Slow food is a concept that starts to get popular in the late 1980s. It is not to combat fast food, but rather to appreciate food. Well the French may be the best example where lunch or dinner can easily take 3 to 4 hours.
I guess it’s really like mindful eating. Recently I also come across the term fooding, which means food with feeling.
This evening I had slow food at Adagio, a bed & breakfast one hour outside Taipei. The whole meal had 8 Taiwanese courses over 2 hours.
To me slow food is not about how much money you spend on food, but rather how much time you spend on food.
