As the saying goes, “The behavior of a three-year-old foretells their future.”
So, is it possible to predict whether someone can live to be 100 years old?
Believe it or not, scientists have indeed found some clues.

A study published in the “GeroScience” journal shows that if you meet these three conditions by the age of 60, having 100 candles on your birthday cake is not a dream.

1、 How was the study conducted?

Previous studies on centenarians were often small-scale and focused on a selected group, such as the famous centenarian-rich “Blue Zones.”

This study, however, included data from 44,000 people who underwent health assessments between the ages of 64-99 and were followed for 35 years, making it the largest study of its kind to date.

Researchers compared the biomarker characteristics of those who lived to be over 100 with those of shorter-lived peers and studied the link between these characteristics and the chances of becoming a centenarian. The results showed:

1. Out of 44,000 participants, 2.7% (1,224 people) lived to be 100, with the vast majority (85%) being women.
2. Overall, those who lived to 100 tended to have lower levels of blood glucose, creatinine, and uric acid from their 60s.

2、How low should these levels be to indicate potential longevity?

According to the study, very few centenarians had early blood glucose levels above 6.5 mmol/L or creatinine levels above 125µmol/L; those in the lowest uric acid group had a higher chance of living to 100 compared to those in the highest group.

We’re familiar with blood glucose and uric acid, so let’s talk about creatinine.

It is a product of muscle metabolism in the body. If the kidneys’ filtration function is good, most creatinine will be filtered out, leaving only a small amount in the blood. Therefore, blood creatinine concentration can reflect the damage to the glomerular filtration function to some extent.

To know your three longevity potential indicators, pay attention to these values during health check-ups:
Normal fasting blood glucose: 3.9~6.1mmol/L
Normal creatinine levels: 44-133μmol/L
Normal uric acid levels: Men 150-420μmol/L, Women 90-360μmol/L.

3、How to achieve “longevity indicators” through diet?

To control blood glucose, consider a low-GI diet. GI stands for Glycemic Index, which measures the increase in blood glucose levels within 2 hours after eating various foods.

To control uric acid, pay attention to the purine content of your diet. Consuming high-purine foods frequently, such as animal organs, seafood, broth, and soy products, can lead to excessive production of uric acid that cannot be metabolized in time.
