TED on Sunday: Mark Bittman on How We Eat

How and what we eat was back in the news this week, as First Lady Michelle Obama highlighted the importance of moving to a less processed, more nutritious and locally grown food supply by planting a vegetable garden on the White House lawn. In this talk from the 2007 EG (Entertainment Gathering) conference -- a TED offshoot launched in 2006 by TED founder Richard Saul Wurman -- New York Times food writer and cookbook author Mark Bittman traces the 20th-century transformation of food production from a healthy, largely local affair to an industrial-scale activity that is ruining our health and killing the planet. Your visits to the supermarket will never be the same. (Filmed: December 2007. Running time: 20:08.)
