Many believe that in order to increase life expectancy, it is necessary to eat right, do sports and give up bad habits. However, scientists have found out that this may not be enough.

It turned out that there is a connection between the level of iron in the blood and longevity.

During the research, experts studied the DNA of people who lived a long and healthy life, as well as those who had various diseases and died at a fairly early age. In the end, scientists came to the conclusion that people with high iron levels may die younger.

"It is well known that iron deficiency can lead to health problems, but we have shown for the first time that for most people, a small reduction in blood iron levels compared to their current level is likely to be beneficial," the study authors said.

They also found that DNA variations that increase blood iron levels from birth increase the likelihood of developing age-related diseases and the risk of premature death. To avoid this, scientists recommend constantly monitoring the amount of iron in the body.
