Yes, the sugar industry was not silenced by this book, so the fight continued. And I am sure you can come up with criticisms about any research publication. But the main point is undisputed: the "low-fat" science at that time was not purely science. It had been influenced - for years - by lobbyists and scientists with a personal agenda.

Then it becomes like so many topics these days: when people (I don't mean you anewvillager) throw enough counter arguments - true or not - distinguishing the truths becomes harder and harder, certainly for the population at large, not so well versed in the subject.

[BTW: I have no affiliations whatsoever with the author or the books, other than that I read it]
