Food for Life is a thought provoking book on all aspects of our eating lives from nutrition to environmental consequences of our choices. Backed by research into the gut micro-biome and personalised nutrition studies Spector does a deep dive into what we should eat and why and, for the most part, it is a very interesting and educational read. Generally the advice is 1) eat minimally processed foods; 2) eat a wide variety of those foods; and 3) as rule Western people eat way more meat than they need so cutting down on that is good for you and the planet.
There are specific chapters on each food group you can dip into and out of as you need to without having to read the book from cover to cover.
Occasionally there will be mentions of his ZOE PREDICT study (which after reading the book I am still not entirely clear on the premise of the study or what "ideal" results might look like) and how his own results have influenced his personal food choices, which is great for him but I am not clear on how those same foods would or should influence my own choices as my body might react differently (I am a woman in my 40's not, like him, a man in my 60's: we have vastly different nutritional needs).
He constantly mentions many people get different results and will occasionally give averaged results as well as his own. But the issue I have is some people might treat this as gospel (its in a book and if it works for him it must work for me!). Most people reading this book would not be able to access this kind of personalised data and some of these results suggest certain foods (whole, unprocessed, fresh- like certain fruits or vegetables) should be avoided or at least reduced to occasional treats. I just cannot get enthusiastic about that. If you love bananas, eat the damn banana! It is a better choice than many you could be making like donuts, chips or chocolate. Likewise his attitude toward the use of pesticides in farming. Ok, I agree pesticides are not ideal however "Organic" does not equal no pesticides - it just means certain pesticides are not used. And again, eating non-organic fresh veg that you can afford is better than stressing yourself trying to afford smaller amounts of organic veg and filling up with processed foods. If you can afford it, great! Go for your life, but there is already so much stress and guilt around food (especially for women) why add more?
Overall this is an interesting read and his food specific chapters will make think about not just what your food choices do for you but what they do for the planet too. However the advice can be conflicting: In the chapter for Fish for example, Spector says that farmed fish is an environmental and animal well-being catastrophe, but in next paragraph states that if we continue to demand so much wild-caught fish we will cause total collapse of fish stocks - so which fish can I eat? What ethical dilemma should I have for dinner?
I will take this information on board but I will not be treating it like the final word. Yes, we need to make choices for our health and the environmental impacts do play into that, but ultimately I want to enjoy the food I eat.
