Eight vegetables appear on the Harvard Medical School list, including green peas, parsnips, carrots, yams and potatoes. Of these vegetables, carrots have the lowest glycemic index number at 35. Comparatively, a baked russet potato averages a glycemic index value of 111. Glucose has a glycemic index value of 100. Foods with lower glycemic index numbers affect your blood sugar and insulin levels less than foods with higher glycemic index values.

Most nonstarchy vegetables do not have glycemic index values because they would have to be consumed in very large quantities to affect a person's blood sugar levels. Starchy vegetables on the About.com list include beets, rutabagas and corn. Butter beans, kidney beans, navy beans and soy beans represent some of the legumes on the list. Glycemic index values for legumes ranges from 14 to 59.

Search the glycemic index by food name on the University of Sidney's glycemic index page at GlycemicIndex.com. For example, seven different versions of carrots appear on the list including boiled, raw, ground, diced and carrot paste. An 80-gram serving of carrots ranges from 16 to 92 for glycemic index values depending on the way carrots are prepared.
