Researchers at Stanford University have published a study that reveals that body aging is not a smooth process, but describes it as what happens in “rapid exercise.” Researchers looked at specific proteins through blood tests and found that human aging involved three different turning points, the first of which began around the age of 34.
The new study suggests that proteins in the blood can provide clues about a person’s health and show changes, allowing researchers to estimate a person’s age. The study found that the levels of many proteins in the blood change with age – which can lead to, rather than just, the body’s aging process.
The study involved blood from more than 4,200 people aged 18 to 95. Based on an analysis of protein changes, the researchers found that when protein levels experienced significant “abundance changes,” humans experienced multiple “different times” at about 34, 60 and 78, respectively.
Using a formula around these proteins, the researchers say, they can estimate a person’s age with accuracy over a three-year range. The formula cannot point to the existence of exceptional health conditions in times when people who fail edcompared to their younger ones have failed. Similarly, the researchers found that changes in large amounts of protein showed vary by gender.
The findings “strongly support” the difference in aging in men and women, emphasizing the need to include women in clinical trials and taking into account the biological sex of participants as a factor in the study.
In the future, looking at protein levels in the blood may reveal later than expected, the researchers explain, helping doctors intervene in potential developments in health problems such as dementia. Similarly, these findings could help experts develop new ways to slow down aging.
