• Lead Sponsor: Ospedale San Donato

Brief Summary

This study aims at assessing the effects of glucose and different types of breakfast on metabolic and neurofunctional responses in healthy individuals.

Twelve healthy subjects, on a stable diet, in a randomized-crossover fashion, received either a 50 g glucose load (control) or one of these breakfast:

B1: milk (125ml) and cereals (30g); B2: milk (220ml), apple (200g) and cream chocolate filled sponge cake (30g); B3: milk (125ml), bread (50g), apple (150g) and hazelnut cream chocolate (15g). Prior and upon completion of each tolerance test, an EEG was performed to measure frontal P300-evoked potentials.

Primary Outcome Measures

Name	Time	Method
Effect of glucose vs different kind of breakfasts on cognitive performances via brain evoked-potentials measure	The incremental (post-pre) frontal P300 potential was assessed as a "change" ( before and 180 min after consumption)	On the same morning of the glucose tolerance test, before and 180 min after consumption, an EEG was performed to record P300 wave-evoked potentials.

Secondary Outcome Measures

Name	Time	Method
Effect of glucose vs different kind of breakfasts on AUC_glycemia in healthy subjects	Blood samples are drawn at -15, 0, 15, 30, 45, 60, 75, 90, 120 minutes with respect to the ingestion.	The incremental area under plasma glucose concentration curve (AUC_glycemia) was used as summary measures of the metabolic responses resulting from the intake of either glucose or one of the 3 breakfasts. The incremental AUC was calculated as the difference between the total AUC and the product of the basal, pre-test concentration time during the experiment (i.e., 120 min).
Effect of glucose vs different kind of breakfasts on AUC_ghrelinemia in healthy subjects.	Blood samples are drawn at -15, 0, 15, 30, 45, 60, 75, 90, 120 minutes with respect to the ingestion.	The incremental area under plasma ghrelin concentration curve (AUC_ghrelinemia) was used as summary measures of the metabolic responses resulting from the intake of either glucose or one of the 3 breakfasts. The incremental AUC was calculated as the difference between the total AUC and the product of the basal, pre-test concentration time during the experiment (i.e., 120 min).
Effect of glucose vs different kind of breakfasts on AUC_insulinemia in healthy subjects.	Blood samples are drawn at -15, 0, 15, 30, 45, 60, 75, 90, 120 minutes with respect to the ingestion.	The incremental area under plasma insulim concentration curve (AUC_insulinemia) was used as summary measures of the metabolic responses resulting from the intake of either glucose or one of the 3 breakfasts. The incremental AUC was calculated as the difference between the total AUC and the product of the basal, pre-test concentration time during the experiment (i.e., 120 min).
