Your new tool for food label sleuthing.

Have you ever turned over a box of cereal, read the ingredients label, and wondered: "What exactly is Yellow #5?"

If you knew it was derived from coal tar, would you still eat it?

Now, Don't Eat That, a brand new iPhone app, allows you to investigate before dropping the item into your grocery cart. I took a test spin of Don't Eat That today on my iPhone, and here is what I discovered:

Carmine is a red dye found in ice cream, yogurt, eye shadow, and lipstick. It is made from the scaled insect Cochineal. Upon further investigation, I discovered that it is prepared by boiling the dried insect in water.

Natural flavors are considered "trade secrets," and therefore, the FDA does not require them to be listed on a food label. (I had always wondered why certain ingredients got a free pass and didn't have to be specifically mentioned).

Overall, there are a staggering number of food dyes derived from coal tar. And many are used in kids' cereals, which I confirmed today after looking at a box of Cap'n Crunch.
