I think that over time most of us in this for the life-long haul realize we do better with real food and less "products." Having said that, sometimes conveniences are necessary in the real world.

I keep a few Quest Bars on hand for times when I've worked many days Ina row and I'm running low on real food to take to work. I also keep Quest Chips in the pantry since they are handy for road trip snacks.
