We already have to hold ourselves back from drinking soda. Is iced tea the latest beverage to get nixed from health conscious shelves?

Doctors in Arkansas diagnosed a man with kidney failure thanks to his iced tea habit, reports UK’s Guardian. But don’t throw out your Arizona Iced Tea just yet – the unidentified patient admits he drinks at least one gallon of iced tea per day.

This gentleman drank what amounts to 16 8-ounce cups of iced tea every single day, say doctors. Since black tea has a chemical called oxalate that can lead to kidney trouble, it’s no surprise that excessive amounts of the stuff would lead to renal failure. (Oxalate is also found in spinach, wheat bran, and chocolate— so maybe hold off on gorging on those as well.) According to Telegraph UK, the man has no family history of kidney disease. He also has diabetes, but doctors believe the cause to be his iced tea habit alone.

The Guardian reminds us that American adults on average drink a total of 10 or 11 cups of beverages per day. So 16 cups of iced tea is, clearly, a stretch. Someone get this guy a Brita water filter already.
