Start with the title: "Everything we love to eat is a scam". I can provide lots of counter examples to that statement.
Other statements with my comments
"After reading it you’ll want to be fed intravenously for the rest of your life." - Look up total intraparenteral nutrition and see if you would prefer that to eating.
"Escolar is so toxic that it’s been banned in Japan for 40 years, but not in the US, where the profit motive dominates public safety. In fact, escolar is secretly one of the top-selling fish in America.". - By toxic the author means causes diarrhea due to unabsorbed oils/waxes. Also when we you hear that a lot of people are eating a lot of very toxic food, the food either is not very toxic or else not widely consumed.
"These fake foods produce shallow, flat, one-dimensional tastes, while the real things are akin to discovering other galaxies, other universes — taste levels most of us have never experienced." - I can imagine Galileo realizing that discovering the moons of Jupiter pailed in comparison to eating real Parmigiano cheese.
"Imagine if half the time you pulled into a gas station, you were filling your tank with dirty water instead of gasoline,” Olmsted writes. “That’s the story with seafood.”" - Zero calorie seafood, I never knew?
"Perhaps most surprising of all: discount big-box stores such as Costco, Trader Joe’s, BJ’s Wholesale Club and Walmart are as stringent with their standards as Whole Foods." - In my opinion, the more "hipster" a food establishment is, the less likely that they are really taking care of the food basics. When was the last time you heard of a large-scale McDonalds food poisoning incident? How about Chipotle?
This is one of those genres where books try to convince people that the sky is falling. In reality, we have never had such abundant, safe food in the history of humanity. Other than the people who truly have food allergies, the vast majority of people are really unaffected by any of these "revelations". In addition, especially for seafood, the substitutions are probably more ecologically sustainable.
