The tricky thing that other people need to be aware of is that this ingredient is not listed on every product that it might be included in, especially chocolate.
He also found that several different chocolates cause similar yet milder problems, and it wasn't until he contacted companies and demanded that they find out what additional products might have been used but aren't listed (because of loopholes in the laws) that he found this same ingredient used as a thickening agent in chocolate processing.
I'm sharing this information to alert others to warn them about what kind of "natural" substances can also be harmful (carrageenan is made from Irish moss, or seaweed so it appeals to vegetarians and is used in many vegetarian foods ;like Tofu) and how to keep track of what you eat in a journal every single day for every thing you eat and drink.
Write down all of the ingredients or keep wrappers and boxes. Immediately following an outbreak, look over the ingredients in the last 24 hours and compare them to everything else that has been safely consumed to find the ingredients that are upsetting the body. There is so much information available online, you just have to know where to look and find it.
Even though I have never personally experienced any negative effects of carrageenan that I know of, evidence seems to show that carageenan is a harmful food additive. What I learned about carrageenan is enough to convince me to avoid it as much as possible!

Are You Allergic to These 10 Everyday Items?
I am highly, highly allergic to Carageenan. It took years to figure this out through process of elimination. The problem still is that so many food processors hide it in their products without including it on the label. I know, my immune system is like a blood hound in finding it in my system. The first alarm is a little itch that ultimately leads to a boil that is so very painful. My head aches and my body aches as if I were catching the flu. Sometimes it is incapacitating. The boil comes to a head and after it is fully drained, only then do I get relief. The doctors have cultured the discharge and said its only Staph. Sometimes I need antibiotics to get over it because another boil can pop up right next to the old one. Guess what, it runs in families too. So its information you want to share with them so those with the same condition don't suffer alone for years trying to figure out what the cause is. I wish this issue would get more exposure so that something would be done to abolish this ingredient altogether. I guess not until more people are affected will it be properly addressed. Thank you for this article. I don't feel so alone.
I get those boils as well (in very annoying places) and have had to go through a month of antibiotics. Suddenly it was back. Why? I was out here doing research. I compared the ingredients of the things that seems to cause it (slim fast, instant breakfast, and now this specific brand of frozen yogart). The ingredients they have in common were cocoa (but I can eat chococate with no problem), maltodextrin (which I found is in Splenda which doesn't give me a problem) and this carageenan. When I read your reply I had an AH-HA moment. I will now avoid this ingredient. Thank you for your post. It was most helpful.
