Processed Foods Forever
The world of processed foods became popular with Boomers. If it can come in a can, a Boomer will eat it. While Boomers were growing up, supermarkets and food companies were still learning and releasing new ways to keep food fresh for longer.
This type of behavior comes with the territory of how you were raised, honestly. Old habits die hard, and Boomers will never give up their can of Spam.
