But I drink Diet!
The average American drinks two of these a day. 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%.
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.
Muffin Top - Fluff - Belly Fat? 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?
Mold Inhibitors? Diet Sodas contain the chemical known as sodium benzoate or potassium benzoate. These chemicals have been known to damage your DNA, cause hives, asthma, and other allergic conditions. Pepsi and Coke 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.
