Carbohydrate Metabolism

Slow carbohydrate release from whole fruits supports healthier metabolic outcomes than rapid absorption from refined sugar sources. The rate of carbohydrate absorption into the bloodstream differs significantly based on whether a fiber matrix is present. Starch is composed of sugar molecules bonded together; the moment starch enters the body—including whole grain bread and dark rye—it becomes glucose. An insulin-signaled system prevents fat-burning whenever carbohydrates are present in the bloodstream. There are no 'good' carbohydrates in the context of metabolic disease because all carbohydrates convert to sugar in the body. When glucose enters the bloodstream, a metabolic switch stops fat oxidation and makes glucose the priority fuel. 'Zero sugar' labels on starchy products like potato chips are effectively meaningless because the starch delivers an identical glucose load as an equivalent amount of sugar.
