Food Therapy: Coffee In Risk of Kidney Stone?

By Kyle J. Norton

Whole food ingredients in herbal plant have been found to process some significant effects in reduced risk and treatment of certain diseases, but single ingredient isolated from such plants may induce opposite outcomes. In compared to herbal medicine, food therapy even takes longer to ease symptoms, depending to stages of the treatment which directly address to the cause of disease.
Epidemiological studies linking coffee and caffeine intake in risk of kidney stone formation have been contradictory.

Coffee, a popular and social beverage all over the world, particular in the West, is a drink made from roast bean from the Coffea plant, native to tropical Africa and Madagascar.

Kidney stone is a deposit of insoluble calcium compounds in the kidney, affecting over 10% of world population, according to statistic.

According to the Warsaw Agricultural University, coffee and tea consumed daily and regularly expressed an increased risk of kidney stone by more than 80% in compared to risk of other factors, probably due to presence of oxalates found in coffee.

In fact, in the analyzed nutritional habits of 22 stone formers with special regard to oxalate content as one of the main nutritional lithogenic factors associated with kidney stones, researchers found that  risk of kidney stone increased substantially for men and women if dietary oxalate intake was over 354 mg and 406 mg, respectively

Contrastively, a prospective study in investigated relation between intake of 21 different beverages and risk of symptomatic kidney stones in a cohort of 45,289 men, 40-75 years of age conducted by the Harvard School of Public Health, suggested that the risk of stone formation decreased by 10%. of the amount for each 240-ml (8-oz) serving consumed daily in caffeinated coffee.

Other, in the analyzed association between intake of caffeine and incidence of kidney stones in 3 large ongoing cohort studies, and the Nurses' Health Studies (NHS) I and II also found a contradictory result in related to coffee and other plant base caffeine products.

In a total of 217,883 participants; over a median follow-up of >8 y, 4982 incident cases of kidney stone occurred studies, researchers files the following results.
1. The highest quintile of caffeine intake (95% CI: 12%, 38%) showed a significant reduced risk of developing stones by 26%, according to the Health Professionals Follow-Up Study (HPFS).
2. Caffeine inkate showed a 29 % lower risk in the NHS I cohort, and
3. and 31% lower risk in the NHS II cohort

Dr. the lead author said. "Among 6033 participants with 24-h urine data, the intake of caffeine was associated with higher urine volume, calcium, and potassium and with lower urine oxalate and supersaturation for calcium oxalate and uric acid".

Taking altogether, the findings demonstrated a contradictory result between caffeine and caffeinated and decaffeinated coffee intake and risk of formation of kidney stones, therefore, a cohost with large sample size study are warranted.
