In a couple of years, maybe, folks will greet each other on Oct. 24 with cries of “Happy Food Day!” The event, created by the Center for Science in the Public Interest, hasn’t yet achieved the high profile of, say, Earth Day, but it’s well on its way, with talks, dinners, demos, and more in Massachusetts and the nation.

Now in its second year, Food Day — a “movement for healthy, affordable, and sustainable food,” according to the event website — takes a big-tent approach. All kinds of organizations are getting into the act with many free and inexpensive events throughout the week. You might join a community center potluck or take advantage of “workout Wednesdays” at Shaw’s supermarkets.
