Scientists may have brought us closer to understanding the secret of extending human life. The key to answering the eternal question, can be stored in the iron levels in the blood.
Researchers at Edinburgh University analyzed the data on the duration of life of 1.75 million people, including 60 thousand, lived to the age limit. They found a clear relationship between life expectancy and the level of iron in the blood.
Scientists have discovered that centenarians often have genes that regulate iron levels in the blood. Based on this discovery, mankind may be able to create medicines that control this process, and thanks to them, to prolong human life.
Also according to scientists, their work will fill knowledge gaps on the links between disease, diet and life expectancy.
“We are very excited about the data obtained, as they very clearly indicate that high levels of iron in the blood, reduces healthy life expectancy, and the control of this level will prevent the irreversible age-related changes. According to our assumptions, insights on iron metabolism can lead to understanding why the inclusion in the diet of red meat, rich in iron, can lead to age-related diseases like heart failure, ” said one of the study’s authors Paul Timmers
It was necessary to feed the scientists “resurrected” bacteria, aged in 100 million years
However, he warned that time recommendations for diet and development of advanced methods of treatment is still controversial, as it goes far beyond this work.
However, in the future it might help to figure out why some people have higher life expectancy and will help others extend their lives.
