And just a few months ago the journal Pediatrics reported that teenage boys ate nearly twice as much after a high G.I. meal than after a low one. The really shocking results of glycemic index studies are what foods produce the highest glycemic response. They include many of the starchy foods we eat a lot of, including most bread, most breakfast cereals, and baked potatoes. Table sugar long believed to be the worst thing for people with diabetes isn t as high on the index. Low glycemic foods include pasta, oats, barley, beans, and some varieties of rice.
Acidic fruits have low glycemic indexes.
Not by food analysis. One of the problems with the glycemic index is that it s so difficult to figure out the glycemic index of a food. It s not something that anyone could predict. Consequently, the food scientists simply have to test the responses of real people to real food. Each of the test subjects gets the same amount of white bread, which is the benchmark, and of the test food.
