Could your blood type play a role in how well you age? While lifestyle choices certainly matter, a recent study suggests that your blood type might influence how well your body ages over time. Specifically, those with blood type B appear to experience less biological aging compared to other blood types, potentially unlocking insights into the link between longevity and blood type.
A Surprising Connection Between Blood Type and Longevity
The idea that blood group could influence lifespan isn’t entirely new. Back in 2004, a study in Tokyo examined the blood types of 269 centenarians. Researchers found an unexpected trend: people with blood type B were overrepresented among those living to 100 or older. This observation raised the possibility that blood type B might correlate with exceptional longevity.
Fast forward to 2024, and a new study has taken this theory further. It involved more than 5,000 participants and focused on the biological age of 11 key organs. Researchers measured the levels of over 4,000 proteins circulating in the blood to assess the aging process. Their findings were striking—approximately 20% of the participants showed accelerated aging in at least one organ. However, those with blood type B seemed to be immune to this phenomenon.

Why Blood Type B Might Help Protect Against Aging
So, what’s behind the apparent resilience of people with blood type B? Scientists speculate that it has something to do with how their bodies manage metabolic stress and regenerate cells. People with blood type B have the B antigen on the surface of their red blood cells, which triggers the production of antibodies in response to the A antigen. This reaction might help them better handle stressors that could otherwise accelerate aging or cause organ damage.
Though this mechanism is promising, researchers caution that more studies are needed to fully confirm the relationship between blood type B and longevity. It’s clear, however, that these initial findings could change how we think about aging and the role genetics play in the process.
Is Your Blood Type Secretly Sabotaging Your Longevity?
While these findings may sound intriguing, it’s important to remember that blood type B is relatively rare. In fact, only about 7% of the population in France has this blood type. And even if you don’t belong to this group, the overall picture of health and longevity is much more complex. Experts remind us that no single factor, including blood classification, can determine a person’s health.
Factors such as genetics, lifestyle choices, and regular medical check-ups are far more influential when it comes to maintaining good health throughout life. Eating a balanced diet, managing stress, staying active, and having routine health screenings are the cornerstones of longevity, regardless of your blood group.
