Pushing numbers to extremes can backfire. Health often lives in the middle. Your clinician reads lab values in context, including age, medications, diet, and current diseases. However, this population view still offers helpful direction for prevention.
More About Glucose
Glucose reflects how your body manages sugar. In this study, people with glucose values in the highest ranges had lower odds of reaching 100. That finding fits decades of research linking chronic hyperglycemia to vascular and nerve damage. It also aligns with diabetes care targets. The American Diabetes Association lists fasting plasma glucose under 100 mg/dL as normal. It defines 100 to 125 mg/dL as prediabetes, and 126 mg/dL or higher as diabetes. The study did not diagnose diabetes in a clinical way across the full cohort. It instead grouped people by quintiles of measured glucose and then estimated the odds of becoming a centenarian. Sustained high glucose tends to be associated with a higher disease risk. Therefore, aiming for healthy ranges makes sense for long-term health.
