Proteins are one of the main building blocks of the body. They hold skin, muscles, and bone together. They also perform many functions in cells. And when released into blood, they help cells communicate. In a new study, scientists found that certain proteins in the blood can predict a person’s age and give insight into their health and wellness.
Researchers collected blood plasma samples from more than 4,000 volunteers between the ages of 18 and 95. They compared the levels of nearly 3,000 proteins. They found that a set of about 375 select proteins could predict people’s age within a few years. Those predicted by these proteins to be younger than they were also performed better in mental and physical tests….
