Why the Postprandial Blood Sugar Should Be Below 155.

Introduction

Studies have shown that an after-meal or postprandial blood sugar leads to a lower all-cause mortality, lower risk of cardiovascular diseases, type 2 diabetes, obesity, renal failure, cancer, etc. Maintaining postprandial blood sugar below 155 mg/dL also leads to a lower HbA1c.

Postprandial sugars are a better predictor of heart attacks and strokes than fasting blood sugar and HbA1c.
