Influence of variety of Nigerian rice on experimental peptic ulceration

ABSTRACT

The susceptibility of rats prefed with five varieties of rice to indomethacin - induced gastric ulceration was studied. The degree of ulceration was significantly higher (P0.001) in rats fed with white polished rice than in any of the two local rice varieties (Tapa and Ofada). Ulceration was significantly lower (P 0.001) in the brown rice-fed rats than with the polished rice-fed rats. This study indicates that the modern milling processes which improve the palatability and digestibility of rice remove most of the required vitamins along with the bran. Lack of these vitamins makes animals susceptible to gastric ulceration
