Centenarians' blood tests reveal secrets of longevity
By analyzing the lifestyle, nutritional and mental characteristics of people who have lived to an advanced age, scientists have found out how the blood of long-livers differs.A recent study published in the journal GeroScience, on blood tests revealed the general indicators of the state of the body of people who have lived to 100 years. Twelve markers related to inflammation, metabolism, liver and kidney function, and anemia were tested. This is the largest existing study, it involved 44,000 people.
Scientists identified uric acid levels as a marker of inflammation, cholesterol and sugar levels assessing metabolic status, liver markers, iron and creatinine levels related to kidney function, and albumin by blood tests.
The study's findings showed that those who lived to age 100 tended to have lower levels of glucose, creatinine and uric acid. The long-livers had blood sugar levels of 6.5 or less and creatinine levels of 125 or less.
The conclusion: people with low iron levels, very low total cholesterol and high levels of sugar, creatinine and uric acid are least likely to be long-lived.
According to the researchers, there is a link between metabolic health, nutrition and exceptional longevity. How much alcohol a person drinks also plays an important role.
Therefore, especially as we age, it is very important to monitor kidney and liver parameters, as well as glucose and uric acid levels.
