At 44 as at 60, aging accelerates, according to a study

Some birthdays seem to matter more than others. American researchers have just confirmed that aging is not linear. Their work was published in the journal NatureWednesday, August 14. The feeling of rapidly “aging” is not necessarily only psychological, it can also be read in the body, by measuring in the blood, in the digestive system, or in certain tissues such as the skin, the presence of certain molecules (proteins, enzymes, RNA) or even microbes, or bacteria.

In their study, researchers from Stanford University in the United States followed the results of analyses of 108 volunteers aged 25 to 75 over several years. They established that the concentration of at least 11,000 molecules present in the human body fluctuates with age. Their presence does not evolve in a linear fashion. The analyses show that there are ages when we age more quickly.

Aging is particularly significant at ages 44 and 60. These two ages correspond to faster waves of aging of the skin, muscles, and cardiac system. There is also a weakening of the immune and renal systems from the age of sixty. Concerning our digestive system, our body tolerates alcohol, caffeine, and fats less well from the age of 44.
It also assimilates sugars less well after 60 years, with a risk of developing type 2 diabetes greater from this age.

It’s the same for men and women, although in women, menopause certainly has an impact on aging. This study shows that most of the biological changes related to age are similar. However, it is possible to change this course of faster aging of the body around 44 or 60 years old. These researchers also remind us that the aging processes are not only biological, they are also linked to lifestyle. After 44 years old, and beyond 60 years old, diet and physical exercise count even more than before to stay healthy.
