Earlier this year, New York Times columnist Michael Pollan wrote an extensive article called Unhappy Meals. The bottom line was that we should "eat food." What prompted Pollan to take over 12 columns of newsprint to say this is that most of what passes off as food is not really food. Instead, what we find on our grocery store shelves are products of the food science industry, most of which have proven to be less beneficial–and sometimes even harmful–to health. Step away from the grocery store. Return to the garden.
