Did you know that your drink might contain an ingredient that is not used in beverages in 100 countries around the world?

Brominated vegetable oil (also known as “BVO”) is found in sports drinks and citrus-flavored sodas.  It is a chemical that keeps two liquids mixed together.  It acts as a binding agent, also known as an emulsifier, and it prevents the flavoring and other ingredients found in our drinks from separating and floating to the surface.

It makes sense , on one level, as we don’t want our drinks to look like a separated salad dressing with ingredients floating to the top!  But this appearance might come with a hidden side effect.  According to SHAPE magazine and nutritionist Mira Calton and her husband Jayson Calton, Ph.D., “Because it competes with iodine for receptor sites in the body, elevated levels of the stuff may lead to thyroid issues, such as hypothyroidism, autoimmune disease, and cancer,” Calton says. As if that wasn’t scary enough, BVO's main ingredient, bromine, is a chemical that is considered toxic. It's been linked to all kind of health concerns, including organ system damage, birth defects, schizophrenia, and hearing loss, which explains why it's been removed or banned from food and drinks in more than 100 countries.

These health concerns and the fact that so many countries have removed BVO from their beverages was so concerning to one 15 year old that she launched an online petition that landed her in the New York Times in which she called for the removal of this ingredient from American beverages, as it’s been removed from products around the world.

Want to opt out of brominated vegetable oil here in the United States? Skip the sports drinks and choose water.  And if you’re filling up your cup at the soda fountain, instead of the lemon-lime and citrus flavored drinks, consider drinking something else.

Remember, while none of us can do everything, all of us can do something.  Focus on progress not perfection, and do what you can, where you are with what you have, remembering not to make “the perfect” the enemy of “the good.”

So when it comes to Subway sandwiches, you'd think you were pretty safe, right?  I mean, if you had to trade up from a fast food burger and fries, that's where you might go.

But a recent article by a woman who calls herself "Food Babe" will stop you in your tracks.

In her efforts to eat "real food", she decided to ditch the processed stuff.  It was an interesting journey, to say the least, but nothing could have prepared her for what she found in her local Subway shop.

"Eat Fresh" At least, that's what she thought she was getting.

But when she decided to look under that plastic shield, she was absolutely stunned at what she found.

And while she goes into remarkable details about the chemicals that have been added to the ingredients used in those sandwiches to preserve their shelf life in the store, the details she gives about one of the ingredients in the bread are jaw-dropping.

Like many of us, we've eaten there, multiple times, and probably like "Food Babe" had absolutely no idea that this is what we were getting:

"The 9 grain wheat bread might look and smell freshly baked but it contains close to 50 ingredients including refined flours, dough conditioners, hidden MSG, refined sugars, etc.

Could bread this processed ever be real food?

Certainly not, when it includes a chemical ingredient called azodicarbonamide, which is banned as a food additive in the U.K., Europe, and Australia, and if you get caught using it in Singapore you can get up to 15 years in prison and can be fined $450,000.  Azodicarbonamide is more commonly used in the production of foamed plastics, however, it is allowed in the United States as a food additive, a flour bleaching agent, and a dough conditioner that improves elasticity of bread.

The U.K. has recognized this ingredient as a potential cause of asthma if inhaled, and advises against its use in people who have sensitivity to food dye allergies and other common allergies in food, because azodicarbonamide can exacerbate the symptoms."

It certainly makes you stop and think about what we have done to the U.S. food supply for the sake of profit margins.  And what we need to do to dig ourselves out of this chemical-heavy kitchen.  Researchers increasingly refer to certain chemicals that can promote weight gain as "obesogens."  Our grandmothers certainly didn't have that term, but now that we have it, books have been written about it, and increasing amounts of science are highlighting their effects.
