  Purpose

Dietary protein differing by their amino acid composition could modulate undesirable metabolic and functional responses to a meal rich in saturated fat and sugars. This study aims at examining the specific effects of dairy protein with different cysteine contents on the postprandial undesirables effects elicited by the ingestion of a high fat meal in overweight subjects.

Arms Assigned Interventions
Experimental: Casein
Protein source in the high fat meal is casein
Dietary Supplement: Postprandial metabolic and functional measures
After ingestion of a high fat meal containing the different protein sources, the subjects undergo a series of measures of endothelial dysfunction and blood and urine sampling for the assessment of proinflammatory cytokines levels and metabolomics determinations.
Experimental: Milk soluble protein
Protein source in the high fat meal are milk soluble protein
Dietary Supplement: Postprandial metabolic and functional measures
After ingestion of a high fat meal containing the different protein sources, the subjects undergo a series of measures of endothelial dysfunction and blood and urine sampling for the assessment of proinflammatory cytokines levels and metabolomics determinations.
Experimental: Alpha lactalbumin
Protein source in the high fat meal is alpha-lactalbumin
Dietary Supplement: Postprandial metabolic and functional measures
After ingestion of a high fat meal containing the different protein sources, the subjects undergo a series of measures of endothelial dysfunction and blood and urine sampling for the assessment of proinflammatory cytokines levels and metabolomics determinations.
