulbs. The beetroot bulbs were sampled from five different geographical regions in Kenya; Karatina, Gilgil, Naivasha, Joska and Kisumu. The results of the concentrations of the essential elements had a range of: 10000 mg kg-1 to 61000 mg kg-1 for potassium, 500 mg kg-1 to 4500 mg kg-1 for calcium, 15.0 mg kg-1 to 230 mg kg-1 for manganese, 24.0 mg kg-1 to 770 mg kg-1 for iron and 16.0 mg kg-1 to 680 mg kg-1 for zinc. In general, the trend in the concentrations of the essential elements was K > Ca > Fe > Mn > Zn. Karatina samples registered the highest concentrations for all the elements of interest in this study. The results of analysis of variance (ANOVA) for all the five sampled regions show that there is a significant difference in the Ca, Fe and Mn concentration levels. Beetroots were found to contain sufficient amounts of the essential elements, therefore, are a suitable vegetable source of essential elements of K, Ca, Mn, Fe and Zn and can be used as an immune system booster. This study is supportive to the Government’s efforts of improving health care and in the fight against “hidden hunger-malnutrition” in the country.
