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.
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.
Water
pollution:
The
artificial sweeteners used in diet sodas don't break down in our bodies, nor do
wastewater-treatment plants catch them before they enter waterways, researchers
have found. In 2009, Swiss scientists tested water samples from
wastewater-treatment plants, rivers and lakes in Switzerland and detected
levels of acesulfame K, sucralose, and saccharin, all of which are, or have
been, used in diet sodas. A recent test of 19 municipal water supplies in the
U.S. revealed the presence of sucralose in every one. It's not clear yet what
these low levels are doing to people, but past research has found that
sucralose in rivers and lakes interferes with some organisms' feeding habits.
