Around the country today were thousands of events celebrating "Food Day" --- modeled after Earth Day. I spent part of my day at a Food Summit sponsored by Stanford University where I had the opportunity to share the work Kaiser Permanente has done to spread healthcare based farmers markets around the country and to help bring sustainably produced foods into a number of Bay Area hospital food systems.
Ultimately, every day could be food day. The best thing for everyone's health is to prepare meals from actual recognizable food. Shop the perimeter of the grocery store or at your local farmers market, sharpen your chef's knife, mince, chop, slice, dice, julienne, and macerate on your two cutting boards then marvel at the tasty food you created for friends and family while helping out your budget.
The sharp knife and some basic kitchen skills make the right thing easy to do.
