Carbs Compared Other root vegetables look low in carbohydrate content compared to yams. One cup of diced Russet potatoes contains just 27 grams carbohydrate, and one cup of white potatoes contains 23.5 grams, about the same amount of carbohydrates as can be found in a serving of red potatoes.

 Sweet potatoes — which many people in the United States consider interchangeable with yams, though they're different vegetables — are also lower in carbohydrates, with about 27 grams of carbohydrates per serving.

Carb-Conscious Diets Because of the high carbohydrate content in yams, people on low- or zero-carb diets may want to avoid this vegetable. Sweet potatoes, Russet potatoes, white potatoes and red potatoes are all less carbohydrate-heavy root vegetable choices.
