Food is symbolic of life. I’ve been a food writer in recent weeks with a story about Krispy Kreme and another about American beef . Seiyu, Wal-Mart’s Japan unit, is the first major Japanese retailer to start selling American beef after a three year hiatus caused by the mad cow scare. My premise is that chains selling fattening food like Krispy Kreme are gaining acceptance in Japan as the nation grows fatter and get used to greasy and rich food like chocolate, ice cream and doughnuts. What kind of a relationship is more like Krispy Kreme vs. whole wheat bread? What is a staple in life and what is just junk?
