The woman, whose name is Beautiful Existence, says her food challenge grew out of a passion for knowing more about the culture of companies and her background in marketing. She says it wasn't as difficult as you might expect.
"I actually had quite a few things that changed during this last year that offered me a really great variety, just besides that they had the different brands. They actually kept changing the food items as well, so it was actually really easy for the entire year," said Existence.
Existence is no stranger to these types of challenges. In a previous year, she did all her shopping at Goodwill stores.
