Abstract

We studied seven healthy volunteers before and during acute (PD1) and chronic (PD2) ingestion of 30 g polydextrose (PD)/d. The energy value of PD was assessed after [U-14C]PD was added to the 10-g morning dose of PD during PD1 and at the end of PD2. Thirty-one +/- five percent (mean +/- SD) (PD1) and 29 +/- 4% (PD2) of the dose appeared in breath within 48 h. A small fraction of the ingested radioactivity was recovered in urine (4 +/- 1%) and excreted in flatus (< or = 1%) and in feces as volatile fatty acids (VFAs) (< 1%) and bacteria (3-4%); the remaining radioactivity in stools, 33 +/- 3% (PD1) and 32 +/- 4% (PD2), was assumed to be intact PD. Breath excretion of the label was 49 +/- 5% after intracolonic infusion of [U-14C] acetate. The energy value of PD, calculated by means of Miller and Wolin's stoichiometric equation of colonic fermentation, was similar during PD1 and PD2: 4.0 and 6.1 kJ/g, respectively, when breath 14CO2 and VFA production from PD were used for calculation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
