The Glycemic Index and the Nervous System
1:02:30 - 1:20:29 (17:58)
Understanding the relationship between the glycemic index and the nervous system can help us make smarter food choices to satisfy sugar cravings without causing a sharp rise in blood sugar levels, which triggers the release of dopamine and can make us want more sugary foods.

Summary
This episode explores the relationship between the glycemic index and the nervous system, highlighting how sweet foods trigger the release of dopamine and stir neural circuits. The glycemic index is discussed as a tool to manage sugar cravings and reduce the steepness of glycemic load in blood sugar levels, ultimately short-circuiting the neural pathways that lead to sugary food cravings.

Summary
The absolute level of dopamine caused by ingesting sugar is not as high as that caused by smoking crack, but the rate of dopamine increase over time has a profound effect on behavior. Lower glycemic index sweet foods or adjusting them with fiber or fat might be a better option to satisfy sweet cravings.
