What if the food you eat could rewind your biological clock?

'Clear and compelling' Chris van Tulleken

'Really interesting and insightful' Joe Wicks

'Fascinating' Tim Spector

From the rising incidence of cancer in the under-50s to increased infertility rates, there are signs everywhere that growing numbers of us are ageing too quickly. Why? Many believe there’s one major our diet.

Ageing reflects a fragile balance in our cells between damage and repair. Sugar, excess calories and gut inflammation are all common sources of damage, but if we instead fuel our body with valuable micronutrients, we can lower our disease risk and age markedly slower. Until recently this process was impossible to measure, but with new breakthroughs we can even assess the age of individual organs, giving rise to a new science of food that might save us.

Join Dr David Cox as he meets the experts attempting to understand what’s accelerating our biological clocks and what we can do about it. Along the way you’ll learn everything from why we become more acidic as we age, to why omega-3s are one of the most powerful anti-ageing supplements, to the simple adjustments to your cooking that will help you age better.

The Age Code urgently pinpoints why our eating habits must change and what we can all do to live longer and healthier lives.

Review of advance copy received from Netgalley
February 4, 2026
The Age Code by David Cox certainly gave me a lot to think about. As I was reading, I found myself making notes; particularly around foods I should be including (and avoiding) in my diet.

The book explores why many people are ageing too quickly, how this shows up in our bodies, and what we can do to slow that process through diet. Cox looks at the effects of fast calories and overconsumption and the negative impact these have on our health, drawing a clear distinction between biological age and actual age. 

There’s a strong emphasis on low-AGE eating, reducing ultra-processed foods, and supporting the immune system.  There is a lot of science in this book! At times, I found this heavy going and had to read and reread in order to absorb and understand. The writing is well supported by research, projects, and case studies.

The book is clearly structured in two parts: part one focuses on ‘the problem’, while part two offers practical options for ‘healing’. It’s a very interesting and thought-provoking read, and I can see myself returning to it again. I’d definitely recommend it to others; especially anyone interested in ageing, health, and how everyday choices shape our long-term wellbeing.

I received a free advance review copy from NetGalley, and this is my honest review.
