Books promotes functional medicine, which means focus on causes not symptomes, treat (medically) each person as an individual, not as statistic Joe/Karen. One approach doesn't fit all. And yay for that! And then, wrapped in nice scientific wrap we get this: Mysterious illnes? It's probably an allergy or xyz poisoning. Detox and diet is the cure (common sense- there's an idea! Yes, I know, less and less people are familiar with the concept, so maybe it's good to be reminded of it sometimes) Lifestyle matters. Diet matters. Nutrition matters. Exercise matters. Enviroment matters. "Balance" approach of "not too much and not too little" is way to go (really?). All that can beat our faulty genes. And sprinkle on top with a little bit of mindfulness, meditation, and Chinese grandma's remedies. Oh, and Mediterranean diet with personalised supplements. I mean, you had to live under the rock for the past 10-15 years not know all that (or at least heard about it). It's on TV, radio, Karen's magazines, Joe's magazines, endless books for different type of readers.
The Disease Delusion basically is all about how the food and environment talking to/influencing your genes (and of course bit more), put together in one lengthy book, written in very aprochable smart and scientific language, with lots of gene and mitochondria talks. And for people searching mystery orgins of their weird disease- they might find some ideas toward the solution here (spoiler alert- it might be your diet or toxic paint, or even your perfume or dental filler- not being sarcastic, worth checking). I wish they would include low histamine tolerance problem- it's right up their alley, weird symptoms, lot of people are unaware of having it, food is the poison.
Since I've read similar books about nutrition and how food affect us, I didn't find anything here that I would think "Now that's a wow news!", nothing revolutionary. Half way through you kinda get the idea.
I didn't like "tests" in the book- they felt like reading a horoscope- everyone will find something there to say "YES! Thats me!"
This book is a good reminder though of all the things we should be doing and most of the time we dont.
