| Outline of Final Research Achievements |
Hyperphosphatemia in patients with chronic kidney disease is a factor involved in the development of serious complications such as cardiovascular diseases, so it is important to control dietary phosphate intake. However, it is difficult to achieve dietary phosphate restriction because protein sources contain high amounts of phosphate. Therefore, in this study, we focused on the difference in the absorption rate of phosphate contained in plant and animal foods. The subjects were provided with a diet rich in phosphate of plant or animal origin, and changes in serum phosphate levels were examined. As a result, the increase in serum phosphate levels were suppressed in subjects who consumed a diet rich in plant-derived phosphate as compared to subjects who consumed a diet rich in animal-derived phosphate. It was also suggested that this effect is related to dietary fiber, which is high contained in plant foods.
