Unfortunately this rules out a majority of the carbohydrates found on supermarket shelves. Refined and re-fortified grains are grain-based foods like certain breakfast cereals, pastas, and rice products that have been refined such that the naturally occurring fiber, vitamins, and minerals have been removed. Companies then replace the fiber and synthetic versions of the vitamins and minerals that were initially removed. Sometimes (and this is really sneaky) they put everything back in naturally occurring ratios so that they can still claim the food contains ‘whole grains’. My suggestion: Just eat the real unfortified stuff in the first place.
