3) Claims that sound too good to be true.
Does fixing your digestion by eating a healthy diet sound too good to be true to you? Does a healthy digestive system having effects on the body as a whole sound fanciful?
Curing it all by avoiding gluten is too good to be true.
4) Simplistic conclusions drawn from a complex study. His conclusions and recommendations are anything but simplistic. Of course you would have to read more than the dust jacket to know this.
This he has done in all his conclusions. He simplifies studies down to mean what he wants it to mean.
5) Recommendations based on a single study. Read the bibliography.
Lots of citations but lots of claims. A single study per claim is not very much
6) Dramatic statements that are refuted by reputable scientific organizations. Perhaps, as you pointed out, not yet *endorsed* by "the authorities" but I don't see any refutation either.
So by saying that they’re not endorsed yet but will be then he’s not making refuted statements? You’re quite an optimist.
7) Lists of "good" and "bad" foods. Let's see.... Processed foods high in sugar and fake ingredients are bad for you and while fresh produce and protein are good. Is that really so unreasonable?
As was said in the review I posted he exaggerates negative effects of things. To be healthy no type of food needs to be demonized but it’s what sells.
"Spinning" information from another product to match the producer’s claims. What products?
Like I said, not all apply to him but with his constant releases of books & his work on the Dr. Oz show I’m sure he doesn’t need that money.
8 ) Stating that research is “currently underway,” indicating that there is no current research. Being honest about the current state of the scientific inquiry is a problem? I admire that Dr. Perlmutter always states the exact level of the source he is quoting, e.g. is this a study of rodents or people and what is the N=#. He is a doctor and a scientist, not “just some blogger”.
Actually, attacking the state of scientific inquiry is how he manages to sell things with very such weak “proof”.
9) Non-science based testimonials supporting the product, often from celebrities or highly satisfied customers. Dr. Perlmutter does have testimonials from people who have tried his approach successfully. This may not be "scientific" but that doesn't make it not real. It is clearly labeled as "testimonials" with all the YMMV caveats attached. I don't see anything wrong with this additional information in the same way that I don't see anything wrong with someone here on CWE telling their personal experiences with a particular medication. Doesn't mean that generalizes to everyone but it is interesting information nonetheless.
There are good reasons that science rejects anecdotal medicine. Having anecdotes doesn’t make research false but the fact that he would even include them in his book shows that he is more concerned with selling the product than properly proving it.
