Senior author of the study Gary Curhan said, “Our study found that the relation between fluid intake and kidney stones may be dependent on the type of beverage consumed. We found that higher consumption of sugar-sweetened drinks was associated with a higher incidence of kidney stones.”
The researchers analyzed three ongoing cohort studies, which involved 194,095 participants followed for a median of eight years. All participants completed questionnaires regarding diet, medical history, lifestyle, etc.
Based on responses, the researchers found those participants who consumed sugary beverages like soda at least once a day had a 23 percent higher risk of developing kidney stones, compared to those who consumed them less than once a day. Coffee, orange juice, and tea were associated with a lower risk of kidney stones.
Corresponding author Pietro Manuel Ferraro said, “Our prospective study confirms that some beverages are associated with a lower risk of kidney stone formation, whereas others are associated with a higher risk. Although higher total fluid intake reduces the risk of stone formation, this information about individual beverages may be useful for general practitioners seeking to implement strategies to reduce stone formation in their patients.”
