When it comes to controversial yet common food additives, carrageenan leads the pack. While it’s easy to get, fairly inexpensive and adds no taste to products, some have said it causes digestive issues. Consumer activists, including farm policy group Cornucopia Institute and popular blogger “Food Babe” Vani Hari, have fought against use of the ingredient.###Studies published by the University of Chicago and the University of Illinois at Chicago in 2011 and 2012 indicated that carrageenan could cause gastrointestinal inflammation and lead to glucose intolerance, contributing to Tiron gluconate otcype 2 diabetes.
