We engineered foods that make us want more. Now we've engineered drugs that help us want less. What does that say about the world we've built? New article ↓ sub.gutbites.org/p/have-we-en... #GLP1 #UltraProcessedFoods #NutritionScience

GLP-1 feels like a miracle. That may say as much about our environment as the drug itself. When appetite, satiety, and metabolism become disconnected, restoring one signal can feel transformative. But why did the system need rescuing in the first place? sub.gutbites.org/p/glp-1-feel...

Whole foods can “hide” calories inside intact plant structures. Processing breaks these barriers, making energy easier to absorb. Why food structure matters: sub.gutbites.org/p/why-whole-... #GutHealth #NutritionScience #FoodScience

We didn’t miss the microbiome because it was small. We missed it because it was resilient. Now that resilience is fading, we’re seeing what it did all along. It’s not one nutrient or one fix. It’s the system. sub.gutbites.org/p/how-did-we... #Microbiome #GutHealth #Nutrition #MetabolicHealth

What you eat matters, but what you eat together may matter more. Meals, not foods, drive biology. sub.gutbites.org/p/the-biolog...

Moving beyond diet camps: a microbiome-centered view of nutrition. Food quality shapes metabolism, appetite, and long-term health more than labels like low-carb or plant-based. sub.gutbites.org/p/why-diet-w...

www.news-medical.net/news/2026012... Gut microbes shape cancer outcomes by regulating dietary asparagine. Bacteria that degrade this amino acid may limit immune cell function and weaken anti-tumor responses, while greater asparagine availability appears to support stronger cancer-fighting immunity.

A new study shows that binge drinking can damage the gut barrier, allowing bacteria and toxins to enter the bloodstream and trigger inflammation. The injury is driven by neutrophil extracellular traps (NETs) in the small intestine, and blocking NETs reduced damage. news.harvard.edu/gazette/stor...

Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other. Shared by @gizmodo.com: buff.ly/yAAHtHq

Great article! And not all processed foods are equal—what’s missing (fiber, polyphenols, healthy fats, micronutrients) is as important as what’s concentrated (sugar, additives, saturated fat, sodium). Food quality can be captured by ratio balances (e.g. carb-to-fiber). gutbites.org/2025/11/12/u...
