The document lists various vegetables and their total carbohydrate, fiber, and net carbohydrate content per 100 grams. It shows that vegetables contain varying amounts of carbohydrates, from under 1 gram to over 38 grams per 100 grams. The fiber content also varies widely between vegetables, with some like garlic containing over 2 grams of fiber per 100 grams, while others like watercress contain just 0.5 grams. Subtracting the fiber from the total carbohydrates gives the net carbohydrate amount, which is a measure of the impact of the food on blood sugar levels.
