Summary
We studied urinary calcium and oxalate excretion in response to oral fructose load
and to oral glucose load each on two different randomized mornings in twelve healthy
subjects. Oral fructose load provoked an increase in calciuria and a decrease in oxaluria
while oral glucose load induced an increase in both calciuria and oxaluria.
These results suggested that in healthy subjects, the decrease in oxaluria observed
during fructose load reduced the product urinary [calcium] × [oxalate] which was the
main factor in the genesis of urinary calcium oxalate stones while glucose load increased
the risks of urolithiasis by means of the rise in both calciuria and oxaluria.
