Scientists in the United States and New Zealand have calculated that in addition to the 960,000 diabetes deaths worldwide each year, raised blood sugar levels are linked to 1.5 million deaths from heart disease and 700,000 from strokes.
So far high blood sugar has been linked to cognitive impairment, increased risk of blood clots, diabetes, and numerous other disorders. There's a reason for that: the human body is not designed to run on glucose 100% of the time! High blood sugar means high insulin, both of which damage arteries. Damaged arteries cause cholesterol to be called to the scene to repair the damage. Yet cholesterol gets blamed for arterial damage, which makes as much sense as blaming the ambulance that shows up at the scene of an accident. You simply cannot be healthy eating large amounts of processed grains and sugar. Those foods are alien to your body, distorting the fatty acid profile of your cells and disrupting cellular function.
Step away from the candy bar and put down the low-fat blueberry muffin.
