Carnitine is a nutrient found naturally in red meat, and artificially in energy drinks. Carnitine is an important as it transports fuel into the body's mitochondria allowing energy to be produced. However some bacteria use carnitine as an energy source, therefore consuming large amounts of red meat, and/or energy drinks results in a greater number of these bacteria within the gastrointestinal tract. The synthesis within the bacteria results in a waste product being produced, trimethylamine (TMA). The liver converts this waste product into trimethylamine-N-oxide (TMAO). This is usually excreted within the urine, however in larger quantities TMAO causes an increase in 'bad' cholesterol, which cannot be destroyed by macrophages in the artery. This leads to the build up of plaque which can lead to Atherosclerosis.
It has been found that red meat eaters have higher levels of TMAO than vegetarians and vegans, so there is a definite link between red meat and levels of TMAO. Higher levels of TMAO result in higher risk of Atherosclerosis. Therefore red meat should be eaten less frequently, to reduce the risk of Atherosclerosis and other issues borne from that.
