1. Charakterystyka żywności / składnika

The food constituent that is the subject of the health claims is sugar beet fibre.
The term “sugar beet fibre” includes fibre derived from all plants of the species Beta vulgaris L. Sugar beet fibre contains hemicelluloses (22-32 %), pectins (22-29 %), cellulose (19-28 %), protein (5 %), ash (3 %) and moisture (7 %). The presence of both soluble and insoluble polysaccharides is roughly in a 2:1 ratio (Thibault et al., 2001). The lignin content is low.
The Panel considers that the food constituent, sugar beet fibre, which is the subject of the health claims, is sufficiently characterised in relation to the claimed effects.

The claimed effect is “blood glucose control; glycaemic control, glycaemic response”. The Panel assumes that the target population is individuals wishing to reduce their post-prandial glycaemic responses.
Postprandial glycaemia is interpreted as the elevation of blood glucose concentrations after consumption of a food and/or meal. This function is a normal physiological response which varies in magnitude and duration, and which may be influenced by the chemical and physical nature of the food or meal consumed, as well as by individual factors (Venn and Green, 2007). Decreasing post-prandial glycaemic responses may, for example, be beneficial to individuals with impaired glucose tolerance, as long as post-prandial insulinaemic responses are not disproportionally increased. Impaired glucose tolerance is common in the general population of adults.
The Panel considers that the reduction of post-prandial glycaemic responses (as long as post-prandial insulinaemic responses are not disproportionally increased) may be a beneficial physiological effect.

2.2. Utrzymanie prawidłowego stężenia glukozy we krwi (ID 752)

The claimed effect is “blood glucose control; glycaemic control, glycaemic response”. The Panel assumes that the target population is the general population.
In the context of the proposed wording, the Panel assumes that the claimed effect refers to the maintenance of normal blood glucose concentrations.
The Panel considers that long-term maintenance of normal blood glucose concentrations is a beneficial physiological effect.

The references provided included reviews and book chapters on the effects of dietary fibre in general, as well as human and animal studies on specific dietary fibres other than sugar beet fibre and/or on outcomes other than measures of glycaemic responses or glycaemic control. The latter were references on blood lipid concentrations and lipid metabolism, on plasma levels of pancreatic and gastrointestinal hormones, on bile acid excretions and on glycerol responses. The Panel considers that no conclusions can be drawn from these references for the scientific substantiation of the claimed effect.
Among the references submitted, two human intervention studies investigated the effects of sugar beet fibre on post-prandial blood glucose concentrations (Hagander et al., 1986; 1988).
In a test meal study, standardised breakfasts with or without sugar beet fibre were given in random order to nine (three female, mean age 67 years, mean BMI 29.9 kg/m2) non-insulin-dependent diabetic subjects managed with diet only (Hagander et al., 1986). The standardised breakfasts were comprised of bread, butter, cheese, milk, water and coffee or tea. Sugar beet fibre was added to the baked bread and given additionally in milk. The two breakfasts contained identical amounts of carbohydrates, protein and fat but differed in their content of dietary fibre. The sugar beet fibre breakfast contained 10.8 g of dietary fibre from sugar beet. Both breakfasts contained 4.1 g of dietary fibre from cereals. Blood glucose concentrations were monitored continuously, and insulin and other hormonal responses were determined at regular intervals for 3 h. The incremental area under the glucose curve was significantly (p<0.05) smaller after the test meal including sugar beet fibre compared with the control meal. No differences were found in the incremental areas under the curves for insulin.
In another test meal study, the same test meals as described above were given in random order to eight healthy volunteers (mean age 67.5 years, mean BMI 28.5±4.9 kg/m2) (Hagander et al., 1988). No differences between the two test meals were observed with respect to post-prandial blood glucose responses (i.e. incremental areas under the curve).
In weighing the evidence, the Panel took into account that only two small studies were provided which assessed the effects of sugar beet fibre on post-prandial blood glucose responses, with inconsistent results.
The Panel concludes that a cause and effect relationship has not been established between the consumption of sugar beet fibre and reduction of post-prandial glycaemic responses.
