Scientists: Blood Iron Levels Strongly Correlated With Long Lifespan

The discovery might explain a link between diet and disease.

Scientists may have just uncovered a new secret to extending the human lifespan: making sure there’s the right amount of iron in our blood.

University of Edinburgh scientists looked at data about 1.75 million people’s lifespans, including 60,000 who lived to reach an unusually old age, and found a clear link between blood iron levels and a longer life, according to research published Thursday in the journal Nature Communications. Specifically, the team found that multiple genes that seem to regulate blood iron levels were often found in long-lived people, and now speculate that they could develop lifespan-extending pharmaceuticals to do the same thing.

Knowledge Gap

The team also thinks their research fills in a knowledge gap that explains the link between lifespan, diet, and disease.

“We are very excited by these findings as they strongly suggest that high levels of iron in the blood reduces our healthy years of life, and keeping these levels in check could prevent age-related damage,” Edinburgh researcher Paul Timmers said in a press release. “We speculate that our findings on iron metabolism might also start to explain why very high levels of iron-rich red meat in the diet has been linked to age-related conditions such as heart disease.”


New Groundwork

Timmers warned, though, that the implications for diet and any potential treatments are speculative for now, and far beyond the scope of this new study.

Even so, the study lays an important groundwork for future attempts to tease out what it is that makes some people live longer — and to find out how everyone else can get a slice of the iron-rich pie.
