A Swedish study that followed more than 44,000 people for 35 years reveals a crucial finding: exceptional longevity depends not on extreme blood test results, but on maintaining a sustained biochemical balance. Researchers identified that those who reached 100 years of age had, for decades prior, moderate levels in 10 key markers. This pattern suggests that the real key lies not in individually optimizing each value, but in cultivating an overall state of metabolic homeostasis.
The centenarians consistently showed lower levels of glucose, creatinine, and uric acid, along with balanced liver enzymes. Contrary to expectations, they exhibited moderately high levels of total cholesterol and iron, challenging conventional wisdom regarding these parameters. This suggests that in advanced age, the body requires adequate nutritional reserves and that the obsession with reducing certain values to absolute minimums could be counterproductive to longevity.
