Influence of fiber on postprandial intragastric juice acidity, pepsin, and bile acids in healthy subjects.
The effect of a fiber-enriched wheat bran product, Fiberform, and a guar gum preparation, Guarem, on postprandial intragastric juice acidity and pepsin and bile acid concentrations was studied in healthy subjects. Fiber-enriched wheat bran prolonged significantly the meal-induced elevation of pH and decrease in pepsin. Both fiber products reduced postprandial intragastric bile acid concentration.
