Protein and vitamin B6 content of foods consumed by Nigerian adolescents
1991
Ajayi, O.A. | Korede, O.
The moisture, protein and vitamin B6 contents of foods commonly consumed in Nigeria were determined. Subsequently, dietary protein and vitamin B6 consumption of 41 adolescents resident in a post primary Institution were assessed over a 7-day period. The vitamin B6 content of the foods as estimated by chemical method correlated strongly (r = 0.8562, P < 0.001) with values obtained from microbiological assay (using Saccharomyces uvarum as test organism). Likewise, a strong and positive correlation existed between protein and vitamin B6 content as determined by chemical assay (r = 0.3927, P < 0.02) or by microbiological assay (r = 0.7161, P < 0.002). Vitamin B6 intake of the adolescents also correlated significantly (r = 0.8741, P < 0.001) with protein intake. The daily mean vitamin B6 and protein intake was 1.5 +/- 0.34 mg and 62.1 +/- 13.1 g, respectively. The findings indicate that population groups that consume staple diets based on roots and tubers or those who do not meet their needs for protein would have poor vitamin B6 status. Since institutional diets are often better than diets consumed in many homes, an extensive study of vitamin B6 consumption patterns of other population groups is suggested.
