Food nationalism or food racism?

A good post in a good blog

"I've been pondering the notion of food racism lately....

Given Brillat Savarin's quote "tell me what you eat and I will tell you who you are" it only bares to reason that food in many senses becomes symbolic of difference, similarities and cross cultural miscommunication

Michael Pollen wrote that colonisation of one country over another starts with diet.

I still think back to the stifled work lunches and dinners between foreigners and Cambodians, where foreigners would pick at the Khmer food on the plate in a way that was symptomatic of more than just a reluctance to "break bread" with their dining companions.

So I was thinking of all the racist slurs for the "other" based on food such as:

Kraut
Curry muncher
Dog eater
Limey
Twinkie
Bounty Bar
coconut
frog eater"
