Redesigning the Natural History of Disease: How Human-Made Environments Shape Health — and How We Can Shape Them Back | ChatGPT5 & NotebookLM

Chronic non-communicable diseases (NCDs) such as cardiovascular disease, diabetes, cancer, dementia, and depression now account for nearly three-quarters of global deaths. Traditionally, these diseases have been framed as the inevitable outcomes of biological aging, genetics, and individual “lifestyle choices.” This white paper challenges that paradigm, demonstrating that the so-called “natural history” of these diseases is, in fact, largely anthropogenic — shaped by human-designed systems, policies, and environments.

Upstream determinants — including food systems, housing quality, advertising landscapes, workplace structures, and environmental exposures — create exposure fields that drive disruptions in a small set of shared biological pathways: metaflammation, insulin resistance, endothelial injury, circadian misalignment, and microbiome disruption. These pathways explain why single exposures influence multiple diseases simultaneously, and why population health cannot be restored by downstream treatments alone.

Recognizing the designable nature of disease trajectories reframes prevention, accountability, and equity. Human-made causes imply human-reversible solutions: redesigning upstream determinants through policy, regulation, and systemic advocacy can bend population risk curves earlier, faster, and more equitably than reactive healthcare ever could.

This reframing calls for a paradigm shift in medicine, public health, and governance. Clinicians must integrate determinant histories and dual-lever treatment plans. Policymakers must deploy high-leverage interventions such as regulating harmful advertising, incentivizing nutrient-rich food systems, and redesigning urban spaces. Communities must be empowered to co-create healthier defaults. Together, these strategies represent a collective opportunity to reimagine health as a design challenge — one where prevention by design becomes the foundation for population flourishing.

Is pathogenic human interference the cause of our social and planetary woes?

“Life creates conditions conducive to life.” – Janine Benyus

As many of you who follow my blog articles may have realised, I have become captivated by Professor John McMurtry’s life work. His book, The Cancer Stage of Capitalism: From Crisis to Cure, has provided a unifying framework of meaning and understanding of all of the degenerative trends of our time. What you may not know, is that for over a year, I have been trying desperately to translate the medical concepts from my training from the level of the individual life host up to the social and planetary levels of life organisation. And by trying to do so, it was hoped that we would be better able to understand the pathogenesis of these degenerate trends, and be able to convince our policy and decision makers on what steps need to be taken at the local, regional and international levels so as to prevent and rehabilitate the social and planetary pathologies in our midst.

What I have just come to realise is that the difficulties I was having in accomplishing this goal had to do with a preconceived assumption that was a major mental block in going forward. That concept has to do with what we in the profession call, the natural history of disease. Read More
