Summary

Written by a model from the transcript; not yet reviewed.

This episode explores how ultra-processed foods and modern diets impact human health, development, and chronic disease, featuring research from Dr. Michael Goran. The discussion examines how these foods affect the body far beyond simple weight gain, influencing early developmental processes, brain structure, and metabolic function from infancy onward. The conversation covers the specific mechanisms of alternative sweeteners, the hidden dangers in infant formulas, and the profound benefits of returning to real food and scratch cooking.

  • Cut back on ultra-processed foods by even 10% to meaningfully reduce type 2 diabetes risk. 9:13
  • Eliminate liquid sugar calories entirely, as they cause rapid glucose spikes and liver fat accumulation. 35:22
  • Choose lactose-based formulas over corn syrup solids for infants to support better blood sugar regulation. 51:01
  • Adopt simple kitchen processing steps, like buying plain yogurt and adding your own flavorings. 1:14:42

Highlights

  • 7:32

    Meta-Analysis Consistencydata

    Dozens of meta-analyses consistently show that ultra-processed foods affect almost every health outcome looked at, including obesity, diabetes, mortality, and brain health.

  • 20:20

    Sweeteners Trick the Bodyinsight

About this episode

Email Copy: The conversation about ultra-processed food needs to include more than what it does to our weight. We also need to talk about how it may affect our memory, our mood, and the way our children’s brains develop. Because the consequences of what we eat can reach far beyond what we see on the scale. Today on The Dr. Hyman Show, I’m talking with Michael Goran, PhD, a professor of pediatrics and researcher who has spent more than 35 years studying how food shapes our health. We explore what the science tells us and where to start making changes. We discuss: How ultra-processed foods may be affecting your mood and memory, beyond their impact on weight What a study of children’s brain development could mean for the foods we feed our families Why cutting back on sugary drinks is one of the first changes to consider What to know before choosing stevia, monk fruit, or other sweeteners as healthier alternatives Simple ways to eat fewer ultra-processed foods without spending hours in the kitchen I’ve seen how learning to prepare even one meal can change the way a family eats. Michael makes the point that you can start smaller still: Buy plain yogurt and add your own fruit. That counts. So does making your own salad dressing or learning to roast a pan of vegetables. These are skills you can use for the rest of your life, and every one gives you more control over how you feed yourself and the people you love.
