Selective effects of nutrients on gut sensitivity and reflexes

Abstract

The effects of intestinal nutrients on gastric tone are more potent than those on gastric sensation, and both depend on the caloric load and the type of nutrient.

Relation between cognitive and hedonic responses to a meal

“…Indeed, the three meals differed for other sensory items apart from palatability, and in other aspects, including volume, caloric content, physical components, and nutrient composition. The contribution of these factors, particularly the nutrient composition, to the cognitive and hedonic responses is incompletely understood . Furthermore, other factors, such as food liking and wanting, that were not controlled in our study, could also play an important role.…”

Mechanisms of postprandial abdominal bloating and distension in functional dyspepsia

“…During fasting, the stomach normally exerts a tonic contraction due to sustained vagal cholinergic input,33 and ingestion of a meal normally produces metered gastric relaxation to accommodate the volume load without a further increase in wall tension 28 34 35. In patients with functional dyspepsia, gastric capacity and compliance during fasting are similar to those in healthy subjects 19 24 25.…”

Effect of Duodenal Glucose and Acute Hyperglycemia on Rectal Perception and Compliance in Response to Tension-controlled Rectal Distension in Healthy Humans

“…With this device, pre-defined tension levels can be applied to a tubular organ wall like the rectal wall, and the methodology had been previously validated in distension studies of the stomach, duodenum, and rectum in humans [16,18,[23][24][25][26][27]. One advantage of the tensostat is, Fig.…”
