I have a history of Alzheimer’s  disease in my family, as it has afflicted my mother, sister and several aunts. In my own life, I recently noticed that my recall for nouns is slipping and I couldn’t turn up the simplest of words. I decided to stop eating gluten. After two gluten-free weeks, I had a big bowl of pasta, got in my car and realized I couldn’t find my way to tai chi class. When I managed to get there I was unable to follow the form. It was really frightening. Later, I tried with a bowl of cereal and something similar happened. I tried following this elimination-style diet 3 more times with similar results. Now, I fully follow a gluten-free, low-carb diet. Two years after all that, and I can recall most words with only the occasional lapse in time.  I am so grateful.

Grain Brain was one of the first books I read when diagnosed with deadly brain cancer, and I truly believe it saved my life.

I was diagnosed with “terminal”, highly malignant brain cancer in 2013. I embarked on a highly therapeutic ketogenic diet to starve my cancer and boost the mitochondria of my healthy cells, with special help from my own “FARM”-acy. Today, three years later, not only am I alive, but thriving as my scans show no cancerous processes at all. An added benefit has been the complete reversal/elimination of polycystic ovary syndrome, Hashimoto’s Thyroiditis, breast fibroids, joint pain/arthritis, seasonal allergies and a very healthy amount of weight loss. My blood work shows massive reductions in inflammation markers, as well as blood sugar!

I’m sharing my journey with that hope that it will inspire others to follow this lifestyle protocol.

At the age of 31 I decided I was sick of being overweight with terrible IBS, rotting teeth and aching joints. I took it upon myself after, getting kicked off a theme park ride for being too big, to change my life around. I started researching different diets, beginning with Pete Evans’ Paleo Way program and mostly because of the interview with Dr. Perlmutter. After one year on a paleo lifestyle, I lost 50kgs and I’ve never been healthier! I am absolutely the model of health now. I surf with my 3 children and absolutely love living a healthy lifestyle. I couldn’t imagine eating any other way now!

Recently, I read Brain Maker. I quickly put the whole family on probiotics. The biggest change for me was I now no longer have migraines or psoriasis! That is what I wanted to share. I tell everyone about the book and encourage them to take a probiotic.

I am 85-year-old female, a retired nurse, and have followed Dr. Perlmutter since his very first book.

In 2005 I needed a cardiac cath. In 2006 I was diagnosed with MGUS and in 2007 I was diagnosed with Polymyalgia Rheumatica and Temporal Arteritis. These experience were my awakening. It dawned on me there was something wrong with the way I was living, eating, etc. I studied the cause of inflammation and knew I must go completely gluten-free, so I did. Beyond that, I am also dairy-free and regularaly fill my system with prebiotics and probiotics. I monitor my blood sugar to experiment with what I can eat without raising my BS above the limits. In all these years, I have not had a recurrence of my cardiac problems, nor PM and TA, and I attribute this entirely to these changes.

My whole life, all I’ve known is sickness. I started having regular nausea in junior high, along with vomiting and diarrhea. At age 29, I was 98 pounds and missing a lot of work. On top of that, I suffered from migraines. I worked in hospitals and had to go to emergency rooms to get IVs that would put me back on my feet.

Now I’m 55 and have been off gluten for four years. I have no more vomiting, food tastes better, and I am a normal weight of 120 pounds. I also have more energy. When I was eating gluten, I could not eat dairy; I am now able to tolerate butter and hard cheese. This change has truly changed my life!

I really appreciate Madelyn’s idea of a keepsake. Having an item like that keeps you grounded and allows for important reflections. – Dr. Perlmutter

I’m a 68-year-old woman who has been overweight for over 25 years. I have a family history of high blood pressure and stroke, and have suffered from various unknown food allergies and sensitivities, which erupted in hives and doctors called “chronic urticaria of unknown idiopathy”.  For years I carried an EpiPen in case my face or lips began to swell with hives, and I swallowed more antacids and antihistamine drugs than I care to remember. And yet, nothing worked, and drugs were the only things my medical doctors offered as relief.

After adopting a gluten-free diet at age 42, I find myself in the healthiest state of my entire life.

The results:

  • All IBS symptoms have disappeared.
  • I’m nearly pain-free from arthritis.
  • My monthly cycle is a non-issue for me now, no more illness and depression every month.
  • I get very few bugs, colds and coughs – which, with three kids, is no mean feat.
  • I’m more creative in the kitchen, I really taste and appreciate my food more than I ever did.
  • I buy my food seasonally (making my food bill cheaper), and I question the sourcing of what I buy a lot more – is the meat from grass-fed livestock, have the apples been sprayed with toxic chemicals, etc.?
  • I also struggle to eat anything really sweet (and I NEVER EVER thought I’d say that!!!) – once you cut most refined sugar out of your diet, it truly changes your taste buds – for the better!
  • I don’t get energy dips anymore, no more mid-morning or mid-afternoon slumps which means I’m more productive and I don’t reach for the sugary fixes.

At age 43, after a lengthy career as a pastry chef, I began to experience pains across my body. I went down the conventional route with my GP and saw a specialist, who diagnosed me first with osteoporosis and, later, Anklosing spondylitis. Injections and tablets didn’t help me, but, being a chef, I knew food had to be the key. I discovered I have the Hla-b37 gene and klebsiella bacteria in my gut. Now I know I have to avoid starches to remain

Two years ago, at age 36, I was diagnosed with Multiple Sclerosis. I was devastated. I sought out the help of a nutritionist, who, before she even met me, told me that I should probably go gluten free. If she had not said this to me, I am convinced that I would, by now, have suffered multiple relapses.

I immediately quit eating gluten. I noticed that I had more energy, I was thinking more clearly. My digestive system seemed to work, causing me to realize that, in fact, I could not remember a day of my life that it DID work well. I could think….and I realized that I never remembered a day when I didn’t feel foggy and tired. I lost 27 pounds in about 6 weeks…and the weight has NEVER crept back up on me. I had been so sick for the entire 36 years of my life that I did not know what “wellness” felt like until I cut gluten out of my diet. Still, I had lingering doubts: would this be enough to help me achieve brain health?

Then I found Grain Brain, and after that I found Brain Maker.  The principles taught in these books have changed my life. Going gluten-free was an immediate fix for me, I felt better very quickly. The concepts from Brain Maker came more gradually. I started eating fermented foods.  I learned that, if I had problems with gluten, I should probably be dairy-free, too.  I cut dairy out of my diet.  I eat as many vegetables as I can squeeze into a day.  I learned that my kitchen was the place where I was going to get well…and not in a neurologist’s office.  Food truly has become my medicine.  Did I mention that I am not at all affected by my MS to date?

I started eating fermented foods. I learned that, if I had problems with gluten, I should probably be dairy-free, too, so I cut dairy out of my diet. I eat as many vegetables as I could squeeze into a day.  I learned that my kitchen was the place where I was going to get well, and not in a neurologist’s office. Food truly had become my medicine. It should thus come as no surprise for me to mention that I am not at all affected by my MS (to date).
