In the EU: the register of health claims
Claim not authorised in the EU
- Claims for indigestible dextrin (trade name Fibersol-2) of "reduces the rise in blood sugar after meals," "triglycerides after meals," and "bowel movements" were not authorised, because EFSA found the effect not substantiated (2011 opinion).
In the EU, only health claims whose evidence has been assessed by the European Food Safety Authority (EFSA) and authorised by the European Commission may be used on food. “Not authorised” means the evidence for that claim was not established under EU standards — not that the ingredient is dangerous.
