Too much Cola can cause kidney problems

New York, Jan 22 (UNI) Drinking two or more colas a day-- whether artificially sweetened or regular-- is linked to a two-fold risk of chronic kidney disease, a study revealed.

Colas contain high levels of phosphoric acid, which has been linked to kidney stones and other renal problems, it said.

A team of scientists at the National Institutes of Health, US, compared the dietary habits of 465 people with chronic kidney disease and 467 healthy people, the New York Times reported.

It found that drinking too much cola can cause kidney problems.

However, drinking two or more non-cola carbonated drinks a day did not increase the risk, they said.

The authors of the study said more research is needed, but their findings support the long-held notion that something about cola-- the phosphoric acid, for example, or the ability of cola to pull calcium from bones-- seems to increase the risk of kidney stones, renal failure and other conditions affecting the kidneys.
