My wife Kate had long been suffering with, what I referred to as, an irritable bowel condition for quite some time. Her gastroenterologist after a colon exam, told her to eat a lot of “Bran Buds” every day and consume a daily fiber drink, along with a laxative. Upon following this advice, her condition deteriorated. She entered into phases of severe pain and sleeplessness, leading to extreme fatigue.

We knew this wasn’t working and needed to try something different.

After a few days on gluten-free, low-carb diet, her symptoms disappeared completely! Not only that, but her GP has previously put her on Crestor, and she is now off that too! She also has solved the restless sleep condition entirely.

In Grain Brain, I found a book that had resonated with what I had for so long believed to be the truth about optimal health. Prior to reading, I had suffered from severe headaches since I was eleven.

Once I stopped eating gluten, lowered my carb intake, and increased my fat intake, my condition suddenly began to improve! Now, I rarely get headaches, and if I do they go away quickly. I also lost weight and my overall mood has improved. I’m very happy with my results!

When I was in my early 20s I was stricken with an extremely severe neurological disorder that destroyed my career as a cosmologist (a professional astronomer who studies the general nature and origin of the universe). My condition deteriorated very badly, but in 1984 I underwent a special test for food allergies.

I now eat approximately 20 unprocessed foods (leading to a gluten and grain-free diet) as my entire diet and I drink distilled water as my only fluid; I would estimate that my health is now approximately 100 times better, and that, at 65 years of age, my hearing is better than when I was a teenager! My night vision is better, my problem with obesity is gone, and many other symptoms have either disappeared or vastly improved.

Reading Grain Brain changed my life forever.

For the past five years, every three months, I have received botox or myoblock injections to treat my cervical dystonia. Though I received the injections, my head still shook on occasion. On February 17, 2014, I started on a gluten-free, ketogenic diet, in hopes I would be treating my cervical dystonia. With this diet, the head shaking is minimal. Today, I will no longer need to see my neurologist. The diet did not cure my cervical dystonia but made it livable without botox/myoblock injections. My conclusion is diet and sleep are the best treatment.

Thank you for your research and for writing Grain Brain. I have been gluten-free for four weeks now and have lost 8 pounds. These were 8 stubborn pounds that I just could not dislodge for several years now – even with healthy eating and daily exercise. Your book (and now my scales) has taught me that gluten was the culprit! Overall, I feel much better and my mind seems clearer. Short-term memory has been a challenge in my 50’s, and I now know that having “Grain Brain” was the cause! I am hoping to see an improvement in this area given more time on my new gluten-free food plan.

My wife and I are 60 years old. We saw your program, BRAINCHANGE, in March 2014 and subsequently purchased Grain Brain and made the dramatic shift to a gluten-free, grain-free approach to eating. We emptied the pantry of any gluten-related items. The major improvement is that, after three months, I no longer take a daily iron supplement and have an increased feeling of energy. My iron and ferritin readings are now in the normal range.  

Both of us have experienced an amazing new sense of clear-headedness. We know how it feels to be “fuzzy headed” or have a “foggy brain” and those feelings have vanished. Even though we are very fit and regularly exercise, we both lost some more weight as a result of the reduction in carbs and we increased our protein.

My mother had and died with Alzheimer’s and I am willing to bet that this approach to eating will help me significantly reduce my chances of getting the disease. I also believe it will significantly increase my chances of watching my grandchildren grow and be part of their lives for a very long time.

My mother died 10 years ago of undiagnosed, untreated leaky gut. Even though she had obvious problems, the GI doctors had no idea what was wrong with her. It was a nightmare watching her suffer, and driving her to countless doctor’s appointments only to walk away empty-handed. She had so much pain. She was on Oxycotin and also massive amounts of IV antibiotics to treat diverticulitus. Her poor gut was a total mess. We finally got her to a surgeon who read the earlier scans, which were taken and read by the GI specialist, to find that she needed immediate surgery. The surgeon actually asked us: “Did the GI doctor think this was OK?”.

Mom was too weak to have an operation, and could no longer digest food, so they put a central line in her and fed her liquid food to build up her strength. This went on for several weeks and the day before her surgery, so was brought to the hospital with a 105 degree fever. During her emergency operation, she suffered a heart attack, her intestines were falling apart in the surgeon’s hands, and could not be repaired. As a result she ultimately died of sepsis.

This was such a nightmare for our family and completely avoidable. Now 3 of her 4 children are having symptoms like she did. Two of us went to GI doctors, to find that they have learned nothing in the past 10 years. We both then went to functional doctors, who were enormously helpful. We were diagnosed with leaky gut and took the time to learn about it.  We changed or diet (gluten-free and dairy-free), started taking supplements, and are doing much better.

It is amazing to me that gluten can wreak such havoc in the body, and literally kill us if we don’t take steps to eliminate it from our diet.  If only we knew then what we know now.

I quit eating wheat and gluten 11 years ago due to a positive test for sensitivity for both. Prior to that, I had constant bloating and “mystery” itches that no doctor could diagnose.

As soon as I quit wheat and gluten, the itch was gone! It would only come back when I ate food crossed-contaminated by wheat/gluten!

My whole life has changed for the better. After removing wheat and gluten, I immediately lost 15 pounds! Did my energy return? Let me just say WOW, did it ever! I am 63 years young and my younger friends and family can barely keep up!

I recently decided to go on a very low carb program, and I stick to 60carbs/day or less. I feel even better than I did before, and even lost an extra ten pounds! Also, I would like to add that I have run a support group for people with Tinnitus for 16 years now and I believe that wheat/gluten does have a negative effect on tinnitus sufferers! Sure does with me!

Will P.

My name is Will. I’m 42 years old and have been diagnosed with epilepsy since the age of 14. Additionally, I have been diagnosed with hypothyroidism and stomach ulcers. Over the past 5 years my health has been deteriorating steadily. My weight was up to 355lbs as well. My wife was getting very concerned that I may not be with her much longer. When she read a book about gluten and its effects on the body, she realized almost immediately that I fit into either the celiac or gluten intolerance category (we still aren’t sure which one).

I read the book after she did and we decided to try going without gluten for two weeks to see if there was any truth to it.

What a difference this has made. I was on medication for my stomach issues (heartburn and stomach upset), thyroid medication, and Dilantin and Tegratol for my epilepsy. Not only have my aches and pains subsided, but I am no longer taking ANY medication. I have been off my stomach and thyroid meds for at least 4 months and I feel great. I have now been off my epilepsy meds for 6 weeks with no seizures or any repercussions what so ever.

It’s wonderful to hear of the myriad conditions that were solved for Jesse just by eliminating gluten and wheat from his diet. – Dr. Perlmutter

In 2006, I realized that wheat was affecting my health. Still, I kept playing the “on again, off again” game of eliminating wheat for long periods of time, only to find myself binging on it a short while later. I began to notice that the periods that I experienced suffering were lasting longer after each binge.

The final straw came this past January. My suffering was so horrible I almost checked into the hospital. I had horrible, constant migraine headaches that caused my to stay in bed for hours during the day. I was blowing chunks of mucus from my nose every two minutes. My sinuses were swollen. My head was hot and tingly. This went on for six weeks.

Fortunately, I saw your PBS special. I immediately bought a copy of Grain Brain. After your special was over I took your advice and bought some eggs (I was eating vegan at the time). I felt so sick but I managed to drag myself out of bed and take public transportation to a food store that sold cage-free, vegetarian-fed eggs. I went, totally, gluten-free. My condition improved, remarkably. The migraines are gone. My sinuses cleared. I lost weight, naturally.
