Each and every food we eat is changed to glucose in our stomachs and then is transported into the blood stream. Each food is also assigned a glycemic index number which is a measurement of how much the particular food causes a rise in blood sugar levels. In people with a normal blood sugar level insulin produced by the pancreas controls the amount of glucose in the blood.
Glycemic index is way to see which foods someone should eat to keep blood glucose at a steady rate. Consuming high glycemic foods results in a quicker and higher blood sugar rise, which sends signals to the beta cells in the pancreas to push out more insulin. More and more insulin gets secreted and then these high insulin levels drop the blood sugar level and causes hypoglycemia. You get hungry; eat more high glycemic index food and the cycle starts all over again. Foods from the low end of the glycemic index are converted to glucose slower and at a more constant rate which puts a lower demand for insulin on the pancreas. Because your blood sugar level didn’t spike, it won’t fall as far either.
That rapid spiking and dropping of blood glucose levels over long periods of time is thought by some studies to cause issues with the beta cells ability to produce insulin. It is almost as if they get tired out from producing so much insulin and lose their ability or get fatigued and can’t respond to the signals to secrete insulin. Burning out your pancreas is not a good idea.
Modifying your diet to include more low glycemic foods like fruit, non-starchy vegetables, especially green ones and cutting down on the number of cookies and candy bars and a most of the granola bars sold in stores is a good way to get started.
