Renowned neurologist David Perlmutter, MD, blows the lid off a topic that's been buried in medical literature for far too long: carbs are destroying your brain. And not just unhealthy carbs, but even healthy ones like

I received this book as an advanced copy from Good Reads. In this book Dr. Pearlmutter makes the case that many healthy problems currently endemic in our society are directly related to our over consumption of carbohydrates, particularly those from grain. He lays out the claim for how such a diet is counter to our evolutionary needs and then proceeds to make links between gluten insensitivity, neurological inflammation, and neurological disorders.

Unfortunately, this book is more dogmatic than it is educational. The author might be right overall. No one in this day and age can know for sure due to the sheer complexity of human physiology and the lack of studies adequate to really provide us the knowledge we need.

The author has a case he wants to make and he does so by providing only the information that supports his case and he leaves out pretty much everything else including any established facts that might contradict his arguments, or t

I received this advance readers copy from Goodreads First Reads. Yay for free books and thank you!

Perhaps I should apologize in advance, this is long and probably a bit of a tirade. Here's the good parts version: If you are concerned about gluten intolerance (not celiacs), your blood sugar levels, neurological issues or just think you are hooked on sugar and worry about bad for you carbs read this book.

I don't even know why I read this. Listened to it. Whatever. It's 1:12am. I actually finished this like two weeks ago anyway.

Found it on Overdrive and needed something for the commute. I thought nonfiction might make me smarter, more informed, what have you. Instead it scared the hell outta me.

We all knew sugar, carbs, gluten, bread, candy, soda, etc. are all bad for us physically. This book breaks down how carbs, and grains especially, are eating away at our brains, giving us diabetes, and ul

I admit I have a bias against health books: They are usually poorly written, bloated with patient testimonials, and the information could be better summarized in a good magazine article.

And that's true of Grain Brain, which I picked up after seeing an article about the link between carbs and problems in the brain, including dementia, Alzheimer's disease, anxiety and depression. Dr. Perlumtter recommends cutting down on carbs, especially ones containing gluten, and eating healthy fats to feed you

As with any diet book, and especially with this one, follow your doctors orders, listen to your body, and use common sense.

I have had gluten issues in the past, and several of the medical issues mentioned run in my family. I try to eat gluten free as much as possible, which really just translates into non-processed foods and whole fruits and vegetables.

That being said, this book is really a hate campaign against gluten. Carbs are not the devil. And the language used in this book is generalizing

This was a really informative book that definitely blew my mind in terms of the argument - fat and cholesterol are good? Really? But he's got the research to back up the claims, and it's very compelling. As a person who has followed a strict gluten-free diet for over 2 years I found the research and case studies on gluten sensitivity especially interesting, although it did wake me up that I need to rethink my gluten-free lifestyle in terms of also limiting the things that I have always allowed m ...more

I have been obsessed with this book for months now. I can't stop talking about it. It's all about how you can take control of the health of your brain (and your body) by removing gluten from your diet. I thought it would be hard, but it's actually the best thing I've ever done. I highly, highly recommend this fascinating book. It is both informational and practical.
tl;dr: quack sensationalist quack data-mining quack

Author claims that the source of almost all neurological illnesses/dementia is *not* due to genetics, but to diet. Author's father is 96 and demented off his gourd, so author obviously wants to assure self he's not doomed to the same fate.

This book is horseshit. He says that paleo-type ancestors never had alzheimers/dementia, though as far as I know, no one has ever found viable brain samples of paleo-era ancestors. He also seems to believe in

Grain Brain makes some important points, but in the style of a partisan propagandist aka politician. There is no balance to the arguments made and that's the reason why the readers have to be as mindful of the conclusions as readers of any books on ideology, religion or any occult sciences.

On the negative side, the author has pre-decided that he has hit on the eternal truth about the right eating and all else are wrong. While he provides proofs behind his theories in plenty (some definitely over

Dear Past Roya,

Over the past twelve months, I've noticed some new things. I've noticed that people are far more irritating than they were last year. That's fine, you'll get over it. I've noticed that I relate to Anxiety Cat memes a lot more than I'm comfortable with. This isn't okay, but it's not the worst thing ever. You are what you are (unless what you are is an axe-wielding psycho, in which case I strongly adv

I was already one of the converted; I follow the Paleo diet and thrive on it, after years of battle with candidiasis and other ills. The difference it makes in quality of life and the amount of energy I have is incalculable. To an outsider, it looks like a fad.

The basis contention of this book is that most of the medical ills of our age - from rashes and headaches to obesity, diabetes, and cancer - are caused by eating glutinous grains. For generations now we have believed cholesterol and fat to

It worked for me before I even heard of this book!

