This important open letter and report was released in New Zealand today. I'm happy to give it my full support. Physicians and Scientists for Global Responsibility has been around for 25 years, consistently raising the important issues. They've done a great job highlighting the problems in our health system and the growing understanding that diet and insulin resistance are the key drivers of our current health crisis. Yet we still have virtually no policy or meaningful action addressing this root cause. Please support this, share it widely, or advocate politically with your vote this year if you get the chance. Here is the link to the open letter and the full report (there's also a 3-page summary). psgrnz.substack.com/p/open-l… KEY POINTS: THE METABOLIC PATHWAY TO CHRONIC ILLNESS: 1. A single systemic metabolic & mental health crisis reframes many diseases as one metabolic failure. 2. Glycaemic and insulin stability underpin metabolic health & reflect core physiological regulation. 3. Insulin & inflammation as metabolic mediators. Displacing the single disease-specific approach. 4. Multimorbidity as signal, not just coincidence. Conditions share common upstream drivers. 5. Cumulative processed & refined carbohydrate exposure. Not just sugar, not just calories. 6. Nutrition & diet guidelines developed to avoid deficiency, not assure functional sufficiency. 7. Macronutrient hierarchy inverted. Carbohydrates structurally privileged over fat and protein groups. 8. Insulin as primary risk biomarker overturns cholesterol primacy.
