Colas and kidneys

Short piece in today's Times about kidney disease.

"In a study published in the journal Epidemiology, the team compared the dietary habits of 465 people with chronic kidney disease and 467 healthy people. After controlling for various factors, the team found that drinking two or more colas a day — whether artificially sweetened or regular — was linked to a twofold risk of chronic kidney disease."

It's specific to colas, not carbonated drinks in general. The problems are kidney stones and kidney failure; cancer isn't mentioned, and I haven't been a big cola drinker for a long time, so I doubt this was a factor in my kidney cancer. But it's good to know.
