In the EU: the register of health claims

EU-authorised claim

  • Two claims are authorised: "beta-glucans help maintain normal blood cholesterol levels" (3 g per day from oats or barley) and "consumption with a meal reduces the blood glucose rise after that meal" (4 g per 30 g of available carbohydrate).
  • The "immune" claim for yeast beta-glucan was not authorised.

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.
