Excessive tea consumption increases the risk of developing kidney stones
Is it true that excessive tea consumption increases the risk of developing kidney stones?
No. Current epidemiological, genetic, and experimental evidence refutes the claim that excessive tea consumption increases the risk of kidney stones, instead indicating that regular or heavy tea intake is associated with a reduced risk of nephrolithiasis.
Verdict: REFUTED · 0 sources for, 3 against · Last checked
The retrieved literature contains no papers supporting the claim that excessive tea consumption increases kidney stone risk. Conversely, multiple rigorous studies—including a large prospective cohort study combined with Mendelian randomization [11], population-based genetic analyses [8], and clinical case-control studies [6]—consistently demonstrate a protective inverse relationship between tea consumption and kidney stone formation. Therefore, the claim is refuted by the available evidence.
