Ultra-Processed Foods and Your Health: Why "Healthy" Packaged Foods Are Making You Sick
Episode Summary
Colin Renaud (DC, PA-C) and Dr. Sasha Rose co-host this nutrition-focused episode in the absence of Cole Siefer. They break down what ultra-processed foods are, why they are designed to be addictive, and how they drive metabolic disease, gut dysfunction, and emotional eating patterns. Both providers share clinical case studies showing how dietary change alone produced dramatic improvements in pain, weight, and energy. The episode closes with practical, non-perfectionist strategies for patients who want to start eating better without overhauling their lives overnight.

Quotable Moments
“Food is supposed to rot, right? It's an organic matter. It's supposed to go bad. You buy a bag of cookies or chips and you could have that for years and open it and it's like, 'Oh, this looks just like it looked on the first day I bought it.'”
“These ultra-processed foods are designed to give you that feeling. And if you do it enough, it's addicting. The feeling is addicting. The substance is addicting.”
“I always try to tell people that no one is asking you to be perfect. And I think that's what they think they need to do, but it's far from it.”
“It was removal of gluten and she was like running marathons. And when the pain went away, it was not only knee pain, it was hip pain, it was arthritic hand pain. It was insane.”
“When you're trying to get a patient to change, if we can provide the time and the space and the resource to educate patients so they can learn this stuff on their own and then they own it for themselves, that's really where the benefit comes from.”

FAQ
Nutrition FAQ
Ultra-processed foods are industrial products containing emulsifiers, artificial flavors, preservatives, and modified starches not found in home cooking. They disrupt the gut lining, alter satiety signaling, and trigger dopamine-driven addiction cycles. They are designed to be hyper-palatable and shelf-stable for years.
Emulsifiers like polysorbate 80 disrupt the protective mucous layer of the small intestine, increasing intestinal permeability (leaky gut) and promoting pro-inflammatory bacteria. This leads to systemic inflammation that manifests as digestive symptoms, joint pain, skin issues, and metabolic dysfunction.
Yes. High sugar, added fats, and flavor enhancers trigger dopamine release creating a biochemical addiction loop comparable to alcohol or opioids. Research suggests it takes 21 to 28 days off a specific food to begin breaking the addiction cycle, and withdrawal symptoms are expected.
Yes. In one case, a woman in her early 60s recommended for knee replacement had all joint pain (knees, hips, hands) resolve completely after removing gluten. The inflammation driving her pain was dietary in origin, something no specialist had investigated.
Research estimates that approximately 85% of human disease is driven by poor diet. This includes insulin resistance, weight gain, non-alcoholic fatty liver disease, cardiovascular disease, and chronic inflammation.
Stay on the perimeter of the grocery store where fresh ingredients are (produce, meat, dairy). Any product with more than six ingredients or ingredients you cannot recognize is likely ultra-processed. Start with one small change rather than overhauling everything. Baby steps sustained over months produce dramatic results.