I went on a ketogenic diet (low-carb, high-fat) last year to lose weight and next thing I know, my chronic life-long depression and anxiety disappeared, I had more focus, more energy, more positivity in general. I had NO IDEA that a ketogenic diet would do this, but it did. I started to enjoy exercise for a change, which helped even more. My life was changed forever.

I'm giving this two stars because this book is quite dishonest in places. There is a great deal of good useful information, and this a significant amount of speculation presented in the guise of factual information.

I agree with the ideas that fat is good and carbs are maybe not so good.

The authors views on gluten are where the author fails to make a scientifically sustainable case. For example the author claims that in the 20th and now 21st centuries we have a plague of mental diseases due to gl

Dr. Perlmutter is a board certified neurologist and in this book he presents a thesis that food affects our brain health. He's a big proponent of the low carb ketogenic diet--high in fat--good fats--moderate protein, and low carb. However, my biggest takeaway are his prescriptions for improving brain health. He recommends increasing aerobic exercise, which has a strong correlation of maintaining brain health, even at a great efficacy than working the brain directly via mental works such reading ...more

My mom, sister, and brother, all have a neurological disease called dystonia. It involves their muscles (calf for sister, arm for brother, fingers and toes for my mom) tightening up involuntarily from time to time. It isn't life threatening but has definitely been a nuisance to all three of them. Each of their symptoms manifested when they turned 30 - which is two years for me. So I am trying to prepare myself for that possibility (although my other older sister is 32 and has no symptoms).

Grain Brain is a good book as far as re-educating people regarding food myths that have taken root in our culture, such as that grains are good for you, or necessary for fiber, or that eggs and cholesterol are evil. I applaud the author for the many studies he cites and for bringing these misconceptions to light.
There is a deep flaw in the book, however, and it is ludicrous: the author bends over backwards to prove his dietary recommendations but includes assertions based on the THEORY of evolu
In my case Dr. Perlmutter is preaching to the choir, and I did really appreciate the novelty of his approach, i.e., the effect of food (gluten/sugar/carbohydrates as a class) on brain deterioration and disease, rather than on our other organs and overall physical well-being.

The disappointments, which have been well-chronicled in other Goodreads reviews, include:
(1) an onslaught of cited studies which overwhelm the reader, and which may all not be sufficiently robust to pass scientific muster;

Grain Brain, by Dr. David Perlmutter, is a breath of fresh air. Great detail is given about how gluten, sugar, and other carbs cause inflammation, wreaking havoc on your hormones, blood sugar, brain, and waistline. Numerous examples are given of patients he treated with this program and they lost weight, or improved their labs dramatically, or overcame diagnoses like ADHD. Sleep habits and exercise are also covered as they have an effect on the brain and how it functions. I was not aware that le ...more

Can you live life without grain and sugar? The author will show you how and why. He provides much medical research evidence linking grain and sugar to Parkinsons, Alzheimers, dementia, and even mental illnesses like bi-polar. I was already familiar with much of the info. presented, but the cool thing about this book is that he has referenced all the original sources. So readers can investigate the claims for themselves.

First, let me tell you I am NOT a Dr. Oz fan, and the fact that this book was written by someone on his panel sort of left me skeptical about reading it. Seems there's a little too much sensationalism there. Also, a little background on me: I'm diabetic, diagnosed in January 2014, and was put on Paleo lifestyle (notice I didn't call it a "diet"?) to help combat issues with my A1C numbers.

So, there's that. Some people will tell you Paleo is extreme (and to be fair, some Paleo followers are extr

This is one of a new wave of books that challenges our eating habits. Dr Perlmutter is an advocate of the Low carb, high fat school of nutrition (ala Atkins, Jaminet, Taubes, Moore, et al). He is a neurologist though, and he details how a certain carb, Wheat, not only effects our endocrine and digestion systems, but most importantly our brains. Neuro diseases appear, to the author, to be influenced negatively by the consumption of carbs, especially wheat. He details this extensively. We are talk ...more

Absolutely astonishing. From type 3 diabetes (alzheimer's) to virtually every chronic disease and ailment of modernity (cancer, adhd, dementia,...), David Perlmutter presents a startling, well documented case about the dangers of grains, sugars, and starches in our modern diet. From doctors to mothers, this book should be read by everyone--your life could very well be saved by what you learn.

“Researchers have known for some time now that the cornerstone of all degenerative conditions, including brain disorders, is inflammation. But what they didn’t have documented until now are the instigators of that inflammation—the first missteps that prompt this deadly reaction. And what they are finding is that gluten, and a high-carbohydrate diet for that matter, are among the most prominent stimulators of inflammatory pathways that reach the brain.” 5 likes
