RE: Exposure to Carrageenan (food additive) may reduce DHEAS in the body

I agree. Though tangentally, I don't think that the benefits of anti-inflammatories match people's health expectations. More particularly, I feel that some anti-inflammatories like the Omega-3s have been oversold a little. They do have many benefits, but they can also suppress immune function. And there are enough of serious issues with trying to use aspirin to prevent a heart attack that I hope noone tries it anymore.
Okay, so I've spent a few hours looking over this stuff... I'm surprised I haven't heard of these problems before and there's not more resistance to Carrageenan's use. This stuff sounds deeply problematic. If it's paranoia, count me among the paranoid.
Quote:Carrageenan is sulfated polysaccharide which has been extensively used as emulsifier and thickening agent in the food industry, for its ability to induce acute inflammation in pharmacology and for its selectively toxic effect for macrophages in immunology.

Carrageenan, a component of the barium enema solution, produced positive reactions to allergy skin test and RAST. Gastrointestinal symptoms for which the patient was being investigated by the barium enema subsequently disappeared with a diet free of carrageenan.

Rapid production of ulcerative disease of the colon in newly-weaned guinea-pigs by degraded carrageenan.
Marcus AJ, Marcus SN, Marcus R, Watt J.
In a dose-response study, degraded carrageenan (Eucheuma spinosum) was supplied in the drinking fluid at 1.2 and 3% concentrations over two weeks to young adult guinea-pigs. Ulceration of the large bowel was produced in 100% of animals, the severity and extent of damage probably being dose-related. In a time-course study, 3% degraded carrageenan solution supplied to newly-weaned guinea-pigs produced in 100% of animals ulceration in the caecum by four days and in the ascending colon by seven days. The onset of ulceration occurred as early as the second day. This model is convenient and economic for the screening of drugs of potential therapeutic value in human ulcerative colitis.

A spokesman for the U.S. Food and Drug Administration (FDA) says there are two kinds of carrageenan -- undegraded and degraded. Undegraded carrageenan is what has been approved by the FDA for use in food. Degraded carrageenan has changed into a different substance and really isn't carrageenan anymore, says the spokesperson, and that is often what's been used in research studies.
According to the FDA, carrageenan is considered safe when manufactured according to FDA guidelines. Tobacman, however, says that virtually all carrageenan changes into degraded carrageenan. She says even when manufacturers use undegraded carrageenan, food preparation and the acid in our stomachs inevitably break some of the substance down into degraded carrageenan.

Quote:a) degraded carrageenan produces neoplasms and ulcerations in animal models;
b) acid hydrolysis, such as occurs in the stomach, leads to the production of degraded carrageenan from food-grade carrageenan; and
c) food-grade carrageenan contains significant amounts of degraded carrageenan.
Human consumption of carrageenan has been increasing steadily in the United States in the
20th century.

Quote:In this article I review the association between exposure to carrageenan and the occurrence of colonic ulcerations and gastrointestinal neoplasms in animal models. Although the International Agency for Research on Cancer in 1982 identified sufficient evidence for the carcinogenicity of degraded carrageenan in animals to regard it as posing a carcinogenic risk to humans, carrageenan is still used widely as a thickener, stabilizer, and texturizer in a variety of processed foods prevalent in the Western diet. I reviewed experimental data pertaining to carrageenan's effects with particular attention to the occurrence of ulcerations and neoplasms in association with exposure to carrageenan. In addition, I reviewed from established sources mechanisms for production of degraded carrageenan from undegraded or native carrageenan and data with regard to carrageenan intake. Review of these data demonstrated that exposure to undegraded as well as to degraded carrageenan was associated with the occurrence of intestinal ulcerations and neoplasms. This association may be attributed to contamination of undegraded carrageenan by components of low molecular weight, spontaneous metabolism of undegraded carrageenan by acid hydrolysis under conditions of normal digestion, or the interactions with intestinal bacteria. Although in 1972, the U.S. Food and Drug Administration considered restricting dietary carrageenan to an average molecular weight > 100,000, this resolution did not prevail, and no subsequent regulation has restricted use. Because of the acknowledged carcinogenic properties of degraded carrageenan in animal models and the cancer-promoting effects of undegraded carrageenan in experimental models, the widespread use of carrageenan in the Western diet should be reconsidered.
