Some of this book seems like good advice e.g. eliminating simple carbs & processed/packaged foods, and switching to high-quality (probably organic) vegetables and high-quality meat & eggs (e.g. genuine PASTURE-raised flesh and PASTURE-raised eggs, not the meaningless "free range chicken" nonsense one sees in stores & on restaurant menus).
Some of this book seems like a big stretch, e.g. the assumptions & proclamations about what our ancestors used to eat (i.e. almost all fatty animal products, very few fruits/vegetables). I consider those statements about the nutritional makeup of our ancestors to be a series of presumptuous, unsupportable statements that should be taken with several grains of salt.
As intellectual & informational balance to Perlmutter, I recommend that all thinking people also read at minimum "The Omnivore's Dilemma" by Michael Pollan and "Reversing Diabetes [sic]" by Dr. Neal Barnard.
Not disputing Perlmutter's recommendations, because as I said above, some of his advice IMO has merit, but in a one-year trial I myself have lost most of my visible body fat and achieved blood-chemistry and BMI results as good or better than Perlmutter's ideal goals, by adhering to the strictly whole, plant-based foods, low-fat, low-glycemic-index dietary recommendations proposed by Neal Barnard ("Reversing Diabetes"),T. Colin Campbell ("The China Study") & Caldwell Esselstyn ("Prevent & Reverse Heart Disease"). The only supplements I take are vitamins B12 and D3.
IMO, in "Grain Brain" Perlmutter makes some good points that seem to have merit, but also makes some seemingly unsupportable statements/proclamations that make me raise an eyebrow about following his recommendations unquestioningly. Before going whole-hog for any of these nutrition-for-life books, I highly recommend reading a balance of viewpoints.
