A public health strategy for increasing the potassium and magnesium intake of the population was explored. These electrolytes have been confirmed by epidemiological studies to have some health benefits. A process for production of mineral water using palm bunch ash was developed. The composition of the palm bunch ash derived from oil palm Elaeis guineensis was determined and it was(PBA) found to contain potassium and magnesium in significant amounts. The ash solution was used to produce mineral water that has ionic composition comparable to those of some brands of bottled mineral water. The mineral water so produced had potassium and magnesium contents of up to 17.5mg/l and 0.5mg /l respectively, representing at least 0.15% and 0.1% of the recommended dietary allowance (RDA). This palm bunch ash mineral water is unique in that it contains both essential minerals and some trace elements required for good health, and might be a better substitute for patients with hypokalemia in view of its alkalinity and phosphate content.
