1. Charakterystyka żywności / składnika
The food that is subject of the health claim is partially hydrolysed guar gum (PHGG), which is produced from guar gum by digestion with D-mannanase. It has a lower viscosity and a molecular weight of 20 kDa. PHGG is not naturally occurring in foods and is usually consumed in the form of food supplements. PHGG can be measured in foods by established methods.
The Panel considers that the food constituent, partially hydrolysed guar gum, which is the subject of the health claims is sufficiently characterised.
2.6. Utrzymanie prawidłowego stężenia glukozy we krwi (ID 792)
The claimed effect is “energy and vitality”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings, the Panel assumes that the claimed effect refers to the long- term maintenance or achievement of normal blood glucose concentrations.
The Panel considers that long-term maintenance of normal blood glucose concentrations is a beneficial physiological effect.
3.6. Utrzymanie prawidłowego stężenia glukozy we krwi (ID 792)
A total of eight publications were cited in relation to the proposed claim. The references provided include intervention studies and reviews on the health effects of dietary fibre in general, on the health effects of specific fibres other than PHGG (e.g. guar gum) and on the health effects of foods with a low glycaemic index. The Panel considers that no conclusions can be drawn from these references for the substantiation of the claim. The text of one article was only available in Chinese (Gu et al., 2003) and the English translation was not available to the Panel.
Only two of the studies cited examined the effects of PHGG on blood glucose concentrations. However, both studies (Golay et al., 1995; Trinidad et al., 2004) investigated the effects of PHGG on post-prandial glycaemic responses, and no measures of long-term blood glucose control were reported. The Panel considers that no scientific conclusions can be drawn from these studies in relation to the long-term maintenance or achievement of normal blood glucose concentrations.
The Panel concludes that a cause and effect relationship has not been established between the consumption of PHGG and the long-term maintenance of normal blood glucose concentrations.
