How are Glukose and longevity related?

The relationship between glucose and longevity is multifaceted. Chronically elevated blood glucose accelerates aging through the formation of Advanced Glycation End Products (AGEs), which damage proteins and tissues. Impaired glucose tolerance is a hallmark of metabolic syndrome and type 2 diabetes, both linked to reduced lifespan. Conversely, caloric restriction, which lowers glucose levels, extends lifespan in animal models. In humans, observational studies associate lower fasting glucose with healthier aging, but causal evidence is limited. Consumer DNA or microbiome tests (e.g., from MyBody-X) can identify genetic variants in pathways like insulin signaling or gut bacteria composition that influence glucose metabolism, but they cannot directly predict longevity or prescribe effective supplements. The evidence for such interventions is mostly mechanistic or marketing-based. Practical advice remains: maintain stable blood sugar through a low-glycemic diet, exercise, and weight management. Be skeptical of claims that a test can unlock longevity through glucose-targeted supplements; the science is not yet robust enough for personalized recommendations.
