According to an American study, consuming red meat could accelerate the aging of the arteries and thus promote the appearance of certain diseases. Explanations.
a study by the University of Colorado Boulder (United States), a compound found in red meat, could damage the arteries and play a decisive role in increasing the risk of heart disease. These conclusions were published in the review Hypertension, de l’American Heart Association. ” data-reactid=”24″>“We are what we eat”. Once again, this quote proves to be correct.

attack or stroke. “Data-reactid =” 25 “>“Our work shows for the first time that not only this compound directly affects arterial function, it can also help explain the damage to the cardiovascular system that occurs naturally with age”Says Vienna Brunt, first author and postdoctoral researcher in the Department of Integrative Physiology. As the authors explain, intestinal bacteria activate when we eat meat in order to break it down quickly. How it works ? “By metabolizing the amino acids L-carnitine and choline, they produce a metabolic byproduct called trimethylamine, which the liver converts to trimethylamine-N-oxide (TMAO) and sends it through your bloodstream.”, Details the study. Previously, research had already linked high levels of TMAO to the onset of heart attack or stroke.
A compound to block TMAO?
health of 101 elderly people and 22 young adults. They noticed that the levels of TMAO increased with age. ”Adults with higher blood levels of TMAO had significantly worse arterial function and showed greater signs of oxidative stress or tissue damage in the lining of their blood vessels”, Warns the study. Over the course of their work, the researchers found that when the mice received TMAO, their blood vessels quickly aged. The scientist said the 12-month-old mice (the human equivalent of around 35 years old) were more like 27-month-old mice (80 years old in humans) after eating TMAO for several months. “Preliminary data also show that mice with higher levels of TMAO exhibit reduced learning and memory, suggesting that the compound may also play a role in age-related cognitive decline.”, Ensures the study.
