Episode notes
Modern Diet Versus Ancestral Biology
- Modern chronic diseases stem from the modern food system and lifestyle mismatches with ancestral biology.
- Brendan Ruh argues combining ancestral practices with modern science can prevent many common illnesses.
Disease‑Care Over Preventive Care
- The medical system is disease‑care focused and resists preventive testing like GI map unless patients are clearly sick.
- Insurance and practice constraints delay early detection of treatable conditions like H. pylori.
Cut Out Artificial Food Dyes
- Avoid artificial food dyes when simple natural color alternatives exist in foods.
- Brendan Ruh recommends cutting them out because they add no nutritional value and may carry risks.
