A new study says lifestyle habits like exercise and diet become more important in midlife, with the first of two major changes in the body’s molecules.
Researchers examined 135,000 types of molecules and microbes from more than 100 adults. They found major shifts in abundance occurred around two ages – roughly 44 and 60.
The peer-reviewed study was published in the journal Nature Aging.
“Changes in molecules related to cardiovascular disease, the metabolism of caffeine, and skin and muscle were observed at both ages,” The Washington Post reported. But in the 40s, changes were more often related to the metabolism of alcohol and fats; in the 60s, they were more related to immune regulation, kidney function, and the metabolism of carbohydrates.
Healthier lifestyles have particular benefits starting in the 40s, the researchers said.
These findings probably make sense to anyone who notices a drop in physical performance – or ability to handle coffee or liquor – in their 40s and 60s.
Scientists say it’s not clear why these molecular changes happen in the 40s and 60s. However, the findings could lead to a greater understanding of how the body ages and which molecules are most directly linked to certain age-related diseases.
Yes, our bodies change as we age. This is all the more reason to move your body and eat responsibly throughout life at any age.
We help men and women over 50 feel better, look better, and age actively- because our life isn’t over as we age; in many ways, it’s just beginning!
