Deceivingly "Diet"
(from Prevention Magazine)
Pop quiz! What’s the single biggest source of calories for
Americans? White bread? Big Macs? Actually, try soda. The average
American drinks about two cans of the stuff every day. “But I drink diet
soda,” you say. “With no calories or sugar, it’s the perfect
alternative for weight watchers…. Right?”
Not so fast. Before you pop the top off the caramel-colored bubbly, know this: guzzling diet soda comes with its own set of side effects that may harm your health—from kickstarting kidney problems to adding inches to your waistline.
Unfortunately, diet soda is more in vogue than ever. Kids consume the stuff at more than double the rate of last decade, according to research in the American Journal of Clinical Nutrition. Among adults, consumption has grown almost 25%.
But knowing these 7 side effects of drinking diet soda may help you kick the can for good.

But knowing these 7 side effects of drinking diet soda may help you kick the can for good.
Kidney Problems
Here’s something you didn’t know about your diet soda: It
might be bad for your kidneys. In an 11-year-long Harvard Medical School
study of more than 3,000 women, researchers found that diet cola is
associated with a two-fold increased risk for kidney decline. Kidney
function started declining when women drank more than two sodas a day.
Even more interesting: Since kidney decline was not associated with
sugar-sweetened sodas, researchers suspect that the diet sweeteners are
responsible.
Messed-Up Metabolism
According to a 2008 University of Minnesota study of almost
10,000 adults, even just one diet soda a day is linked to a 34% higher
risk of metabolic syndrome, the group of symptoms including belly fat
and high cholesterol that puts you at risk for heart disease. Whether
that link is attributed to an ingredient in diet soda or the drinkers’
eating habits is unclear. But is that one can really worth it?
Obesity
You read that right: Diet soda doesn’t help you lose weight
after all. A University of Texas Health Science Center study found that
the more diet sodas a person drank, the greater their risk of becoming
overweight. Downing just two or more cans a day increased waistlines by
500%. Why? Artificial sweeteners can disrupt the body’s natural ability
to regulate calorie intake based on the sweetness of foods, suggested an
animal study from Purdue University. That means people who consume diet
foods might be more likely to overeat, because your body is being
tricked into thinking it’s eating sugar, and you crave more.
A Terrible Hangover
Your first bad decision was ordering that Vodka Diet—and you
may make the next one sooner than you thought. Cocktails made with diet
soda get you drunker, faster, according to a study out of the Royal
Adelaide Hospital in Australia. That’s because sugar-free mixers allow
liquor to enter your bloodstream much quicker than those with sugar,
leaving you with a bigger buzz.
Cell Damage
Diet sodas contain something many regular sodas don’t: mold
inhibitors. They go by the names sodium benzoate or potassium benzoate,
and they’re in nearly all diet sodas. But many regular sodas, such as
Coke and Pepsi, don’t contain this preservative.
That’s bad news for diet drinkers. "These chemicals have the ability to cause severe damage to DNA in the mitochondria to the point that they totally inactivate it - they knock it out altogether,” Peter Piper, a professor of molecular biology and biotechnology at the University of Sheffield in the U.K., told a British newspaper in 1999. The preservative has also been linked to hives, asthma, and other allergic conditions, according to the Center for Science in the Public Interest.
Since then, some companies have phased out sodium benzoate. Diet Coke and Diet Pepsi have replaced it with another preservative, potassium benzoate. Both sodium and potassium benzoate were classified by the Food Commission in the UK as mild irritants to the skin, eyes, and mucous membranes.

Rotting Teeth
With a pH of 3.2, diet soda is very acidic. (As a point of
reference, the pH of battery acid is 1. Water is 7.) The acid is what
readily dissolves enamel, and just because a soda is diet doesn’t make
it acid-light. Adults who drink three or more sodas a day have worse
dental health, says a University of Michigan analysis of dental checkup
data. Soda drinkers had far greater decay, more missing teeth, and more
fillings.
