Meat is one of the sources of protein that we consume regularly. Until now, there are still some pros and cons regarding the benefits of consuming meat, especially red meat. Some experts consider that meat can contribute well to diet if consumed in reasonable amounts. However, others believe that red meat can increase the risk of heart disease.

According to a recent study conducted by the Cleveland Clinic, consuming red meat as the primary source of protein in a whole month can increase the level of trimethylamine N-oxide (TMAO) in the body. Red meat can increase the performance of intestinal bacteria in producing TMAO. Increased levels of TMAO are known to cause clogged arteries and increase the risk of heart diseases.

In their study, the researchers hired 113 participants who were asked to follow three different diets for four weeks. The first group was the red meat group. Twelve percent of the group’s daily calories came from red meat (pork/beef) without fat. The second group was the white meat group. The participants in this group got their protein from poultry meat. The last group got its protein from legumes, nuts, and isoflavone-free soy products.

After four weeks, the participants were asked to undergo a urine and blood test to measure TMAO levels in their body. The researchers found that participants who underwent a red meat diet had an increase in TMAO levels 3-10 times hgher when compared with other participants. The researchers further explained that TMAO levels would decrease after participants change their diet within four weeks.
