The food industry and our very culture have also shaped our perceptions. In America we are taught that bigger is better, large portions indicate value, and excess is a right. On top of this, many advertisements promote the superiority of perfectly formed and colored fruits and vegetables. Moreover, supermarket packages carry a confusing combination of “sell by”, “use by”, or “best before” dates that have little to do with food safety but a lot to do with what gets purchased and discarded.
