Avoiding or limiting the intake of red meat is recommended to avoid heart disease. Now researchers have uncovered how consuming too much red meat can increase our chances of developing cardiovascular disease from changes in gut bacteria.
It's a two-step process
“In omnivores, is the primary human gut microbe involved in the transformation of γBB to TMA/TMAO. Conversely, long-term vegetarians and vegans have very low levels of this microbe in their gut and therefore have minimal to no capacity to convert carnitine into TMAO.”
What the study means for anyone at risk for heart disease is that switching from a diet rich in red meat would change gut bacteria and lower the chances of heart disease and heart attack.
