Want to feel better about what you're eating? Want to be able to check the safety of the unpronounceable ingredients you see on the label while you're in the grocery store? The iPhone app Don't Eat That can help.

On his 50th birthday, Dwayne Ratleff decided to get healthy. To do that, he decided he had a lot to learn about nutrition. He spent nearly 1000 hours compiling a database using information from the Food and Drug Administration, the European Food Safety Agency, Food Standards Australia New Zealand, the World Health Organization, and many more. He doesn't claim to be a doctor or nutritionist, but he has used the best sources available to put together a database with the best information available on additives in our food.

What's especially interesting is the times when these protective organizations disagree. The FDA has allowed that additive to be used in food in the United States, but how do you feel when you discover that it has been banned in Australia? Don't Eat That allows search by ingredient name, and includes separate listings of things harmful to kids, carcinogens, items developed through genetic modification, and warnings of things that can be allergens or problems for asthmatics.

It's available for $1.99 from the app store, and the developer encourages you to help keep it up to date by submitting your own additional information on ingredients to be included in future updates.
