Food on TED.com
Just a few presentations I've come across at TED.com. For those of you who don't know TED (Technology, Entertainment, Design) is an organization that promotes the talks and presentations of many different individuals in many different fields, "Ideas worth spreading" is their tag line. I found these talks and a number of others by searching "food" within the site.
I must say I don't always agree with what is being said but it certainly is interesting to hear another's perspective on food.
Some ideas for your consideration...
