The European Food Safety Agency has recently published an opinion on the substantiation of a health claim on beta-glucans from oats and/or barley and the reduction of blood-glucose rise after consumption. This health claim has been submitted by Nestlé S.A. pursuant to article 13(5) of Regulation (EC) No 1924/2006.
The claimed effect was the reduction in blood glucose response after the consumption of 1.3 g of beta-glucan from oats and/or barley in ready-to-eat breakfast cereals manufactured by pressure cooking. EFSA recognized that one human study demonstrated the efficacy of beta-glucans under the proposed conditions of use for the reduction in post-prandial glycaemic response, without affecting significantly insulin responses. EFSA also indicated that the effects of beta-glucans in reducing post-prandial blood glucose responses was well-established.
However, despite this, EFSA concluded that evidences were insufficient to establish the effects of beta-glucans under the proposed conditions of use.
