You can "read" from your blood whether someone has a chance to live to be 100 years old.  Latest research

For a long time, humanity has been interested in how long a person can live and what determines it. Now scientists are proving that we can also find out who will be lucky enough to live to be a hundred. How can you find out about this?

Certainly most of us would like to live to be a hundred. There are not that many people around the world who manage to do this. A healthy lifestyle, proper diet and physical activity have a huge impact on this. Is it possible to check who will live to this old age in the future? It turns out that yes. Researchers have shown that it can be “read” from blood by analyzing appropriate parameters.

Who has a chance to become 100 years old?

The largest study, published in the journal “GeroScience”, shows that people over the age of 60 have lower levels of glucose, creatinine and uric acid in their blood compared to their peers, have a high chance of enjoying have an exceptionally long life. The study measured and monitored the levels of various markers in the blood. Thanks to this, scientists were able to determine which people were most likely to live to the age of 100.

A team of scientists from Karolinska Institutet analyzed blood particles collected from 44,500 Swedish citizens. They underwent clinical trials between 1985 and 1996. These people were followed until 2000. The researchers focused on people born between 1893 and 1920. At the time of their first blood collection, these people were between 64 and 99 years old. Then specialists determined which of these people would live to be a hundred. Of the entire group, it was approximately 2.7 percent of the surveyed participants (i.e. 1,224 people). Interestingly, the vast majority (85 percent) of centenarians were women.

Biomarkers associated with the aging process

In a new study, scientists linked 12 biomarkers that influence the condition of our body. In previous studies, specialists have shown that they are related to the aging process or mortality.

During the analysis, it turned out that the biomarker associated with inflammation was uric acid. In turn, biomarkers related to metabolic functions were total cholesterol and glucose. Biomarkers associated with liver function were alanine aminotransferase (Alat), aspartate aminotransferase (Asat), albumin, gamma-glutamyl transferase (GGT), alkaline phosphatase (Alp), and lactate dehydrogenase (LD). Creatinine, in turn, was associated with kidney function, and iron and total iron-binding capacity (TIBC) were associated with anemia. The nutritional biomarker was albumin.

Metabolism, nutrition and longevity

“We found that, overall, people who lived to their 100th birthday tended to have lower levels of glucose, creatinine and uric acid in their 60s. Very few centenarians had a glucose level above 6.5 or a creatinine level above 125 at the beginning of their lives,” said Prof. Karin Modig from Karolinska Institutet.

In some cases, the differences found by researchers were not large, but they still believe they suggest a potential link between metabolism and longevity. The study didn’t make a specific lifestyle recommendation, but it does point to certain factors and biomarkers in the blood that may influence longevity. According to researchers, nutrition and alcohol consumption play a role in reaching your 100th birthday. “Tracking your kidney and liver values, as well as your glucose and uric acid levels, as you age is probably a good idea,” the researcher added.
