Thanks for being so sweet about this. You are a lovely, kind, considerate person - that shines through your posts - and I would hate to offend you.
There are two main groups of people trying to make a profit from rosacea: those pushing product, whether its something they made or something they're being paid to promote, and those pushing ideas and charging for them.
Like most rosaceans, I find the latter tacky and exploitative, but don't object to any of them per se, as long as it's kept honest. Hence our rules that anyone posting about something in which they have a financial interest must prominently declare that interest, and that they should respect the fact that the boards are meant for the free exchange of helpful information.
Since this author has taken the time and trouble to include a lot of reasonable background information and isn't just trying to sell a few words of info, then I have no objection. After all, you bought the book and felt you weren't being ripped off, and that's the test, isn't it?
Thanks for listing the treatments being promoted. Quite a few members have tried various combinations like that over the years and seen modest improvements, so it will almost certainly fail to live up to his claims of banishing rosacea "permanently", putting people into "complete remission", and making it "almost impossible to get rosacea again", but we shall see.
As for the dietary suggestions, they mostly sound very sensible. Boosting Omega-3 and cutting back on Omega-6 is now so widely recognised, few regard it as anything other than mainstream nutritional advice, ditto not drinking soda.
Avoiding dairy products and red meat is more controversial, but I'm currently reading "The China Study" by T. Colin Campbell, PhD (an Emeritus Professor of Nutritional Biochemistry at Cornell University who has written more than 300 research papers) with his son Thomas M. Campbell II (BenBella Books, 2004). This really should be read by everyone following a high protein diet, especially if they're feeding that same diet to other members of their families. The Campbells don't actually use the phrase "dicing with death", but it certainly makes for scary reading. (Perhaps I should start a new thread on that in the diet section.)
