Optimal Postprandial to Preprandial Glucose Difference in Non-Diabetics

There is no specific optimal postprandial to preprandial glucose difference mentioned in the provided studies. However, the studies suggest that:

• Higher consumption of carbohydrate-rich and deep-fried foods is associated with higher postprandial glucose levels 1
• Longer postprandial light-intensity physical activity and moderate-to-vigorous-intensity physical activity are associated with lower postprandial glucose levels 1
• Consuming less refined grains and more protein-rich foods, getting more physical activity, and having a longer sleep duration are associated with lower postprandial glucose levels in Asian adults without diabetes 1
• The postprandial glycemic response in women is different from that of men, and carbohydrates are the main determinant of elevated postprandial glucose levels 2

Key Findings

• The studies focus on the factors that influence postprandial glucose levels, such as diet, physical activity, and sleep, rather than providing a specific optimal postprandial to preprandial glucose difference 3, 1, 2
• The use of continuous glucose monitors (CGMs) can detect diet-induced differences in estimated plasma glucose concentrations in healthy, non-diabetic adults 3
• Postprandial hyperglycemia is more strongly linked to an increased risk for cardiovascular events than fasting or preprandial glucose levels 4

Factors Influencing Postprandial Glucose Levels

• Diet: carbohydrate-rich and deep-fried foods, refined grains, protein-rich foods 1, 2
• Physical activity: postprandial light-intensity physical activity, moderate-to-vigorous-intensity physical activity 1
• Sleep: longer sleep duration 1
• Sex: postprandial glycemic response differs between men and women 2
