Relation between cognitive and hedonic responses to a meal

Abstract

The cognitive (satiation, fullness) and hedonic responses (satisfaction) to meals with equivalent levels of palatability, that is, equally likable, are dissociable. The characteristics of meals in terms of satiation and rewarding power could be adapted to specific clinical targets, whether nutritional supplementation or restriction.

Effects of meal palatability on postprandial sensations

“…The conventional two‐course meal induced a response, featuring satiety and fullness, ie homeostatic sensations, associated to digestive well‐being and mood. Previous studies showed that these responses are dissociable and depend on the characteristics of the meal . Both courses of the conventional meal (potato and vanilla creams) had the same physical characteristics and were found palatable.…”

“…Four 10 cm scales graded from −5 to +5 were used to measure: (i) palatability (very bad‐disagreeable/very good‐delicious),(ii) hunger/satiety (extremely hungry/completely satiated), (iii) digestive well‐being (extremely unpleasant sensation/extremely pleasant sensation) and (iv) mood (negative/positive); two additional 10 cm scales graded from 0 (not at all) to 10 (very much) were used to measure: (v) abdominal bloating‐fullness, and (vi) discomfort‐pain. Subjects received standard instructions on how to fill‐out the scales . The palatability scale was only scored once immediately after ingestion of the test meals.…”

“…These homeostatic sensations have a hedonic dimension, ie are associated to changes in digestive well‐being and mood . Both components of the postprandial experience ie homeostatic and hedonic sensations, are dissociable and depend on the characteristics of the meal in such a way that satiety/fullness may have a pleasant or an aversive dimension . Indeed, we have previously shown that equally likable meals, ie with the same level of palatability, but different composition produced distinctively different homeostatic and hedonic postprandial responses.…”
