Extracted from seaweeds, carageenan is widely used in the food industry for its stabilizing and thickening properties. It is most often used in dairy and meat products, and is also found in products like soy ice cream and almond milk.
In Europe, carageenan is banned from use in baby foods. In North America, it is widely used in organic foods like juices, chocolate milk, almond milk and baby formulas. Research has shown that carageenan can trigger colitis-like symptoms and promote tumor growth. It has an inflammatory effect in the body - especially in the bowels. Chronic inflammation in the body has been linked to many serious diseases, including, but not limited to, Parkinson's, Alzheimers, heart disease and cancers. Diabetes and glucose intolerance may also be aggravated or triggered by carageenan.
Long story short, read the label on all of your foods and avoid products containing carageenan whenever possible.
