“…This modification would not alter the digestibility of soyabean protein. The results in the literature on the effect of an intestinal tube on the gastric emptying of a mixed liquid meal in human subjects are scarce and conflicting, reporting either a slight delay in gastric emptying using an indirect method (Medhus et al 1999) or no effect using a more direct method (Muller-Lissner et al 1982). The latter study also reported no effect of a transpyloric tube on the duodeno -gastric reflux after feeding.…”

Sweet lupin (Lupinus albus), a protein-rich legume devoid of anti-nutritional factors, is considered to have a high potential for protein nutrition in man. Results concerning the nutritional value of lupin protein are, however, conflicting in animals and very scarce in human subjects. Furthermore, where fibre-rich protein sources are concerned, the long-term nutritional results are often obscured, particularly since fibre-promoted colonic fermentation may bias the energy supply and redistribute N flux. We therefore studied, during the postprandial phase, the bioavailability and utilisation of lupin-flour protein in nine healthy men who had ingested a mixed meal containing intrinsically 15N-labelled lupin flour as the protein source (Expt 1). The real ileal digestibility (RID) and ileal endogenous N losses (IENL) were assessed using a perfusion technique at the terminal ileum, and the N content and 15N enrichment of ileal samples. Lupin flour exhibited a high RID of 91 (SD 3)% and low IENL (5-4 (SD 1.3) mmol N/h). Postprandial dietary deamination was also assessed from body dietary urea and urinary dietary N excretion, and compared with results in nine healthy men following an iso-energetic meal containing a 15N-soyabean-protein isolate with a similar RID, as a control (Expt 2). Postprandial dietary deamination was similar after lupin and soyabean meals (17 (SD 2) and 18 (SD 4)% ingested N respectively). We therefore conclude that lupin protein is highly bioavailable, even if included in fibre-rich flour, and that it can be used with the same efficiency as soyabean protein to achieve postprandial protein gain in healthy human subjects.

“…the double sampling intubation technique is now considered to be the most reliable for exercise studies. Some authors, however, have discussed a possible effect of intubation itself (14,20) on CER and recently attempts have been undertaken to study GER non-invasively by applying either ultrasound (8) or stable isotope methods.…”

“…In addition, gastric emptying and intragastric distribution of fat have been examined by either scintigraphy using specific fat markers (7, 8, 10–12) or intubation techniques (5, 10, 13, 14). Both methods suffer from disadvantages, including exposure of the subjects to radiation during scintigraphy and the possible disturbance of normal physiology due to gastrointestinal intubation (15–17), and three‐dimensional assessment is also not possible. Magnetic resonance imaging (MRI) has been used to evaluate the distribution of an oil/water mixture in the human stomach (9).…”

Purpose:To develop an MRI technique to investigate how varying the ingestion order of nonfat and fat components of a solid meal influences three-dimensional intragastric distribution and gastric emptying (GE). Materials and Methods:Eight healthy subjects were studied twice in randomized order. On one occasion (condition F-NF), the fat component (40 g mayonnaise on toast) was served before the nonfat component (270 g pasta, 200 g tomato sauce, 100 mL water); on the other (condition NF-F), the ingestion order was reversed. GE and intragastric distribution of both components were assessed by MRI for 180 minutes.Results: During condition F-NF, GE of fat was significantly faster than during condition NF-F (T 25 [min]: F-NF: 20 Ϯ 9; NF-F: 40 Ϯ 7; P Ͻ 0.05), a larger amount of fat was observed in the antrum during condition F-NF, and more fat layering occurred. No differences were observed in total GE between the two conditions. Conclusion:Meal ingestion order influences GE and intragastric distribution of fat, which can be assessed by MRI techniques, providing new insights into the physiology of gastric processing and intragastric distribution of different meal phases.
