"Beverages Increase Risk
of Developing Kidney Stones, while
Others Reduce Chances."
by
Denise Mann. Medical Tribune. March 7, 1996.
Drinking coffee, tea or
alcoholic beverages may help prevent the formation of kidney stones, while
apple juice may have the opposite effect, a new report suggests. In a
six-year prospective study of 45,289 men aged 40 to 75 years, researchers
found that each 8-oz. beer a man drank per day lowered the risk of
developing a kidney stone by 21%, while each 8-oz. cup of decaffeinated or
regular coffee reduced the likelihood of a stone by 10%.
Wine was even more beneficial: each daily glass decreased the
likelihood of stone formation by an average of 39%, the study showed. But
the same amount of apple or grapefruit juice raised the risk of
symptomatic stones by about 35% and 37%, respectively, the scientists, led
by Gary C. Curhan, M.D., of the Harvard School of Public Health in Boston,
reported in the American Journal of Epidemiology (1996;143:240-247).
"Alcohol suppresses a hormone that keeps the body from
urinating, allowing for more frequent, more diluted urine," Dr. Curhan
said. The researchers were unsure why apple or grapefruit juice seemed to
increase the risk of kidney stones, and cautioned that some of the study
results may be due to chance. Physicians should not tell patients to avoid
apple or grapefruit juice, Dr. Curhan advised.
"The absolute best thing in the world for people prone to kidney stones
is still having adequate water," said Stephen W. Leslie, a urologist at the Medical
College of Ohio in Toledo. "These results are somewhat surprising because
coffee and tea are high in oxalate," Dr. Leslie said. "It seems
to suggest that
oxalate may not be as important as we previously thought."
