EFFECT OF EGG CONSUMPTION IN HEALTHY-VOLUNTEERS - INFLUENCE OF YOLK, WHITE OR WHOLE-EGG ON GASTRIC-EMPTYING AND ON GLYCEMIC AND HORMONAL RESPONSES

The effects of the ingestion of 2 whole eggs (E), 2 egg whites, 2 egg yolks (Y), or no eggs with a standard breakfast on gastric emptying, g lycemic and hormonal responses have been studied in 12 healthy young m ales. E and Y induce a significant delay of gastric emptying, together with reduced blood glucose and insulin peaks (Y). Egg ingestion, what ever the part, increases gastric inhibitory peptide level in blood. Ch olecystokinin is enhanced after E or Y ingestion. The results indicate that egg ingestion, especially yolk ingestion, may be of interest in regulating metabolic variables of glucose metabolism.
