Dark-colored cola may cause kidney disease
It appears as though there may be a risk to drinking diet soda after all, although it has nothing to do with the alleged risk of obesity. Rather, there is evidence to suggest that drinking dark-colored diet cola (and dark-colored regular cola) can increase your risk of kidney disease.
Based on a report published in the journal Epidemiology, drinking two or more dark-colored sodas -- such as Coke, Pepsi, Dr. Pepper, and similar generic brands -- per day doubles your chances of kidney disease.
The phosphoric acid found in dark colas, but not in clear sodas such as Sprite and 7-Up, is what gives it its unique taste, but also what may lead to the development of kidney stones. This, in turn, can potentially lead to complications and disease.
I suppose this is yet another reason to just stick to plain ol' water.

dark sodas also cause UTI's for those that are already prone to them

I used to get horrible urinary tract infections when I was drinking Diet Pepsi. My urine was red with blood, very painful. I haven't touched soda or coffee in over 10 years and now drink cranberry juice and water.

I quit drinking dark colas and within a week my fibromyalgia went away. I've been pain-free for a year after ten years of suffering horrible pain. I came to the conclusion I had been poisioning myself.

I work in dialysis and our patients are not allowed to have dark colored sodas because of the phosphorus. Phosphorus can lead to heart attack, stroke or even death because that can build up and harden your arteries. And normal people can digest that out, my patients can't. But if they want to have a dark colored soda, they must take their binders with that. Moral of the story, stay away from dark colored sodas, even if you aren't on dialysis.

I agree completely. 14 years ago I did have kidney disease and my doctor told me then ... do NOT drink any dark colas. Only clear sodas.
Now I only drink Fresca.
Thanks for writing about this!
PS My kidneys are in great shape today!

I have to agree with this story.
For years I had problems with my bladder control. I was only 36 yrs old at the time.
Eventually it was discovered that I had a very rare tumor in my bladder. Luckily for me, the fine doctors at Cleveland Clinic were able to remove the tumor and save 2/3 of my bladder in the process.
I was told not to drink soda pop, and if I did, not to drink dark soda pop. The caramel color in it along with the phosphoric acid can cause problems for the bladder and the kidneys. Since that time, I only drink clear soda pop, if I drink any at all.

Yes, this is true. I always had the feeling that the Diet Pepsi my husband was drinking all day long for about 400 years was hurting him. He ended up with kidney stones, an operation for that, a triple bypass, present heaert problems, and has now been on dialysis for 4 years.

My 50-year-old wife drinks gallons of diet cola each month. Last year, she had kidney stones. She still drinks diet cola even though I've urged her to quit. I myself have consumed gallons of sugar cola over the years. I'm presently awaiting CT scan results for possible cysts on my kidneys. My family physician has warned me of possible diabetes from drinking so much sugar cola. As a nation of cola consumers, we all need to cut back on our ingesting of these poisons and toxins.

Oh give me a break! I've a friend who drinks 12 cans of diet pepsi a day; she's now 63 yrs old and she contracted colon cancer, not kidney disease. Her kidneys are in excellent shape. I drink one coca cola per day on average and I've drunk colas since childhood. My key issues are allergies. Stop with the fear tactics. Who's benefitting from these "studies" anyway? Follow the money.

My daughter gets kidney stones all the time. The first time she got them was 18 months olds ! The youngest that the docs had ever seen. AND she wasn't drinking soda then. She is now a teenager and gets them about every two years. She is a water drinker and doesn't like soft drinks but if she does drink one it usually a clear one. I think it in the genes and the environment. I live in the "Ohio Valley" and this area has the highest rate of kidney stones in the country!! Something in water ??

I agree with this topic totally!! I used to drink cokes like there was no tomorrow I woke up needing a coke and went to bed with one by my bed so anyway this lead to one night about 2am of me wakeing up with severe pain in my left side I thought I was going to die it hurt so bad. I got to the hospital and it turned out to be kidney stones! I was admitted for 4 days I had blood in my urine and had to have surgery to remove the stones so a bad habit caused me to have a very expensive mistake of just over 15,000 dollars in hospital bills I do not drink dark drinks any more!! I strongly caution anyone with this habit please try to stop b4 it happens to u as well.
