Using the data of approximately 45 thousand people, scientists developed a blood test to assess the biological age of 11 organs. This analysis allows you to determine how each of these organs are healthy or eroded. If the human organ is much larger than its real age, the risk of illness associated with this organ increases. And vice versa: The young immune system and the brain are related to a longer life.
As part of the new study, experts have determined the average level of this protein for the liver or arteries of a 40 -year -old/70 -year -old person using a protein analysis in the blood. In addition, scientists calculated the age difference for the organs of each of the participants.
It turned out that the heart could rapidly increase the risk of atrial fibrillation and heart failure, and accelerated aging of the lungs contributed to the emergence of a chronic obstructive disease of the lungs. This effect was especially strong for the brain. In people with a very old brain, the likelihood of developing Alzheimer’s disease was three times higher, and in people with a very young brain, this risk was just one quarter of normal.
In addition, each old organ is associated with a shorter life, and the more organs you have, the sooner you die. However, while examining young organs that lead a long life, only the immune system and the brain are connected.
In people with a very old brain, the probability of death has been doubled for more than 15 years, and for participants with a very young brain, this risk decreased by 40%. With a very young immune system, this decrease was already 56%.
Fortunately, your lifestyle affects the age of the organs. People who often consumed alcohol or spruce processed meat in people who smoke, organs were faster, regularly eaten sports or fatty fish, organs were generally younger.
