15 Jun 2018 --- The Center for Science in the Public Interest (CSPI) claims in a new report that Quorn’s mycoprotein ingredient has been linked to severe allergic reactions and gastrointestinal symptoms. However, NutritionInsight spoke to a Quorn spokesperson on the issue, who stated that they “challenge the scientific validity” of the claims. The company will, however, update packaging information to flag possible sensitivities that people may have to mycoprotein, which is derived from mold and forms the basis of Quorn's meat-alternative products.
