Content was redundant and did not feel like it added much to the conversation, but I do enjoy the conversation and was a strong reminder for eating plant based or at least incorporating more plant based meals in a diet.

Didn’t tell me much I didn’t already know, but sometimes you need to be reminded of what proper eating should look like!

[Tim Webley · Rating 5 out of 5]

Found the book very easy to read and understand. Gave us evidence of what a healthy diet consists of. Very informative.

Got this book from Waterstones slightly before the publication date it seems, lucky me.
Dr Desmond goes into a lot of detail about nutrition and what the research says about food and what to eat to maximise your health span.
