In Western countries two common and successful measures employed to combat nutritional deficiencies and deficiency diseases are: (i) enrichment of refined cereal products with nutrients lost during milling; and (ii) fortification of common foodstuffs with nutrients the intake of which in the general population is regarded as inadequate. In South Africa in 1978 a committee appointed by the Medical Research Council urged that because of the nutritional situation, particularly among the Black population and more especially relating to pellagra, niacin, riboflavin and folic acid should be added to the staple maize meal. Accordingly, investigations have been undertaken to assess the ability of Blacks to discriminate between fortified and non-fortified maize meals. Studies on groups of adolescents and adults revealed that this ability is not significant, indicating that no problem should be encountered as regards the general acceptability of the fortified product. These findings are in agreement with acceptance by the public overseas of enriched bread and 'corn' products where the latter have been introduced. There is therefore no reason why the milling industry should delay the fortification of all maize meal produced for human consumption.
