Have you ever read the ingredients section on the back of a food box, package or wrapper and said to yourself, what the heck are these ingredients?
Most of the ingredients are real tongue twisters, just saying them is hard to do, but knowing what each ingredient is, well that is another story all
I recently read a CNN article explaining 6 food additives. Here is that article, I looked up each one and found pictures to add to this thread.
1. Xanthan gum
Sure the word "xanthan" sounds a little ominous, and yes, the stuff is made from the bacteria that cause black rot on broccoli plants. But
xanthan gum is a pretty benign substance. When the bacteria (called Xanthomonas campestris, if you're a scientist) is mixed with corn sugar, it
produces a tasteless, colorless goop that can be used as a thickener. It keeps ice cream from crystallizing and is what gives gluten-free bread its
spongy texture. Some people may be allergic to it, but it's pretty much as harmless as you can get.
2. Tertiary butylhydroquinone
In his book "The Omnivore's Dilemma," Michael Pollan wrote that this additive –- known as TBHQ -– was "perhaps the most alarming
ingredient" in a chicken nugget. He listed a bunch of terrifying symptoms that might result from ingesting a single gram of the stuff. Of course, to
get a whole gram, you'd need to eat over 300 nuggets at one sitting. So while TBHQ is pretty nasty stuff, it probably won't do anything bad to you
in the short term. It's an antioxidant; it keeps cooking oil from going bad. Derived from petroleum, it's also popularly used in paints and
3. Sodium stearoyl lactylate
You know how you use the expression "like oil and water" for two things that will never blend? Through the magic science of sodium stearoyl
lactylate, oil and water blend perfectly well. It's used in flour tortillas and many other packed baked goods. No studies have shown it to be
harmful, but because the chemical is made from lactic acid, it does tend to make vegans a little nervous. Most of what's used in food comes from
cocoa butter and other vegetable sources, though, so they can eat all the tortillas they want.
4. Phosphoric acid
That tangy "bite" you feel when you take a swig of cola comes from phosphoric acid, an inexpensive chemical made from minerals treated with
sulfuric acid. It's also used in paint stripper, but in much higher concentrations. Those stories you might have heard about soda melting metal
aren't really true; soft drinks aren't any more corrosive than orange juice. But the jury's till out on phosphoric acid. Some studies have
suggested that it can leach calcium out of the body, leading to weaker bones.
5. Cochineal extract
Good news: cochineal extract is all natural and has been used as a coloring for centuries. Possibly gross news: It's made from bugs. Tiny insects
that live on cactuses in Mexico and South America are dried and crushed to make the bright red coloring. The Aztecs dyed their clothing with it. Since
several artificial red food colorings were found to cause cancer, it's been used more in food. You can find it juice drinks, processed meats, cheese
and cookies (a more refined version is known as carmine or Natural Red #4). Some people have mild allergic reactions, but other than the ick factor,
there's nothing harmful about the substance.
6. Soy lecithin
Soy lecithin shows up in a lot of ingredient lists. In candy bars, it keeps the cocoa and the cocoa butter from separating; in baked goods, it
makes the dough less sticky. It's a natural product, chemically extracted from the sludge left over after pressing soybean oil. While some anti-soy
crusaders claim it should be avoided, other studies suggest that it could lower your cholesterol: It contains the nutrient choline, which is a popular
supplement in vitamin shops.
There you have it, 6 additives off your list if you didn't know them before.
