Michael Greger: How Ultra-Processed Foods Could Cause Disease: Changes in Structure
Peer-Reviewed Research
Key Takeaways
- Choose whole intact plant foods over ultra-processed versions, even if they have the same fiber content (e.g., apples > applesauce > fiber-enriched juice).
- Opt for steel-cut oats or whole oat groats instead of instant oatmeal to reduce glycemic response and overeating.
- Avoid extruded/processed cereals (even zero-sugar options like Shredded Wheat) due to their high glycemic impact compared to whole grains.
- Prioritize fiber from whole foods (not supplements) for disease prevention and gut microbiome benefits.
Notable Quotes
“You can’t just take your magic bullet of Metamucil with your Wonder Bread. That’s not how fiber works.”
Bottom Line
Eat minimally processed, structurally intact plant foods (like whole grains, fruits, and vegetables) to optimize satiety, blood sugar control, and long-term health—don’t rely on fiber supplements or processed “whole grain” products.
