Effects of Sweet Potato on Gastric Acid Secretion in Rats

Abstract: In order to explore the reasons for the symptoms like heartburn and reflux caused by eating sweet potatoes ,the gastric acid secretion and gastric environment situation of SD rats after fed sweet pota-toes have been studied in this paper ,based on the measuring the pH of gastric juice and duodenal juice and the gastric acid output .The results show that the sweet potato powder content in the feed is negatively correlated to both the gastric juice pH and the gastric acid output ,1 h after SD rats are fed(p<0 .01);and the buffering performance of basic feed is significantly stronger than sweet potato’s(p<0 .01) .Since the buffer effect of sweet potato feed is relatively weak ,the gastric juice pH does not increase significantly as much as the basic feed and is maintained at a lower level ,which results in little increase of gastric acid out-put .Besides ,the lower gastric juice pH leads to heartburn ,reflux and other symptoms .
