Assessment of postprandial lipemia: nutritional influences

Recent reports have contributed new information on the influence of the size and spacing of fat-containing meals on processes related to fat digestion and absorption, lymphatic transport, and postprandial responses of plasma lipoproteins. The postabsorptive concentrations of plasma triglycerides and common polymorphisms of apolipoprotein B and apolipoprotein E exert important influences on postprandial lipoprotein responses. Attention to these characteristics of individuals and groups can facilitate interpretation of responses to meals containing different fatty acids and varying amounts of cholesterol. Additional evidence is accumulating that points to disease related abnormalities of postprandial lipoprotein metabolism related to clearance mechanisms for triglyceride-rich lipoproteins and processes related to reverse cholesterol transport.
