4. They show off the color and texture of the food. This is just my opinion but I think its nicer to open a cabinet and see the food itself instead of all the packages. I like seeing the different colors and textures of the food - cacao nibs, oats, quiona, rice, chickpeas, dates, etc. When it looks nicer I feel like I'm more conscious of eating whole food in it's natural form. Let the food speak for itself - it doesn't need all the marketing on the packaging!
