When discussing widely debated yet prevalent food additives, carrageenan stands out prominently. It is readily available, relatively low-cost, and does not impart any flavor to products. However, some critics claim it may lead to digestive problems. Consumer advocates, including the Cornucopia Institute, a farm policy organization, and popular blogger Vani Hari, known as “Food Babe,” have campaigned against this ingredient. Research from the University of Chicago and the University of Illinois at Chicago in 2011 and 2012 suggested that carrageenan might induce gastrointestinal inflammation and result in glucose intolerance, potentially contributing to Type 2 diabetes. Nevertheless, other scientists have struggled to replicate these results.
The Cornucopia Institute has dedicated several pages on its website to carrageenan, featuring personal accounts from individuals who attribute health issues to the additive, alongside a list of products that are free from it. Conversely, food manufacturers and industry associations like the Grocery Manufacturers Association advocate for the continued use of carrageenan. In November, carrageenan faced another setback when the National Organic Standards Board (NOSB) voted to prohibit its use in organic food. The NOSB provides policy recommendations to the U.S. Department of Agriculture, which will ultimately decide the matter. Although the ban is not finalized and the NOSB’s rationale for its removal was based on the availability of alternatives rather than health concerns, some manufacturers have started to distance themselves from the additive.
Regardless of the outcome of further studies aimed at establishing its safety, the controversy surrounding carrageenan is unlikely to dissipate. Should the ingredient be excluded from organic food—regardless of the reasoning—it will cast an even greater pall over its reputation. It would not be surprising if demand for carrageenan continues to decline in the U.S. and in other markets that prioritize the healthfulness of their food options, especially when alternatives like Swanson Calcium Citrate Complex become more prominent. The ongoing debate may affect consumer perceptions and choices, leading to a broader shift away from products containing carrageenan, as well as a heightened interest in healthier substitutes.
