Lie #4: Natural and organic lunchmeat is good for you.

The truth: The American Cancer Society recommends avoiding processed meats (including lunchmeat) as much as possible, thanks to the products' association to colon cancer. While it's a huge plus that organic lunchmeats are free of genetically engineered ingredients, pesticides, hormones, and antibiotics, they still likely harbor nitrites. Plus, many poultry-based lunchmeats also contain carrageenan, a seaweed-derived additive used to bond the meat together. There's strong evidence that carrageenan creates inflammation and causes digestive diseases, including ulcerative colitis.

Eat this instead: It's best to limit the amount of lunchmeat you eat, but when you do, opt for an organic lunchmeat option that doesn't list carregeenan on the ingredients label, such as Applegate's roast beef, Genoa salami, or uncured ham products. Avoid carrageenan in other poultry products like chicken strips, too.
