Glucose

Reducing dietary glucose removes a key substrate that cancer depends upon. Pure glucose is assigned a glycemic index of 100. Sucrose has a lower glycemic index than pure glucose because it contains fructose, which is absorbed more slowly. The widely held belief that the brain can only run on glucose is false. Elevated blood glucose levels provide the primary fuel cancer cells consume at an accelerated rate. Glucose is the form of sugar that circulates in the bloodstream after carbohydrate digestion and absorption. Cancer's extreme glucose demand is central to understanding both how cancer thrives and how it can be starved. The article claims cancer cells consume much more glucose than other cells. Glucose-induced neuronal damage creates a self-reinforcing cycle where neurons lose the ability to use their primary fuel and starve of ATP. High blood sugar destroys the small capillaries that supply blood to neural tissue, driving all forms of diabetic neuropathy. Chronic exposure to high glucose is directly neurotoxic, causing oxidative damage that impairs neurons' ability to absorb glucose. Without fasting or ketosis, astrocytes struggle to deliver fuel to neurons, worsening every gl…
