Researchers have made a groundbreaking discovery about aging, suggesting that humans experience two distinct “aging peaks” around the ages of 44 and 60. According to a recent study, these peaks are marked by significant molecular changes in the body.
The study, published in Nature Aging, tracked a group of 108 adults over several years and analyzed their biological samples to identify patterns in aging. The researchers found that certain biomarkers, such as RNA, proteins, lipids, and microbiome taxa, underwent dramatic changes at these two age points.
The mid-40s peak showed significant changes in metabolism related to lipids, caffeine, and alcohol, as well as cardiovascular disease and skin and muscle dysfunctions. In contrast, the early 60s peak was associated with carbohydrate and caffeine metabolism, cardiovascular disease, immune regulation, and kidney function.
Geneticist Michael Snyder notes that these findings suggest there are more significant factors at play than just menopause or perimenopause, which can contribute to changes in women’s bodies around this age. The researchers emphasize the need for further research to better understand how the human body changes over time.
While the study had a relatively small sample size and limited biological samples, it provides valuable insights into the complex process of aging. Future studies could help uncover more about these “aging peaks” and their impact on human health.
