I was trying to catch up on what Peter Reinhart has been doing since he published his book on whole-grain breads. The whole grain breads in that book I found to be quite good, but the 80-page introduction to the technique was more than a bit overproofed, if you know what I mean.
I get the feeling like Peter Reinhart has accidental scorn for people outside of his baking community of bread-class demonstrations and industry events, and maybe isn't as plugged into smaller and online communities as much. You could pose a lot of the assertions and open-ended ideas into a Reddit thread and probably quickly get a lot of well-researched explanations and personal testimonials from people who have already "gone there" on any idea in this book, but Reinhart has a tendency to make it seem like he's Captain Kirk boldly going where no baker has gone before. It's not so.
The topic of this book is sprouted-grain breads. Those have existed for a long, long time. What seems to be new is the emerging supply of what amounts to diastatic malt powder, but made with wheat instead of barley, making that ingredient more available to more people.
I don't think I'd go so far as to call that a revolution on its own.
What Reinhart means by the revolution, I think, is that turn toward sprouted-grain breads could retrieve bread from the slander it's facing at the hands of gluten-free evangelists and keto dieters (known colloquially as 'dingbats.')
But the part of the book that justifies this point of view is woefully underbaked. I think it would behoove anyone who purports to write a book about bread and health to come up with an informed point of view through which to run the fantastic claims that those trying to sell a product can dream up. For example, a product called ProBioteen, which is basically spent brewery-grain flour, is said to be rich in prebiotics because it has been "fermented." But making the beer wort is a pre-fermentation step, unless you're considering the malting process as fermentation. And if you are, then ProBioteen has no more of a claim to "fermented" status than does a non-ProBioteen loaf which is fermented with normal baker's yeast or sourdough.
Gluten-free is apparently a market force, as painful as that is for me to admit, but I can't excuse a bunch of ad hoc theorizing over why separating bran from a 2nd run through the mill to make it finer before recombining it with the rest of the flour somehow produces a nutritionally-inferior whole wheat flour than does "whole-milling," and somehow explains why some "gluten-sensitive" people claim to experience no or fewer symptoms from "whole-milled" bread. Even if I grant that "gluten sensitivity" is a problem outside of celiac disease, I think I'm still on safe ground when I posit that a lot of people with "gluten sensitivities" do not actually have biological troubles eating gluten, and that perhaps a touchy digestion or an active imagination has caused them to associate any troubles with gluten in a bias-reinforcing way.
To the extent that gluten actually is a problem, then the real revolution would presumably be not to sprout the bread, which does nothing to the protein content, but to return to breads with lower protein levels. The high protein contents of modern-day flours are a relatively recent event due to excessive fertilizing and advanced plant breeding knowledge. In the past a 10% wheat flour would have been considered sufficient for bread-making, but modern flours claim 14% protein. That protein is mostly gluten, presumably.
Nevertheless, I personally am interested in sprouted-wheat bread, being recently convinced of the idea that humans evolved eating ripe plant seeds and tender plant matter. But since I already have a Reinhart book on bread-making and the main difference in this one is simply that the recipes use the new sprouted wheat flours or sprouted wheat pulp, I don't think I need to own this one in addition to the other one.
