Good Lifestyle

For years, scientists have tried to understand the secrets of longevity: how do some people manage to live a long and healthy life, while others die young? A group of researchers claims to know the answer. According to a new study, the clues are in our blood.

Swedish researchers have found that people who live at 100 have lower levels of three compounds in their blood.

The first compound that those who reached their 100th anniversary had lower glucose levels. "Very few centenarians had a level of glucose above 6.5 earlier in life," said the co-author of Dr. Karin Modig, associate professor at the Swedish Institute of Karolinska, written in the conversation on the study, published in Geroscience .

The second compound? Creatine. Modig added that most people who lived at 100 did not have "a creatinine level above 125," she added.

The third blood marker that influenced if someone lived at 100 is uric acid, they maintain. Uric acid has been linked to inflammation. AE0FCC31AE342FD3A1346EBB1F342FCB

As part of the study, researchers collected data from 44,000 people in Sweden who were born between 1893 and 1920, all with health assessments from 64 to 99 years.

The researchers followed the subjects up to 35 years old. Only 1,224 of them (2.7%) lived at 100 years.

They also examined two other compounds. "People in the lower groups out of five for total cholesterol and iron levels had a lower chance of reaching 100 years compared to those with higher levels," Modig wrote.

"It is reasonable to think that factors such as nutrition and alcohol consumption play a role," added Modig. "Keeping a trace of your renal and hepatic values, as well as glucose and uric acid as they get older, is probably not a bad idea."

Modig admitted that longevity also has to do with luck. "Chance probably plays a role at some point in reaching an exceptional age," she wrote.

"But the fact that the differences in biomarkers can be observed for a long time before death suggests that genes and lifestyle can also play a role."
