Non-starchy VegetablesMost non-starchy vegetables aren't tested because a person would have to eat so much to get 50 grams of carbohydrate for the test (for example, 20 cups of broccoli). And, in fact, for many of these vegetables there is so little carbohydrate encased in so much cellulose that they probably cause little or no rise in blood sugar. For this reason, some low carb diets call these "free" foods. On the other hand, some non-starchy vegetables have more sugar than others, and some, like tomatoes, are actually fruits that will definitely cause a blood sugar rise.
