Still sharp. Still strong. Still you - at 50, 60 and beyond.
Science-grounded longevity isn't restriction. It's learning to read the signals your body has always been sending - through your genes, your gut, your hormones, and your cellular energy system.
The Ascension Diet:
Already Whole
The New Science of Cellular Health Through Food, Breath, and Inner Awareness.
A four-part journey - from why conventional nutrition falls short, through the ten foundations of nutritional architecture, into the deeper biological intelligence running inside every cell, and toward the signal beneath the signal your body has been sending all along.
Not a set of rules to follow, but a way of learning the language your cells have always spoken. Written for the intelligent general reader - plain language, without simplification.

Food as a conversation with your biology.
The traditional ways of eating that quietly produce long, healthy lives - around the Mediterranean, across Okinawa, through the Andes and beyond - all answer, in their own idiom, to the same ten biological foundations. This book is not a prescription for any one of them. It is a framework for the why beneath them, so you can recognise what your body has been asking for in the foods already around you.
"What is preventing this person from experiencing health? That question points toward the present and toward function - and generates a framework."
Ten biological foundations.
Each foundation is a doorway into how food communicates with your body. Read together, they form a framework for the why behind healthy longevity - not a set of rules to follow.

Welcome
This channel is an opportunity to pay it forward, and offer what I was looking for for such a long time, in terms of real nutrition and health information, grounded in science, and at the same time holistic and with a bigger understanding of the nature of our human-being-ness. Not science twisted or cherry picked to sell a supplement or 'health product', not another fad diet. Just real and relevant nutrition information to support healthy longevity.

They Rewrote Australia's Food Rules — Protein is Protein… Right?
On 2 September 2025 the legal definition of genetically modified food was narrowed. Proteins grown in bioreactors now fall outside it, which means no pre-market safety assessment and no label telling you how they were made. A year earlier I wrote to the regulator's board asking them to slow down. Part one is what changed, what the evidence says, and what I think it means for the way you shop and eat. Part two is how the decision happened, and what I think we should be asking for.
