Carrageenan is a food additive derived from seaweed that is commonly used in a wide range of processed foods as a thickener, stabilizer, or emulsifier. It does not contain gluten, as it is not derived from gluten-containing grains like wheat, barley, or rye. Therefore, carrageenan is considered gluten-free and is often included in gluten-free diets. carrageenan has been used for centuries in traditional Irish cuisine and is generally recognized as safe for consumption by regulatory bodies, including the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, some individuals may still experience gastrointestinal symptoms after consuming carrageenan-containing products, and it is always advisable to consult with a healthcare professional if you have any concerns about carrageenan consumption.
