Digestive, cognitive and hedonic responses to a meal

Abstract

When appropriate conditions are met, the response to a meal includes a hedonic dimension involving pleasant sensation of digestive well-being.

Abdominal accommodation induced by meal ingestion: differential responses to gastric and colonic volume loads

“…In this study, satiation was not specifically measured, and among the choices in the perception questionnaire, subjects reported by‐and‐large pressure/bloating sensation. In a recent study using another test meal, 20 satiation was also scored on a separate scale, and we found that it tightly paralleled pressure/bloating scores (unpublished data). Furthermore, in this study, the responses were similar whether the predominant sensation was pressure/bloating or not.…”

Cognitive and hedonic responses to meal ingestion correlate with changes in circulating metabolites

“…In previous studies, broth ingestion under these conditions induced satiation and satisfaction; however, satiation after the probe meal in the current study had a negative hedonic dimension with decrease in digestive well‐being despite the fact that discomfort was negligible. A similar dissociated response, i.e., satiation and dissatisfaction, was observed in the previous studies with experimental gastric distension inducing fullness sensation . The meal load in the present study was considerably larger than in previous tests with a regular broth serving; however, well‐being already decreased during ingestion.…”

“…Interestingly, changes in the late lipidic response to the meal were related to digestive well‐being and reduced desire of eating a food of choice. Previous studies showed that lipid meals improve mood and that infusion of lipid directly into the small bowel induces pleasant fullness sensation, i.e., satiation associated to digestive well‐being …”

“…Subjects were recruited by public advertising and were non‐obese (body mass index between 18.5 and 30 kg/m 2 ). Absence of current digestive symptoms was verified using a standard abdominal symptom questionnaire (no symptom ≥2 on a 0–10 scale) . The protocol for the study had been previously approved by the Institutional Review Board of the University Hospital Vall d'Hebron, and all participants gave written informed consent.…”

“…We have recently shown that meal ingestion induces cognitive and digestive responses. We further showed that the cognitive response has a hedonic dimension in terms of digestive well‐being, ranging from pleasantness/satisfaction to unpleasantness/dissatisfaction …”
