5 great reasons to kick your soda habit

If you\'ve been reading health magazines and websites for any length of time, you\'ve read a litany of reasons why soda is bad for you. It\'s nothing but sugar water. It\'s devoid of any nutritional value. It leads to obesity and diabetes. But we\'ve dug up several other disturbing facts about what soda does to your body, besides packing on the pounds, that don\'t get much attention in broader discussions about soda and its impact on your health. Accelerated aging Diet or regular, all colas contain phosphates, or phosphoric acid, a weak acid that gives colas their tangy flavor and improves their shelf life. Although it exists in many whole foods, such as meat, dairy, and nuts, too much phosphoric acid can lead to heart and kidney problems, muscle loss, and osteoporosis, and one study suggests it could trigger accelerated aging. The study, published in a 2010 issue of the FASEB Journal, found that the excessive phosphate levels found in sodas caused lab rats to die a full five weeks earlier than the rats whose diets had more normal phosphate levels—a disturbing trend considering that soda manufacturers have been increasing the levels of phosphoric acid in their products over the past few decades. Caramel cancer-causers In 2011, the nonprofit Center for Science in the Public Interest petitioned the Food and Drug Administration to ban the artificial caramel coloring used to make Coke, Pepsi, and other colas brown. The reason: Two contaminants in the coloring, 2-methylimidazole and 4-methylimidazole, have been found to cause cancer in animals, a threat the group says is unnecessary, considering that the coloring is purely cosmetic. According to California\'s strict Proposition 65 list of chemicals known to cause cancer, just 16 micrograms per person per day of 4-methylimidazole is enough to pose a cancer threat, and most popular brown colas, both diet and regular, contain 200 micrograms per 20-ounce bottle. The Hidden Cancer Threat in Soda Mountain Dew mind Dentists have a name for the condition they see in a lot of kids who drink too much Mountain Dew. They wind up with a \"Mountain Dew Mouth,\" full of cavities caused by the drink\'s excessive sugar levels. \"Mountain Dew Mind\" may be the next medical condition that gets named after the stuff. An ingredient called brominated vegetable oil, or BVO, added to prevent the flavoring from separating from the drink, is an industrial chemical used as a flame retardant in plastics. Also found in other citrus-based soft drinks and sports drinks, the chemical has been known to cause memory loss and nerve disorders when consumed in large quantities. Researchers also suspect that, like brominated flame retardants used in furniture foam, the chemical builds up in body fat, possibly causing behavioral problems, infertility, and lesions on heart muscles over time. Toxic cans It\'s not just the soda that\'s causing all the problems. Nearly all aluminum soda cans are lined with an epoxy resin called bisphenol A (BPA), used to keep the acids in soda from reacting with the metal. BPA is known to interfere with hormones, and has been linked to everything from infertility to obesity to some forms of reproductive cancers. The Centers for Disease Control and Prevention have pegged soda cans, along with restaurant, school, and fast-food meals, as a major source of exposure to the chemical. And while Pepsi and Coke are currently locked in a battle to see which company can be the first to develop a 100 percent plant-based-plastic bottle—which they\'re touting as \"BPA free\"—neither company is willing to switch to BPA-free aluminum cans.
