Potential adverse health effects of dietary lipid oxidation products

Abstract

Lipid oxidation products (LOPs) are widely present in many lipid- containing foods. They usually enter the gastrointestinal tract from dietary sources and/or are produced in vivo. Part of LOPs were absorbed into the blood and transported into tissues. A growing bulk of evidence suggests that LOPs, mainly reactive aldehydes and oxysterols, are potentially involved in the pathogenesis of many chronic diseases, such as atherosclerosis, Alzheimer’s disease, and inflammatory bowel disease. This review summarizes the current knowledge of the adverse effects, cytotoxicity, and the main mechanisms of LOPs involvement in humans and animals.
