What to Eat Now: Dr. Marion Nestle on Modern Food Confusion, Diet Fads, and America’s New Guidelines

Bill Bernardoni opens today’s episode with Dr. Marion Nestle — one of the most trusted experts in American nutrition and author of the new book What to Eat Now. Dr. Nestle explains why she rewrote her classic guide from the ground up, how the food landscape has radically changed in the past 20 years, and why supermarkets, product lines, diet culture, and plant-based trends all look entirely different today. She also breaks down the explosion of bottled waters, cannabis edibles, online grocery shopping, and the rise of the “all meat” diet, offering clear science-backed insight ahead of the upcoming U.S. Dietary Guidelines. A sharp, thoughtful conversation that cuts through the confusion surrounding food, fads, and what healthy eating actually looks like in 2025.Do you trust modern food advice — or has the explosion of diets, trends, and conflicting guidance made eating healthy harder than ever? Let us know your thoughts in the comments.Follow Bill on X at @BillBernardoni, explore his work at Bernardoni.media, and read his latest writings at Bernardoni.blog.
