Scientific Opinion on the substantiation of a health claim related to Yestimun^® and defence against pathogens in the upper respiratory tract pursuant to Article 13(5) of Regulation (EC) No 1924/2006

Abstract

Following an application from Leiber GmbH, submitted for authorisation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006 via the Competent Authority of Germany, the Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to Yestimun® and defence against pathogens in the upper respiratory tract. The food that is the subject of the health claim, Yestimun®, which consists of (1,3)-(1,6)-β-D-glucans from brewer’s yeast cell wall, is sufficiently characterised. The claimed effect, defence against pathogens in the upper respiratory tract, is a beneficial physiological effect. No human intervention studies from which conclusions could be drawn for the scientific substantiation of the claim were provided by the applicant. The Panel concludes that a cause and effect relationship has not been established between the consumption of Yestimun® ((1,3)-(1,6)-β-D-glucans from brewer’s yeast cell wall) and defence against pathogens in the upper respiratory tract.
