Acrylamide Exposure and Cardiovascular Risk: A Systematic Review

Area of Science:

• Toxicology
• Cardiovascular Health
• Nutritional Science

Background:

• Acrylamide is a food contaminant from high-temperature cooking.
• Dietary intake is the primary exposure source for non-smokers.
• Acrylamide's cardiotoxic effects in humans are not well understood.

Purpose of the Study:

• To evaluate the association between dietary acrylamide exposure and cardiovascular risk.
• To investigate the role of acrylamide metabolites in cardiovascular health.

Main Methods:

• Comprehensive literature search across four databases.
• Inclusion of 28 studies, primarily cross-sectional designs.
• Risk of bias assessment using Joanna Briggs Institute tools.

Main Results:

• Higher acrylamide exposure linked to increased cardiovascular mortality.
• Inverse association between acrylamide and glucose/lipid levels, diabetes, obesity, and metabolic syndrome.
• Glycidamide (metabolite) positively associated with elevated glucose, lipids, blood pressure, and obesity.

Conclusions:

• Acrylamide's cardiovascular effects may be mediated by its metabolite, glycidamide.
• Further research is required to fully understand acrylamide's impact on cardiovascular health.
• Public health efforts should focus on exposure mitigation and awareness.
