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!

What Your Doctor Isn’t Telling You About Food is an eye-opening and thought-provoking guide to understanding the connection between what we eat and how we feel. I really appreciated the way it explores modern diets and the many factors that can influence our health, while encouraging readers to think more carefully about their everyday food choices.

The book presents a lot of useful information in an accessible way, making complex ideas easier to understand without feeling overly technical. I especially enjoyed the focus on looking beyond popular diet trends and asking better questions about nutrition, ingredients, and long-term health.

It’s the kind of book that makes you pause and reconsider some of your usual eating habits. Whether you are interested in nutrition, healthy living, or simply want to become more informed about the food you put on your plate, there is plenty here to think about.

Informative, engaging, and genuinely thought-provoking, this is a worthwhile read for anyone who wants to understand food and health from a broader perspective. Five stars from me!

Very comprehensive informative book about the benefits of a plant based diet. As a vegan PB woman myself, I would not say I learnt a great deal more facts but it is always reassuring to read all the health benefits from this type of diet. What I liked was all the medical investigations mentioned in the book. Yet they were all explained in a very clear way. No need to be a scientist or a doctor to understand this book.

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.
