1.4. Apple polyphenols (ID 2713)
The food constituent that is the subject of the health claim is “Pyrus malus (common name apple) extract powder containing polyphenols” related to the following claimed effect: post-prandial glycaemic responses.
Polyphenols include a wide range (thousands) of compounds belonging to subgroups of flavanones, flavonols, flavan-3-ols, such as proanthocyanidins, as well as flavonones, isoflavonoids and anthocyanins. Apples typically contain hydroxycinnamic acid derivatives, flavan-3-ols (monomeric and oligomeric), flavonols and their conjugates, and dihydrochalcones such as phlorizin (Shahidi and Naczk, 2004). In addition, anthocyanins are found in the skin of some red apple varieties.
The Panel notes that the nature and amount of different polyphenol compounds in the apple extract powder has not been specified in the information provided.
Two of the three references provided for the scientific substantiation of the claim were a narrative review on the health effects of phlorizin, which included no original data, and one unpublished in vitro study for which only an abstract was available. The third reference reported on a human intervention study on the effects of clear and cloudy apple juices characterised on the basis of their content in single polyphenols (e.g. phlorizin, chlorogenic acids, phloretin xyloglucoside and (+)-catechin) and sugars on post-prandial glycaemic and insulinaemic responses as compared to a control beverage containing the same amount of sugars (Johnston et al., 2002). The Panel notes that the pectin content in the apple juices is not reported, and that therefore none of them are sufficiently characterised with respect to all of the components which could have an impact on the claimed effect (EFSA Panel on Dietetic Products Nutrition and Allergies (NDA), 2010).
The Panel considers that the food constituent, apple polyphenols, which is the subject of the claim, is not sufficiently characterised in relation to the claimed effect considered in this section.
The Panel concludes that a cause and effect relationship cannot be established between the consumption of apple polyphenols and the claimed effect considered in this section.
