1. What Is Carrageenan and Why Is It Used?
Carrageenan is a natural polysaccharide extracted from red seaweed, primarily Chondrus crispus, Eucheuma cottonii, and Eucheuma spinosum. It acts as a thickener, stabilizer, and emulsifier in various food products. According to a study published in the Journal of Food Science, carrageenan enhances texture and prevents separation in many processed foods. Carrageenan is favored by manufacturers because of its ability to create smooth, appealing textures and extend shelf life in a cost-effective manner.
1.1. Key Properties of Carrageenan
- Thickening: Carrageenan increases the viscosity of liquids, contributing to a richer mouthfeel.
- Stabilizing: It prevents ingredients from separating, maintaining a uniform consistency in products like dairy and non-dairy beverages.

- Gelling: It can form gels, which is useful in desserts and some processed foods.
1.2. Regulatory Status of Carrageenan
Carrageenan is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. However, its safety has been debated. The World Health Organization (WHO) and the European Food Safety Authority (EFSA) have also reviewed carrageenan and established acceptable daily intake levels. Despite these approvals, concerns persist regarding potential inflammatory effects, especially from degraded carrageenan.
2. What Types of Foods Commonly Contain Carrageenan?
Carrageenan is used across many food categories. Here’s a detailed look at some of the most common sources:
2.1. Dairy Products
Carrageenan is frequently added to dairy products to improve texture and prevent whey separation.
- Milk: Some flavored milks, like chocolate milk, use carrageenan to maintain a smooth consistency and prevent cocoa particles from settling. Brands like Horizon have been known to use carrageenan in some of their milk products, while others, such as Strafford Organic Creamery, offer carrageenan-free options.
- Cream: Carrageenan is used in both regular and whipped cream to stabilize the emulsion and enhance the texture. For instance, Organic Valley offers cream without carrageenan, whereas some Trader Joe’s cream products might contain it.

3. Why Is Carrageenan Controversial?
Despite its widespread use and GRAS status, carrageenan has faced scrutiny due to potential health concerns.
3.1. Potential Inflammatory Effects
Some studies suggest that carrageenan, particularly degraded carrageenan, may promote inflammation in the digestive system. Joanne K. Tobacman, MD, a researcher at the University of Illinois at Chicago, has published several studies indicating that carrageenan can activate inflammatory pathways in human cells. This inflammation could potentially exacerbate conditions like inflammatory bowel disease (IBD).
3.2. Degraded vs. Undegraded Carrageenan
It’s important to distinguish between degraded and undegraded carrageenan. Degraded carrageenan, also known as poligeenan, has a lower molecular weight and is known to cause inflammation in animal studies. Undegraded carrageenan, the form used in food, is considered safe by regulatory bodies. However, some research suggests that undegraded carrageenan can degrade in the digestive tract, potentially leading to inflammatory effects.
3.3. Gut Health Concerns
Carrageenan may disrupt the balance of gut bacteria, potentially leading to dysbiosis. A healthy gut microbiome is crucial for overall health, and disruptions can lead to various health issues, including digestive problems, immune dysfunction, and even mental health disorders.
