Findings from researchers show high blood levels of TMAO (trimethylamine N-oxide) predict future risk of developing chronic kidney disease over time. The findings build on more than a decade of research related to the gut microbiome's role in cardiovascular health and disease, including the adverse effects of TMAO, a byproduct formed by the gut bacteria from nutrients abundant in red meat, eggs and other animal source foods. The large-scale study measured blood levels of TMAO over time in two large NIH populations and followed the kidney function of more than 10,000 U.S. adults with normal kidney function at baseline over...
