Myths vs facts: Glukose and longevity

Glucose is an essential fuel, but chronically elevated levels accelerate aging. Myth: 'Glucose is inherently bad' – Fact: The body, especially the brain, needs glucose. The problem is sustained high blood sugar, which promotes cellular damage via glycation (AGEs) and oxidative stress. Epidemiological studies link high glycemic load to shorter telomeres and increased biological age. However, effects are modest and confounded by overall diet and exercise. Myths like 'all carbs cause aging' or 'fructose is safe' are oversimplified. Evidence is strong for glycemic control as a longevity marker (e.g., HbA1c predicts mortality), but weak for extreme glucose restriction as a universal anti-aging strategy. Practical takeaway: stabilize blood sugar through fiber, protein, and exercise rather than eliminating glucose entirely.
