Nope. It's not real food. Your body was designed to operate on whole natural foods.
You're getting a lot of unnessary stuff in those processed prepackaged foods and your are likely missing out on some beneficial nutrients by not eating real food. Those protein shakes and bars are fine on occasion, just don't use them ever day.
