EB. 137: What REALLY Causes Glycation (Is Sugar Really the Problem?)

In this episode we discuss:

• Why glucose and fructose are not the primary drivers of AGE formation

• Whether blood sugar spikes cause glycation

• How fats and ketones can cause glycation

• What’s really responsible for glycation in type 2 diabetes

• Whether fructose causes more glycation than glucose
