Higher plasma levels of the gut microbiome-derived metabolite Trimethylamine-N-oxide (TMAO) are associated with a significantly higher risk of incident atherosclerotic cardiovascular disease (ASCVD) in a diverse, community-based population free of prior cardiovascular disease.

This study suggests that higher levels of TMAO, a byproduct of gut bacteria processing nutrients like red meat and eggs, are linked to a higher risk of heart disease. While it doesn't tell you to eliminate these foods, it highlights the importance of your gut health and kidney function. If you have risk factors for heart disease, discussing your diet and TMAO levels with your doctor might be worthwhile, especially if you have reduced kidney function.
