Carrageenan

What it is: Do you eat seaweed? If you said no, prepare for a surprise, because carageenan is everywhere. Extracted from seaweed, carrageenan is a gel used as a thickening agent and emulsifier (keeps food from separating.)

Where you'll find it: May be injected into raw chicken or other meat as a way to retain water, as well as in dairy products like cottage cheese and ice cream. Chocolate milk often contains carrageenan to keep the cocoa from separating from the milk.

Gross-out factor: Low

About castoreum: so at some point in history, somebody actually sniffed and licked a beaver'sass and discovered it smelled and tasted good. LOL

CBS apparently doesn't keep up with the news; salt has (once again) been found not to be a health issue for the vast majority of people.

Some people, like me, are allergic to shellac. It can be sprayed on apples and is also used to coat capsules. If you are allergic it can cause fierce itching, scabbing and even welts. It is very difficult to discover if the apple you ate was sprayed or if you have ingested it in candy or capsules or something else. Fruit and vegetables should be required to provide labels with this information! Beware.
