ABSTRACT
Glucose or glucose derived products are increased in blood during the postprandial phase and are, to a certain extent, related to meal composition. Glucose and glucose derived products such as advanced glycation end products (AGEs) can be formed in the intracellular compartment but can also be absorbed as AGEs or AGE precursors present in food. Glucose, glucose metabolites and AGEs alter endothelial cell functions, induce adhesion molecule overexpression (ICAM-1, VCAM), cytokine release (IL-6, MCP-1) and tissue factor production. Tumor necrosis factor alpha systemic level is increased during the postprandial phase as are augmented C reactive protein and fibrinogen level. Hyperglycemia induced an increase in plasminogen activator inhibitor, and shortened fibrinogen half life. Hyperglycemia and AGEs provoked an oxidant stress. The formation of reactive oxygen intermediates perturbates NO (Nitric oxide) formation and are deleterious for cell functions. All the modifications observed in the postprandial phase are not too deleterious but their iterative characteristics may lead to vascular dysfunction.
