Ultra-Processed Foods, Sugar & What the Evidence Shows | Michael Goran, PhD

In this episode, Dr. Michael Goran—one of the leading scientists behind the 2025 Dietary Guidelines for Americans—joins the show to reveal what the evidence says about highly processed foods, refined grains, and added sugars. As the researcher who led three critical umbrella reviews that shaped these landmark guidelines, Dr. Goran walks us through the methodology behind the recommendations and shares findings that may surprise you: a 10% reduction in highly processed food intake can lower diabetes risk by 14%, replacing just one serving of refined grains with whole grains reduces mortality risk by 13%, and cutting one sugary beverage per day can slash diabetes risk by 26%. We also explore a paradigm shift in nutrition science—the idea that the burden of proof should now fall on highly processed foods to demonstrate safety, rather than requiring whole foods to prove their benefit.

The conversation gets practical when we dig into what these findings mean for families. Dr. Goran challenges some of the guidelines' recommendations (like avoiding all added sugars until age 10) while strongly endorsing others—particularly the emphasis on eliminating liquid sweetness from children's diets, including fruit juices, sports drinks, and even diet sodas, which show concerning links to all-cause mortality. We discuss "kitchen processing" as an alternative to factory-processed foods, the importance of developing basic cooking skills, and why the first few days of dietary change are the hardest but also the most rewarding. If you want to understand what the new dietary guidelines mean for your health and your family, this conversation offers both the science and the practical wisdom to make meaningful changes.
