There is direct correlation between consumption of plant foods and occurrence of chronic degenerative diseases, one of such plants is Musa species. In this research work, five varieties of banana commonly consumed in Nigeria were evaluated for proximate, mineral compositions and antioxidant capacities using standard analytical techniques. Results revealed that varieties of banana namely; baby/nino, burro, red, monzano and cavendish were low in crude protein, fat and fibre but, they were significantly high in K, Mg and P. Also, the carbohydrates and dietary energy were of high values. Antioxidant activity (AA) and Total phenolic content (TPC) of the aqueous extracts of the samples ranged from 0.67-4.84 and 1.21-2.55 mg/100g respectively. This indicates that the five varieties commonly consumed by adults and children as food and food adjuncts can possibly be utilized as sources of vital minerals and possible scavengers of free radicals thereby preventing the symptoms that are associated with degenerative diseases.
