See more at 4:44 in my video How to Treat Heart Failure and Kidney Failure with Diet. Indeed, rather than trying to genetically engineer a bacterium that eats up trimethylamine or ingesting a gut enzyme from cows and sheep to convert it into methane, simply limiting the consumption of foods rich in choline and carnitine, perhaps specifically L-carnitine, may effectively limit the amount of TMAO circulating in our body. Indeed, studies show that people who don't eat meat, dairy, or eggs can virtually eliminate TMAO from their blood. Do we need to, about high-choline plant foods, like broccoli? Take probiotics.
