Outline of Final Research Achievements

Elevated serum phosphorus levels induce vascular calcification, arterial sclerosis and cardiovascular diseases. The purposes of this study were to evaluate whether a 24-h urine collection method could estimate dietary phosphorus intake, and to evaluate the effects of the timing of eating, especially nocturnal eating, on phosphorus metabolism. Our results indicate that estimation of dietary phosphorus intake with the 24-h urine collection method, using the amount of phosphorus and urea nitrogen excretion, may increase the precision of short-term monitoring. Also we revealed that nocturnal eating inhibits phosphorus excretion. It is suggested that nocturnal eating should be abstained from to manage serum phosphorus levels to within an adequate range.
