The glycemic index shows how much various foods raise blood sugar compared with glucose, the simplest form of sugar, which is given an arbitrary value of 100. Table sugar is 83. Note that some higher index foods, such as potatoes and pumpkin, also come with vitamins, minerals, fiber and other key nutrients.
