Besides the noodles (made with wheat flour) and the cheese sauce mix, there are some preservatives and other flavoring ingredients like sodium phosphate, silicon dioxide, ferrous sulfate, and citric acid, to name a few. Not all are bad, of course. Hamburger Helper actually removed their "artificial flavors" a while back, which was a nice step. However, the best part about this easy meal (our homemade version, of course) is that you can control exactly what your family is eating.
