Outcome Measures
Primary Outcomes (1)
Hemodynamic changes
Hemodynamic changes elicited by stress will be assessed by means of systemic vascular resistance calculated as (blood flow):(mean arterial pressure, and expressed in arbitrary units
Differences observed between 90-min baseline and stress (30-min mental stress and 3-min cold pressure test)
Secondary Outcomes (4)
Changes in concentration of blood glucose
Blood samples will be collected 30, 60, 75, 85, 95, 100, 110, 120, 125, 135, 145, 153, 158, and 163 minutes after the beginning of the test
Changes in concentration of blood insulin
Blood samples will be collected 30, 60, 75, 85, 95, 100, 110, 120, 125, 135, 145, 153, 158, and 163 minutes after the beginning of the test
Changes in blood non-esterified fatty acid concentration
Blood samples will be collected 30, 60, 75, 85, 95, 100, 110, 120, 125, 135, 145, 153, 158, and 163 minutes after the beginning of the tes
Metabolic changes
Differences observed between 90-min baseline and stress (30-min mental stress and 3-min cold pressure test)

Interventions
From t=60 to the end of the metabolic test, volunteers will ingest 7 beverages containing non nutritive sweeteners (25 mL / beverage) every 15 minutes after 10-sec mouth rinsing.
From t=60 to the end of the metabolic test, volunteers will ingest 7 beverages containing sugar (25 mL / beverage) every 15 minutes after 10-sec mouth rinsing.
From t=60 to the end of the metabolic test, volunteers will ingest 7 water beverages (25 mL / beverage) every 15 minutes after 10-sec mouth rinsing.
