5 Ingredients You Never Want to See in Your Food

If you want to live a healthy life, there are certain things you should never consume. Read our rogue's gallery of food ingredients you want to avoid.

Here's a secret.

A healthy diet isn't complex. It doesn't require punishing yourself with monthly cleanses or self-deprivation. Simply live by the rule "if you can't read it, don't eat it."

Here's a secret.

A healthy diet isn't complex. It doesn't require punishing yourself with monthly cleanses or self-deprivation. Simply live by the rule "if you can't read it, don't eat it."

Have you ever looked at some of your favorite food labels? Some of them look like a high school chemistry project.

It's generally understood that processed foods aren't the best. Some have been linked to pretty scary health risks. Or they're just gross—for instance, carmine, a red food coloring, is made from ground up cochineal insects.

Check out the following five ingredients you never want to see in your box of cereal or soup can.

Sodium Nitrates

A common preservative typically found in lunchmeat and pork products (bacon, ham, and sausages). Several studies have marked sodium nitrates/nitrites as carcinogens. The FDA allows their use only because they prevent bacteria growth and maintain meat's pink hue.

Hydrogenated Vegetable Oil

Food scientists created partially hydrogenated and fully hydrogenated oils as a replacement for saturated fats. Nevertheless, they are still a form of trans fat, which research shows is the worst fat for your body.

Trans fats have been linked to inflammation, cancer, diabetes, Alzheimer's and cardiovascular disease. Common commercial foods that include hydrogenated vegetable oils include peanut butter, cookies, cakes and salad dressings.

High-Fructose Corn Syrup

You're probably already aware of the controversy surrounding HFCS. Research has presented troubling concerns over links between HFCS and diabetes as well as weight gain and Alzheimer's disease.

A relatively inexpensive sweetener compared to sugar, HFCS is probably lurking inside some of your favorite foods, like sodas, salad dressings, bread (including both white and whole wheat), pastries and condiments. (See Fact or Myth: Is High Fructose Corn Syrup The Worst Sweetener of Them All?)


A chemical sweetener, aspartame does not raise blood sugar, which is why it's often marketed to people with diabetes. However, recent research has shown it can raise insulin levels, which can promote fat storage. One study suggested that aspartame-sweetened beverages (diet soda and flavored waters) may promote obesity rather than fight it. Participants in the study who consumed aspartame-sweetened beverages gained more abdominal weight than those who consumed sugar-sweetened beverages.

Monosodium Glutamate

Another flavor enhancer and preservative, monosodium glutamate (MSG) is a growing health concern. Some research shows that monosodium glutamate promotes weight gain, as well as other toxic effects in the body and the brain.
