As we journey through life, our bodies undergo a fascinating array of biological changes, each person experiencing this metamorphosis at a unique pace. For some, aging seems to sprint ahead, raising the specter of age-related illnesses. Meanwhile, others seem to glide through the years, reveling in prolonged periods of robust health and vitality.
This incredible diversity has spurred scientists to delve into groundbreaking therapies that could slow down this biological clock, potentially staving off diseases like heart disease and dementia, which often accompany the passage of time.
Biological vs. chronological
To truly understand your longevity potential, it’s essential to look beyond the simple count of birthdays and delve into your biological age. Unlike your chronological age, which merely marks the passing of time, biological age reflects how your cells are functioning. This metric is crucial because the younger your biological age, the better your health prospects over time.
Testing biological age
One effective way to calculate your biological age is through a DNA methylation test. DNA methylation is a chemical modification that adds a methyl group (a small molecule) to the DNA strand.
As we age, the pattern of these methyl groups changes. Certain areas of the DNA gain or lose methyl groups in a predictable manner. By looking at the methylation patterns in an individual’s DNA, scientists can estimate the biological age of that person’s tissues or cells.
The DNA methylation age might indicate an older or younger biological age depending on various factors like lifestyle, environment, and diseases. This provides insights into an individual’s health and potential longevity.
Influencing biological age
A variety of lifestyle factors can influence these methyl group patterns. By following a healthy liefstyle, you can reset your biological age, promoting more youthful cell metabolism. Conversely, poor health habits can hasten biological aging. In the pursuit of healthy aging, individuals should prioritize lifestyle choices that support overall well-being:
- Regular exercise, including both aerobic and strength training, boosts physical health and combats aging.
- A balanced nutrition plan with whole foods, antioxidants, and essential nutrients supports cellular health.
- Adequate sleep promotes repair and regeneration, potentially reversing biological age.
- Stress-reducing practices like meditation lower chronic stress levels, positively impacting biological age. (See the cover story.)
- Cultivating meaningful relationships and social connections contributes to a longer, healthier life.
- Intermittent fasting can reduce biological age by about two years.
- One study found that taking a time-
released form of calcium alpha-
ketoglutarate reduced biological age by an average of eight years.
By embracing these choices and testing your biological age to see what’s really working, you can age gracefully and enjoy a higher quality of life for years to come.
