Old question, but "Yes."
Not all carbohydrates are equal as far as nutrition goes. Simple carbohydrates contain refined sugars that have no nutritional value and, generally, a high calorie count, such as candy, soda and sweetened desserts. On the other hand, complex carbohydrates provide your diet with nutritional fiber, vitamins and minerals from whole grains and starchy vegetables. The recommended daily allowance of carbohydrates is 130 grams for both men and women. One cup of cubed butternut squash contains more than 16 grams of complex carbohydrates.
