I just read an article about carageenan being a carcinogen, and started checking labels of canned pet foods and found it is tough to find one without carageenan. What does Dr. Wysong think of carageenan as a food ingredient? The article I read said it is a carcinogen for both humans and pets. I don't see it listed in the few Wysong foods I surfed but it is pretty much in everything else.
Keep in mind that everything is a potential carcinogen and studies can be found arguing the dangers of practically anything. But it is the dose that makes the poison. This would apply to carageenan as well.
