Type 1 diabetes occurs when the body’s immune system mistakenly attacks itself and destroys beta cells in the pancreas. Beta cells normally produce insulin, a hormone that helps the body turn sugar from food sources into energy for cells throughout the body. But when the immune attack destroys the beta cells, insulin is no longer produced and the sugar stays in the blood where it can cause serious damage to body organs. Because of this, people with type 1 diabetes have to regularly inject insulin in order to stay alive.
Type 2 diabetes is by far the most common form (around 90% of all cases) and the one which is increasing the most. It primarily affects overweight people in middle age or later. It’s not uncommon for the affected person to also have a high blood pressure and an abnormal lipid profile. Gestational diabetes is a temporary special case of type 2 diabetes.
Low glycemic index foods also may be helpful. The glycemic index is a measure of how quickly a food causes a rise in your blood sugar. Foods with a high glycemic index raise your blood sugar quickly. Low glycemic index foods may help you achieve a more stable blood sugar. Foods with a low glycemic index typically are foods that are higher in fiber.
"You only need 10 percent of your beta cells to supply sufficient insulin," Roep said. He said there have been a couple of rare cases where a patient had typical type 1 diabetes but could go through long periods without insulin injections. "Insulin needs can be a moving target, and if you have a lifestyle change it's very plausible that you have a lesser need for insulin, and you can deal with [diabetes] with the beta cells you have," Roep said.
The above two rules are the only dietary rules you need to maintain ideal weight for the rest of your life, assuming you apply common sense and avoid extremes. The diet works by building in regular periods of insulin relief, keeping your body from becoming resistant to insulin. Following these two rules, you will maintain your weight and health by never entering the vicious cycle of increasing insulin resistance.
