These days it feels like there have never been more wrong ways to eat right. Everywhere you turn there's a new rule, a new label, or some flashy food trend trying to get your attention and your money. Dr. Marion Nestle is the OG of cutting through the trends, calling out an industry that's built to boost profits, not necessarily our health. Twenty years after she wrote the original guide to surviving the supermarket, she's back. And at 89, she's taking on everything from ultra-processed foods to grocery delivery apps in an updated edition of her classic: What to Eat Now: The Indispensable Guide to Good Food, How to Find It, and Why It Matters.
