– af European Food Safety Authority (EFSA) (2014)
Following an application from InQpharm Europe Ltd, submitted for authorisation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006 via the Competent Authority of the United Kingdom, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to a standardised aqueous extract from white kidney bean (Phaseolus vulgaris L.) and reduction of body weight.
The Panel considers that the food is sufficiently characterised. A reduction in body weight is a beneficial physiological effect for overweight individuals. The applicant identified a total of four human intervention studies which investigated the effects of the aqueous extract from white kidney bean on body weight as being pertinent to the claim. No conclusions could be drawn from two of these four studies. In weighing the evidence, the Panel took into account that one human intervention study showed an effect of the standardised aqueous extract from white kidney bean in reducing body weight when consumed for 12 weeks, that the reduction in body weight was mostly through a reduction in body fat and that the effect of the standardised aqueous extract from white kidney bean on body weight was supported by a second study of shorter duration. However, the Panel also took into account that the first study was at risk of bias, that the supportive study suffered from methodological limitations and that no evidence was provided for a mechanism by which the standardised aqueous extract from white kidney bean could exert the claimed effect.
The Panel concludes that the evidence provided is insufficient to establish a cause and effect relationship between the consumption of the standardised aqueous extract from white kidney bean (Phaseolus vulgaris L.) and reduction of body weight.
