Meal stimulation of cortisol secretion: A protein induced effect
Abstract
Cortisol and ACTH secretion was studied in 52 healthy subjects who were fasted of fed various diets: standard, high fat, high carbohydrate, high protein. Subjects fed high protein diet (4 gm/kg body weight) showed significant increases in cortisol both at 30 and 60 min after the 1200 hr meal and 30 min after the 1600 hr meal. Increases in cortisol, of a smaller magnitude, were also seen after both the 1200 and 1600 hr meals in each of the diets with 1 gm protein/kg body weight (standard, high fat, high carbohydrate). ACTH was significantly increased following the 1200 hr and 1600 hr meals with the high protein diet. We conclude that dietary protein plays an important role in meal stimulated cortisol release.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
