For 40 years, every time nutrition has found a new villain, the food industry has handed us a new label to go with it: non-fat, no GMOs, gluten-free, no seed oils, and now, non-ultra-processed. We have more experts, more studies, and more food rules than ever before, so why does standing in the grocery aisle still feel like such a guessing game?

Join Holly and Jim as they sit down with Tamar Haspel, the James Beard Award-winning Washington Post columnist behind Unearthed and author of To Boldly Grow, to pull apart the ultra-processed food debate and ask whether today's labels are actually helping us eat better or just making us easier to market to. Tamar doesn't just write about food from behind a desk: she gardens, fishes, raises chickens, and runs an oyster farm on Cape Cod, and she brings three decades of reporting, real skepticism, and zero patience for diet cranks to the conversation.

You'll hear why the food world keeps repeating the same mistake, what a cage full of B.F. Skinner's pigeons can teach us about our relationship with food, and what's really driving overeating once you strip away the marketing.

Discussed on the episode:

The decades-old pattern that explains why every new food "villain" feels eerily familiar
The bizarre pigeon experiment that reveals why we're so convinced certain foods are "good" or "bad" for us
Why a bowl of crushed cereal proved more about overeating than years of processed-food headlines
The blunt case for why "everything in moderation" might be the most useless diet advice out there
The one-sentence grocery store rule that could replace almost every food label you've ever side-eyed
How GLP-1 medications could end up reshaping the entire food industry, not just individual waistlines
The "healthy" nutrient claim, Tamar says, is wildly overrated and the snack everyone blames for something it's not even guilty of
