The Truth about the Carrageenan Controversy 

The Truth about the Carrageenan Controversy reviews the confusion surrounding the health risks of the use of a popular stabilizing agent – carrageenan derived from red algae. Used widely in food and natural supplements, we investigate carrageenan’s effectiveness, environmental sustainability, biodegradability, nontoxicity, ease of access, and how low cost of production have popularized its use since the 1980’s. With the more ubiquitous use of carrageenan, researchers and regulatory bodies understandably took a greater interest in understanding the health impacts of carrageenan with some concerns of toxicity. We review evidence to support and caution against use.
