The Food Timeline

Marine phytoplankton could be added to that list: http://www.fastcoexist.com/1680062/plankton-the-most-sustain...

6000 years between unlevened and yeast bread seems along time. I would have expected naturally occurring yeast to have hastened this.

boy, the 19th and 20th century sure introduced a lot of crappy products thinly disguised as food.

Potentially a great resource.

So cool thanks!
