Why Drinking Too Much Iced Tea Caused This Mans Kidneys To Fail

Dr. Hammontree discussing ice tea effects of Kidney stones

Iced tea is delicious no one here is denying that. But like with most great things, too much of it can bring about dire consequences.

Such is the story of an Arkansas man who drank so much iced tea that it led him to develop kidney failure. Three Arkansas doctors described the case in a letter published by the New England Journal of Medicine this week.

The 56-year-old man showed up at the hospital in May 2014 with weakness, fatigue and body aches, along with high levels of creatinine, which is used as an indicator for kidney function.

Doctors asked: Do you have a history of kidney stones in your family? No.

What about kidney disease? No.

The questions continued, the doctors write, until eventually âthe patient admitted to drinking sixteen 8-oz glasses of iced tea daily.â

Yeah, thatâs a lot of iced tea. A gallon of it, actually.

Black tea is rich in the food compound oxalate, which had likely clogged the manâs kidneys and inflamed them, leading to renal failure and the need for dialysis.

âIn this case there were oxalate crystals inside the kidney, and that generates an inflammatory reaction,â Umbar Ghaffar of the University of Arkansas for Medical Sciences told Reuters. âIf thatâs not resolved it will cause scarring and loss of the kidney tissue. So thatâs what probably was happening in this patient.â

But at 16 cups of black iced tea a day, the Arkansas patient took in more than 1,500 milligrams of oxalate every day.

So, bottoms up â to a limit.

Diet And Risk For Developing Kidney Disease

I was diagnosed with minimal changes disease, and I am very interested in research that shows lifestyle patterns that affect kidney disease. I was diagnosed 18 years ago and have spent the past two decades successfully experimenting with food and how protein affects my kidney disease. By replacing animal protein with plant-based protein, I was able to put my CKD into remission.

In this issue of the Clinical Journal of the American Society of Nephrology, Rebholz et al. research the effect of sugar-sweetened beverages on kidney disease risk. Important studies, such as this one, motivate me to restrict my consumption of sugar-sweetened drinks and help educate other patients with kidney disease on the affect that sugar-sweetened beverages have on kidneys.

It is common practice in restaurants to allow employees to drink sodas for free. During the hot summer months, I was drinking more sodas per shift. This increase in sugar-sweetened beverages made me less tolerant of the heat in the kitchen. I appreciate my physical response, because it motivated me to change my beverage consumption from sodas to fruit-infused flavored water. Chances are I could have decreased my kidney function even more if I had not made this lifestyle change. I look back on that situation and realize that my experience does support these research findings: a higher intake of soda could be associated with greater odds of decreasing kidney function.

There is Risk By Association

Among diabetic young men, use of diet, but not sugared, sodas was associated with higher average blood glucose. This was ascribed not so much to the beverages as to the generally unhealthy life style of those who consumed larger amounts of such beverages. Likewise, in another study, diet sodas were associated with new onset of type 2 diabetes in men. But with full adjustment for other factors that might predispose to diabetes, the effect of diet soda disappeared. It seems as if men who were trying to lose weight, or compensate for high diabetic risk, preferentially used diet sodas.

Cola vs Uncola

Given that there are drawbacks to sugared sodas and no benefits to diet sodas, what about the clear sodas the non-cola drinks, as a special case?

7UP and Sprite have no caffeine which may be an advantage for some people.
