Stevia Rebaudiana (Sweet Herb of Paraguay): Rebaudioside A, Steviol Glycosides, Zero Glycemic Load, and Insulin Receptor Sensitivity

The Sacred "Sweet Leaf" of the Guaraní

Known in the indigenous Guaraní language of Paraguay and Brazil as Ka\'a He\'ê ("Sweet Herb"), Stevia (Stevia rebaudiana) has been used for centuries to sweeten bitter herbal medicines like Yerba Mate and soothe heartburn.

1. Steviol Glycoside Molecular Chemistry

The intense sweetness (200 to 300 times sweeter than sucrose) is driven by Stevioside and Rebaudioside A:

• Zero Caloric Breakdown: Steviol glycosides pass through the upper gastrointestinal tract undigested and are metabolized by colonic bacteria into inert Steviol, which is excreted via the kidneys without triggering blood glucose or insulin spikes.


• Pancreatic TRPM5 Channel Stimulation: Enhances glucose-dependent insulin secretion exclusively when blood sugar is elevated.
