The Age Code: The New Science of Food and How It Can Save Us

Rate this book
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.

This is yet another book about the 'biohacking' trend that seems to be massive right now.
I have read a few books on this topic as it is something that really intrigues me - however, I found this book to be much of the same but with more medical jargon.
I struggled with the amount of medical terminology and felt that because of this, a lot went over my head.
This book is OK - but there are more accessible and easier to read books on the topic than this one.

I couldn’t wait to start this book as it’s a subject I’m really interested in especially as I have grown older.

There was plenty of interesting information and it definitely made me rethink my lifestyle and diet.

The book was laid out well and the tables were great to refer back to.

A great insightful book which I would definitely recommend.

Thanks to NetGalley, David Cox and the publisher for an advance copy in exchange for an honest and unbiased review.
