Urine pH reached a steady state 3 days after switching from ordinary daily diets to specifiedregimens. The amount of acid generated ([SO42−] + organic acid−gut alkali)was linearly related with the excretion ofacid (titratable acid + [NH4+]−[HCO3−]), indicating that H+in urine is generated by the metabolic degradation offood materials. Uric acid and excreted urine pH retained a linear relationship, as reported previously. Among the fivefactors which are associated with calculating clearances for both uric acid and creatinine, we identified a conspicuousdifference between acidic and alkaline diets in the uric acid concentration in serum as well as in urine; uric acid in theserum was higher in the acidic group than in the alkaline group, while uric acid in the urine in the acidic group waslower than that in the alkaline group. These changes of uric acid in acidic urine and in serum were reflected in thereduction of its clearance. From these observations, it is considered that uric acid may be reabsorbed more actively inacidic urine than in alkaline urine.Conclusion:We conclude that alkalization of urine by eating nutritionally well-designed alkaline -prone food iseffective for removing uric acid from the body
