The postprandial situation as a pro-inflammatory condition.

Postprandial lipemia has been associated with cardiovascular disease. The current pathophysiological concept is that postprandial remnant lipoproteins migrate into the subendothelial space and that remnants activate circulating leukocytes and endothelial cells. Activated monocytes adhere to endothelial adhesion molecules, facilitating subendothelial migration of monocytes. These cells differentiate into macrophages, with the risk of foam cell formation, due to uptake of remnants and modified lipoproteins. Evidence is emerging that specific interventions may reduce the atherogenic postprandial inflammation. Fruits rich in polyphenols, virgin olive oil, carotenoids and exercise have recently been found to reduce postprandial inflammation. Pharmaceutical interventions with fibrates or statins not only improve the overall lipid profile, but reduce postprandial inflammation as well. This review will deal with the current concept of postprandial inflammation in relation to the development of atherosclerosis and potential interventions to reduce postprandial inflammation.
