What’s In the Blood of 90+ Year-Olds That Makes Life Longer?

People who have lived beyond 90 have quite a lot to say, experiences and all. But besides the wise tales, recent scientific studies have dived into this mystery, focusing on their blood composition. Researchers have uncovered surprising differences that could be key to understanding exceptional longevity. So, let’s explore what science has to say about its discoveries.

The Role of Glucose in Longevity

Studies show that people who live beyond 90 often have lower glucose levels throughout their lives. Glucose is what your body uses for energy. High levels can lead to problems like diabetes, speeding up aging. Keeping glucose levels in check might be critical to living a long life.

Creatinine Levels and Kidney Health

Muscles produce waste called creatinine, which kidneys filter out of the blood. People who live longer tend to have lower creatinine levels, which suggests their kidneys are working well. Healthy kidneys help keep the body free of toxins, promoting overall good health and possibly contributing to a longer life.

Uric Acid and Inflammation Control

Centenarians—people who live to be 100 or older—often have lower uric acid levels. This acid is another waste product from specific food breakdowns (alcohol and red meat). Too much of it can lead to gout, a painful joint condition, and other inflammatory problems.

Cholesterol and Heart Health

Cholesterol is a fatty substance that aids in creating certain hormones and performs other functions like building up cell walls. However, too much of it can lead to heart disease. People who live past 90 usually have balanced levels and are less likely to suffer from any heart-related issues.

The Impact of Lifestyle Choices

While scientists examine what’s in the blood, they also recognize that lifestyle choices play a big role in longevity. People who live long often eat a balanced diet with moderate alcohol consumption. These choices likely work hand-in-hand with good blood health.

Gender Differences in Longevity

It’s interesting to note that most people who live past 90 are women. Several factors contribute to this difference. Biologically, women benefit from protective hormones like estrogen, which have been linked to better cardiovascular health and stronger immune responses.

The Importance of Metabolic Health

Metabolic health means how well your body processes food and energy. Those who live longer tend to have a metabolic profile that lowers the risk of chronic diseases. Good metabolic health, like managing glucose and cholesterol levels, is crucial for longevity.

The Genetic Factor

Besides lifestyle and metabolic health, genetics also play a role in determining who lives past 90. Your genes interact with your environment to shape how you age, and some people may have a genetic makeup that protects against aging.

Inflammation and Aging

Chronic inflammation, which is long-term swelling in the body, is a significant factor in aging. The blood of those who live past 90 shows a better ability to keep inflammation under control, which could help prevent diseases like arthritis and Alzheimer’s.

The Future of Longevity Research

The longevity study is evolving rapidly, with researchers increasingly focused on uncovering why some people live much longer than others. The future of longevity research holds promise for significant breakthroughs, particularly identifying and manipulating the biological markers associated with a long and healthy life.
