Book excerpt: Sam Kass, former chef to the Obamas and White House food policy advisor, makes it easier to do a little better for your diet--and the environment--every day, through smart ways to think about shopping, setting up your kitchen so the healthy stuff comes to hand most naturally, and through 90 delicious, simple recipes. JAMES BEARD AWARD WINNER • IACP AWARD FINALIST This book lays out Kass's plan to eat a little better. Knowing that sustainability and healthfulness come most, well, sustainably when new habits and choices seem appealing rather than drastic and punitive, Kass shares his philosophy and methods to help make it easy to choose, cook, and eat delicious foods without depriving yourself of agency or pleasure. He knows that going organic, local, and so forth all the time is just not realistic for most people, and that's ok--it's all about choosing and doing a little better, and how those choices add up to big change. It's the philosophy he helped the Obamas instill in their home, both in Chicago and that big white one in Washington.
