This situation is attributed to shift in cultivation towards cereals, crop production in areas with low nutrient availability and consumption of food crops with inherently low nutrient concentrations. Cereals are inherently low in micronutrients, compared to many other food crops and their consumption as staple food leads to micronutrient deficiencies. The deficiencies are exacerbated by a lack of animal products or fish in the diet (Gibson 2006). The deficiency of a nutrient can cause impairment of some specific biochemical function and illnesses in human being
