Atherosclerotic Cardiovascular Diseases (ASCVD) are the most common cause of death worldwide. Among the well-known con¬tributors to atherosclerosis are less common ones, such as trimethylamine oxide (TMAO). This substance is formed from the oxida¬tion of trimethylamine (TMA) with the participation of flavin oxidases in the liver. TMA is produced with the involvement of the intestinal microbiota from foods rich in choline and carnitine. TMAO promotes the production of foam cells, enhances platelet aggregation, affects endothelial inflammation, and promotes atherosclerosis development. However, further research is needed to determine the effect of dietary changes on reducing TMAO levels and thus reducing incident ASCVD.
