Studies Suggest People With A Certain Blood Type May Have A Greater Chance Of Reaching 100
What a Major Swedish Study Reveals About Centenarians

A groundbreaking look at nearly 44,000 people in Sweden followed participants over decades and zeroed in on who actually reached 100. The findings didn’t focus solely on blood type. Instead, researchers discovered that centenarians often shared remarkably stable blood markers starting as early as age 65.
This study, published in recent years, tracked glucose, creatinine, and uric acid levels – three everyday measurements your doctor already checks. People who lived the longest tended to have lower readings in these areas over time. The results point to a pattern: steady, healthy blood chemistry may support the body’s resilience as the years add up.
But here’s the part that surprises most readers…
The Key Blood Markers That Matter Most for a Longer Life

It turns out your blood type might set the stage, but these three markers appear to play the starring role in the longevity story. Researchers noticed that centenarians kept their levels in a favorable range for decades. Lower glucose helps protect against energy swings that stress the body. Stable creatinine reflects smoother kidney function, while balanced uric acid keeps inflammation in check.
Why these markers make such a difference:
- Glucose: Steady levels support steady energy and reduce wear on blood vessels.
- Creatinine: Lower readings often signal kidneys working efficiently over time.
- Uric acid: Balanced amounts may mean less oxidative stress as you age.
The Swedish data showed these markers stayed favorable from the mid-60s onward for those who made it to 100. Blood type O showed up more often in some longevity groups, but the consistent markers were the common thread across all types.
Why Lifestyle Still Matters More Than Blood Type Alone
Here’s the empowering news: while you can’t change your blood type, you have tremendous influence over those key blood markers through everyday habits. Experts agree that lifestyle choices often outweigh genetic factors when it comes to reaching a healthy old age. Small, consistent actions can help keep glucose, creatinine, and uric acid in check.
Actionable tips you can start today to support healthier blood markers:
- Schedule regular check-ups so your doctor can track glucose, creatinine, and uric acid levels early.
- Fill half your plate with colorful vegetables and fiber-rich foods to help maintain steady blood sugar.
- Stay active with 30 minutes of walking most days – movement supports kidney health and reduces stress on your system.
- Choose water or herbal teas over sugary drinks to avoid unnecessary spikes in glucose.
- Manage stress through simple breathing exercises or hobbies, since chronic tension can affect uric acid balance.
These steps don’t promise miracles, but research consistently shows they help many people maintain the kind of stable markers seen in long-lived individuals.
