Scientific Opinion on the substantiation of health claims related to isoleucine‐proline‐proline (IPP) and valine‐proline‐proline (VPP) and maintenance of normal blood pressure (ID 661, 1831, 1832, 2891, further assessment) pursuant to Article 13(1) of Regulation (EC) No 1924/2006

2012 EFSA Journal  
Following a request from the European Commission, pursuant to Article 13.1 of Regulation (EC) No 1924 No /2006 , the Panel on Dietetic Products, Nutrition and Allergies was asked to provide a scientific opinion on a health claim related to isoleucine-proline-proline (IPP) and valine-proline-proline (VPP) and maintenance of normal blood pressure. The food constituent that is the subject of the claim, the tripeptides isoleucine-proline-proline (IPP) and valine-proline-proline (VPP), is

The proposed target population is the general population. In weighing the evidence, the Panel took into account that 15 of the human intervention studies provided, of which seven were adequately powered to detect small between-group differences in systolic blood pressure, did not observe an effect of IPP and VPP on systolic blood pressure or diastolic blood pressure; that interpretation of the results from nine out of the ten studies which reported an effect of IPP and VPP on office systolic blood pressure was limited by methodological weaknesses; that the animal and in vitro/ex vivo studies did not provide additional information on the effect of IPP and VPP on blood pressure in humans; and that there is no convincing evidence for a mechanism by which IPP and VPP could exert the claimed effect in humans at the proposed dose. On the basis of the data presented, the Panel concludes that a cause and effect relationship has not been established between the consumption of IPP and VPP and maintenance of normal blood pressure. SUMMARY Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies was asked to provide a scientific opinion on a list of health claims pursuant to Article 13 of Regulation (EC) No 1924 /2006 . The Commission has agreed with EU Member States that a certain number of Article 13 health claims would be eligible for further assessment by EFSA in order to be able to take a final decision on whether or not to include these claims in the list of permitted health claims. This opinion addresses the scientific substantiation of health claims in relation to the tripeptides isoleucine-proline-proline (IPP) and valine-proline-proline (VPP) and maintenance of normal blood pressure. The scientific substantiation is based on the information provided by the Member States in the consolidated list of Article 13 health claims, references that EFSA has received from Member States or directly from stakeholders and the additional information provided by the competent Authority of Germany for further assessment of this claim. The food constituent that is the subject of the health claim is the tripeptides isoleucine-proline-proline (IPP) and valine-proline-proline (VPP). The Panel considers that isoleucine-proline-proline (IPP) and valine-proline-proline (VPP) are sufficiently characterised.
