I'm referring to the study the book focused on? The study and the book are 2 different things.
And ya, if you use a dismissive facepalm emoji you're going to get a petty lame macho insult lol
As far as I know, the China Study does represent a good argument for decreased meat consumption. One advantage that would be very difficult to replicate in the west is that the period under study was mostly before the current economic boom, and thus before the current onset of wheat and sugar. Since the period looked at in the China study, processed carbohydrate consumption has exploded in China, and disease rates have gone up and a lot. It would be difficult to replicate that study today, as there would now be additional variables confounding the data.
Within the western countries, meat consumption is typically coupled with processed carbohydrates. For example, a hamburger is paired with a white bread bun, French fries, Coca Cola, and ketchup. That makes it very difficult to assess if the hamburger itself is bad for you, as the person eating a vegan burger would be doing just as badly. The China study in contrast probably didn't have that coupling, since sugar had not yet taken off there.
As Dr. Jason Fung has noted, the Chinese had low rates of type-II diabetes on their historic diet of white (not brown) rice. It went up once white sugar was imported from the west.

What is a confounding however, is that Asians are adapted to better digest soy. East Asians are more likely to have the gut bacteria to convert the soy isoflavone daidzein into s-equol.
S-equol has many wonderful effects on the body. It binds to and thus neutralizes dihydrotestosterone, which can reduce hair loss, reduce benign prostatic hyperplasia, slow down prostate cancer. In fact, the drugs for those conditions often use the same mechanism. S-equol also binds to the estrogen-beta receptor, which gives it other benefits such as relieving hot flashes.
It's a regional dietary adaptation, not unlike the eskimos and animal protein, white people and lactose, etc. To go into greater detail, the eskimos are much more efficient at converting animal protein into glucose, and white people are more likely to have the lactase enzyme.
If you're an equal producer, you should probably eat soy on a regular basis.
Maybe we can talk about what a bunch of BS the keto diet is lol
The keto diet has helped a lot of people.
