(presseportal.ch)
  • Most studies confirm a circadian rhythm, but there are also variations related to food intake, high ghrelin levels being recorded immediately preprandially and low postprandially, suggesting even that ghrelin is secreted in a pulsatile manner in association with food intake (ghrelin is involved in meal initiation)(27). (medicina-interna.ro)

  • Until its discovery, it was known that the ingestion of fatty acids or medium-chain triglycerides increases the production of active ghrelin(13) without changes in total circulating ghrelin level, indicating that the ingested fatty acids are used for ghrelin acylation (and thus activation)(14,15). (medicina-interna.ro)
