Joanne Tobacman, MD, an assistant professor in the department of internal medicine at the University of Iowa, is a leading researcher of this seaweed extract, used as a thickening agent in many foods, including soy milk and ice cream. "Many careful animal studies consistently demonstrate intestinal inflammation caused by carrageenan exposure. For that reason, I think it's a good idea to avoid carrageenan-containing food products," she advises.

Their worry is based upon exploration investigations of carrageenan by Dr. Joanne Tobacman, a partner teacher at the University of Illinois in Chicago, who made cases this normally happening kelp subsidiary causes gastrointestinal irritation and pre-harmful sores when nourished to little lab creatures.

What numerous don't understand is that Dr. Tobacman was really concentrating on a molecular corrupted type of carrageenan called poligeenan, which has never been utilized as a part of nourishment applications, and is utilized as a part of different applications, for example, barium contrast answer for X-beams and CT examines.

The result: "It predictably causes inflammation, which can lead to ulcerations and bleeding," explains veteran researcher Joanne Tobacman, MD, associate professor of clinical medicine at the University of Illinois School of Medicine at Chicago.

She says the food ingredient irritates by activating an immune response that dials up inflammation. And we all know by now, that we are always trying to reduce inflammation, right??
Dr. Tobacman also told the board that in the past, drug investigators actually used carrageenan to cause inflammation in tissues in order to test the anti-inflammatory properties of new drugs. And she reported further that when laboratory mice are exposed to low concentrations of carrageenan for 18 days, they develop "profound" glucose intolerance and impaired insulin action, both of which can lead to diabetes."

Joanne K. Tobacman, M.D., associate professor of clinical medicine at the University of Illinois College of Medicine, whose body of work focuses on clarifying and making known the effects of carrageenan on the human and animal body, reported in her 2001 review published in the journal Environmental Health Perspectives that:

Dr. Tobacman also shared that "research suggests that acid digestion, heating, bacterial action and mechanical processing can all accelerate degradation of food-grade carrageenan.

A: It clearly has to be attributed to the research of Dr. Joanne Tobacman, an Associate Professor at the University of Illinois in Chicago. She and a group of molecular biologists have accused carrageenan of being a potential inflammatory agent as a conclusion from laboratory experiments with cells of the digestive tract. It requires a lot of unproven assumptions to even suggest that consumption of carrageenan in the human diet causes inflammatory diseases of the digestive tract. The objectivity of the Chicago research is also flawed by the fact that Dr. Tobacman has tried to have carrageenan declared an unsafe food additive on weak technical arguments that she broadcast widely a decade before the University of Chicago research began.

On June 11, 2008, Dr. Joanne Tobacman petitioned the FDA to revoke the current regulations permitting use of carrageenan as a food additive. On June 11, 2012 the FDA denied her petition, categorically addressing and ultimately dismissing all of her claims; their rebuttal supported by the results of several in-depth, scientific studies.
