In order to investigate the effect of dietary zinc and phytic acid levels on enzyme activity and lipid metabolism in rats, male Sprague-Dawley rats, weighing approximately 60-74g, were fed different diets which contained 0, 0.35 or 1.05% phytic acid each at 3 levels of zinc (0, 30 and 1500ppm zinc) for 28 days. Body weigllt gain, food consumption, and food efficiency ratio were lower in the rats fed a zinc deficient diet (Oppm zinc) than those consuming 30 or 1500ppm dietary zinc. The activities of GOT, GPT and alkaline phosphatase were lower in the rats consuming 30ppm zinc than those fed 0 or 1500ppm zinc diet. The activity of GOT was increased in rats consuming 0.35% phytic acid, whereas that of alkaline phosphatase was decreased in the rats fed phytic acid-containing diet. The concentration of phospholipid in serum was higher in rats fed 0.35% dietary phytick acid, whereas that of liver phospholipid was higher in zinc deficient groups, and increased by addition of dietary phytic acid. The concentration of triglyceride in serum from rats fed 30ppm zinc was lower than those fed 0 or 1500ppm zinc. On the other hand, liver triglyceride was higher in both the rats fed 30ppm zinc and 0.35% phytic acid. The concentration of serum total cholesterol was lower in the rats fed 30ppm zinc diet, and it was increased by addition of dietary phytic acid. But liver total cholesterol was higher in 30ppm zinc group. HDL-cholesterol in serum was the highest in both rats consuming 30ppm zinc and 0.35% dietary phytic acid, and the ratio of HDL-cholesterol to total cholesterol was higher in rats consuming 30ppm zinc diet. In conclusion, we suggest that coronary heart disease or liver disease can be prevented with phytic acid in rats which are fed the high zinc diet.
