How fresh is your snack?

Lay's Classic potato chips

Highly perishable foods such as dairy and meat have had manufacturing and/or best by dates on the packaging for years. In what seems to be an effort to get consumers to think of their snack foods and more "healthy" firms such as Lay's are now including a manufacturing and best by date on the packaging.

While fresh is certainly preferable, I don't know if this will convince anyone that a potato chip is a healthy snack. Tasty yes, but healthy perhaps not.
