Don't let the expiration date make you throw out food so fast. 

A new report from the Natural Resources Defense Council and Harvard Law School says Americans are throwing out food too soon because of confusion over what expiration dates really mean. Most people mistakenly believe expiration dates indicate how long the food is safe to consume - but it's really just an indicator of peak freshness. For example, eggs are generally safe to eat three to four weeks after they expire - so long as they've been in the fridge, that is. And frozen foods can last even longer. The authors of the report are calling for more consistency in use-by dates.
