The effect of acidic substances included in food on the bioavailability of dietary zinc was studied in rat. Wister strain male albino rats were ad libitum fed one of six semipurified test diets supplemented with or without 1% of acidic substance for 31 days. Body weight gain and food consumption in the rat group fed diet contained phytic acid were apparently lower than the control group in which rats were fed diet not containing any acidic substance. In rats fed diets containing acidic substances othar than phytic acid, body weight gain and food consumption were about equivalent with the control. The apparent digestibility of dietary zinc in rats fed diets containing citric acid or ascorbic acid was significantly higher than the control group. Zinc content in tbia or femur of rats fed diet ascorbic acid containing diet was significantly higher than the control. Overall, acidic substances examined except phytic acid did not inhibit the bioavailabibty of dietary zinc.
