Only the idea of a kidney stone can make you cringe in discomfort, especially when you consider that 10% of people have a kidney stone at some point in their lives, according to the National Kidney Foundation. To help you avoid being part of that stat, a research team found that a popular strain of tea can help keep the development of kidney stones at bay.
Previous research has shown that drinking too much coffee and Soft drink can sometimes lead to kidney stones, because “anti-nutrients” in these drinks can affect how effectively the body can absorb some nutrients.
In a review published last month in the peer-reviewed World news of Urology, a team of researchers in France and the UK set out to investigate the relationship between coffee and tea and kidney stone formation.
After reviewing 13 previous studies, the researchers concluded that drinking appropriate amounts of both coffees and tea may have a protective effect against the formation of kidney stones. This is because consuming caffeine increases the excretion of calcium, sodium and magnesium through the urine.
However, the researchers specified that a special type of tea may be the best defense against the development of kidney stones. “The currently available literature generally supports a potentially protective role for tea against stone formation, especially for green tea,” the study authors write.
The water the tea is steeped in helps the body produce urine, which facilitates the release of excess minerals, the researchers note. They also suggest that tea’s antioxidants may have a preventative effect.
More research is needed before the scientific community can definitively claim that coffee or tea prevents kidney stones. However, if you already have some green tea in your cupboard, this study can be a great source of inspiration to light the kettle.
If you’re a coffee drinker, researchers also recently discovered that there’s a certain amount that can lower your coffee fatal risk of cardiovascular disease.
