Type-2 diabetes is a condition that causes problems with insulin within the body. This condition affects millions of Americans and more so in the African-American, Latino and Native American communities, according to the American Diabetic Association. People with type-2 diabetes either do not produce enough insulin or they become insulin resistant. People with diabetes also develop high blood sugar due to the pancreas not producing enough insulin. This is why it is important for diabetics to follow a diet that does not spike glucose levels.
Simple Carbohydrates
Carbohydrates provide energy to the body, with an emphasis on the brain and nervous system, according to MedlinePlus. There are two classes of carbohydrates: simple and complex. Complex carbohydrates are starchy foods such as legumes, starchy vegetables and whole-grains. These foods are high in fiber and work to maintain healthy blood sugar levels. Simple carbohydrates, also known as refined carbohydrates, lack vitamins, minerals and fiber and contribute to high blood glucose after eating them and weight gain. Examples of simple carbohydrates are white flour, white rice and sugar. They may be enriched with vitamins or minerals, but they are still considered simple carbohydrates.
Sugar
Empty-calorie foods such as candy, cookies, bakery goods, soda and sugar can cause spikes in blood glucose levels. According to the American Diabetic Association, eating sugar will not cause type-1 diabetes, and type-2 diabetes is developed from being overweight. However, according to MedlinePlus, sugar falls under the simple carbohydrate category, which can contribute to weight gain and in turn type-2 diabetes. The American Diabetic Association notes that although there is no direct link between sugar intake and the development of diabetes, it is still wise to limit the intake of sugar or refined carbohydrates.
Potatoes
Potatoes are documented in the book "The Origin Diet" as being high on the glycemic index scale. The glycemic index is a ranking system used to rate foods on a scale of 0 to 100 according to the effect they have on blood sugar levels, as stated by the Glycemic Index website. The glycemic index for a baked russet white potato without fat is 94, which means it causes a huge spike in blood glucose levels. On the other hand, sweet potatoes are more acceptable for diabetics and rank 50 on the glycemic index scale.
