Acrolein is a highly reactive toxic aldehyde that can be found in diet and environment. It is associated with various pathological conditions and can induce harmful effects at the cellular level. Polyphenols, found in fruits, vegetables, and herbs, have been shown to protect against acrolein's toxicity by acting as scavengers and regulators. This review discusses the exposure and toxicity of acrolein and the role of polyphenols in mitigating its contamination and health hazards.
Acrolein, a highly reactive toxic aldehyde, is a common dietary and environmental contaminant which can also be generated endogenously. Exposure to acrolein has been positively associated with some pathological conditions, such as atherosclerosis, diabetes mellitus, stroke, and Alzheimer's disease. At the cellular level, acrolein induces various harmful effects, particularly protein adduction and oxidative damages. Polyphenols are a group of secondary plant metabolites ubiquitously presented in fruits, vegetables, and herbs. Recent evidence has gradually solidified the protective role of polyphenols by working as acrolein scavengers and regulator of acrolein toxicities. This was largely attributed to the ability of polyphenols as antioxidants and sacrificial nucleophiles in trapping acrolein. This review discussed the exposure and toxicity of acrolein, summarized the known and anticipated contribution of polyphenols in ameliorating acrolein contamination and its health hazards.
