On my way home today, I came across this radio interview with a guy who decided to try out the cuisine from a different country everyday!
Check out Noah Galuten’s Personal Food Project and his writing about his food and cultural experiences: http://manbitesworld.com/
Besides the color, smell, taste. funny stories, and surprising encounters, I wonder if he could address the health philosophies from different cultures and how they are embedded in the preparation, cooking, and presentation of the authentic dishes.
BTW, this site could also be a nice source to find good ethnic restaurants, especially in Los Angeles! But vegetarians and vegans would have to be careful when it comes to your pick
