Postprandial glucose

Postprandial glucose refers to blood glucose levels after a meal, often peaking around 60 minutes (typically within 1 to 2 hours) before returning toward fasting baseline. The size and duration of the spike reflect carbohydrate quantity and quality, gastric emptying, insulin response, and tissue uptake. Recurrent large excursions (a value rarely exceeded in non-diabetics is roughly 140 mg/dL) are associated, in a graded fashion, with vascular risk and cardiovascular disease, making postprandial control a key target in metabolic and longevity-oriented nutrition.
