Bestselling authors Mark Bittman and Dr David Katz cut through all the noise on food, health, and diet to give you the real answers you need.

What is the ‘best’ diet? Do calories matter? And when it comes to protein, fat, and carbs, which ones are good and which are bad? Mark Bittman and Dr David Katz answer all these questions and more in a lively and easy-to-read Q&A format. Inspired by their viral hit article on Grub Street for New York magazine, Bittman and Katz share their clear, no-nonsense perspective on food and diet, answering questions on everything from superfoods and basic nutrients to fad diets.

Topics include dietary patterns (Just what should humans eat?); grains (Aren’t these just ‘carbs’? Do I need to avoid gluten?); meat and dairy (Does grass-fed matter?); alcohol (Is drinking wine actually good for me?); and more. Throughout, Bittman and Katz filter the science of diet and nutrition through a lens of common sense, delivering straightforward advice with a healthy dose of wit.
