Understanding Glycemic Load

Simple carbohydrates (like donuts, white bread, and table sugar) are stripped of fiber. This allows your body to digest them almost instantly, causing a rapid spike in blood glucose.

In response, your pancreas dumps insulin to clear the sugar, leaving you feeling exhausted, irritable, and craving more carbs within an hour.

The Fiber Buffer

Complex carbohydrates like Quinoa, Oats, and Sweet Potatoes are bound to insoluble and soluble fibers. This creates a gel-like matrix in your digestive tract, slow-releasing glucose into your bloodstream for hours of stable focus.
