title: Metabolic and endocrine responses to a standard mixed meal. A physiologic study.
abstract: In order to study endocrine and metabolic responses to normal food ingestion, 8 'healthy' subjects received a standard mixed meal which reflected the composition of Western diet (CHO  47%, protein 23%, fat 26%, alcohol 4%), in 20 min. Before and after the meal, in each subject glucose, lactate, FFA, insulin, C-peptide, glucagon and HGH were determined. The results showed that glycemic and insulinemic responses were not very different from those observed after the classical oral glucose tolerance test. Plasma FFA and blood lactate decreased progressively after the meal. Plasma glucagon and HGH showed opposite changes: pancreatic glucagon rose and HGH slightly declined after composite food ingestion.
