Alzheimer's disease has become nothing short of epidemic in the US. Could it be that some commonly eaten foods are the primary culprit? According to neurologist Dr. David Perlmutter, author of the book Grain Brain, your diet has major implications for your Alzheimer's risk.

Grain Brain has been on the New York Times Best Seller list for six months now, which is unusual for a health book. He has also been on a few PBS specials. Dr. Perlmutter is also the editor-in-chief of a brand new Harvard-based journal called Brain and Gut, slated to come out next year.

He came to the conclusion that brain dysfunction is rooted in a flawed diet, particularly our modern-day high-grain diet, after scouring the medical literature looking for clues to the underlying cause.

He'd grown weary of treating his patients' symptoms, and wanted to get to the bottom of the problem. As it turns out, the scientific literature is actually replete with information telling us that, yes, diet plays a crucial role in brain function. He says:

"What we've crystallized it down to now, in essence, is that diets that are high in sugar and carbohydrates, and similarly diets that are low in fat, are devastating to the brain.

When you have a diet that has carbohydrates in it, you are paving the way for Alzheimer's disease. I want to be super clear about that. Dietary carbohydrates lead to Alzheimer's disease.It's a pretty profound statement, but it's empowering nonetheless when we realize that we control our diet. We control our choices, whether to favor fat or carbohydrates."
High-Carb Diets Associated with 89 Percent Increased Risk for Dementia

As just one example, he cites research from the Mayo Clinic, published in the Journal of Alzheimer's Disease, which found that diets rich in carbohydrates are associated with an 89 percent increased risk for dementia. Meanwhile, high-fat diets are associated with a 44 percent reduced risk.

Clearly, with Alzheimer's disease now hot in the tracks behind heart disease and cancer as one of the top three killers in the US, we really need to pay attention to such findings.

"There is absolutely no treatment for Alzheimer's disease. And yet, according to Dr. Deborah Barnes, publishing in the journal Lancet Neurology, more than half the cases of Alzheimer's disease today  54 percent  could have been prevented had people gotten this information," he says.

Fortunately, even if you're already having "senior moments," you can turn back the clock, as it were. You can regenerate cells in your brain's memory center. This occurs through a process called neurogenesis.

According to Dr. Perlmutter, the evidence clearly shows that high-carb diets and elevation of blood sugar is directly related to shrinkage of your brain's memory center. And when your hippocampus your memory center shrinks, your memory declines.

"That is the harbinger for Alzheimer's disease," Dr. Perlmutter says. "It's the first place you look on a brain scan. But here is why we're having this conversation today: (1) it is preventable and (2) more importantly, it's reversible."
Saturated Fats Are a Critical Part of a Heart- and Brain-Healthy Diet

Dr. Perlmutter has been talking about the benefits of saturated fat for a long time. Conversely, for well over half a century, the media and a majority of health care officials have warned that saturated fats are bad for your health and lead to a host of negative consequences, including high cholesterol, obesity, and heart disease.

There's little doubt that this wholly inappropriate fat phobia has had a lot to do with our burgeoning Alzheimer's epidemic. Fortunately, the importance of these healthy fats is starting to become more widely recognized. One of the largest meta-analyses to date, included data from more than 600,000 people from 18 countries.

The study concluded that current evidence does NOT support guidelines that encourage low consumption of saturated fat for heart health. Saturated fats, which have the longest history of being (wrongfully) demonized, were in fact found to have NO adverse effect on heart disease risk.

"We've been led down the wrong road," Dr. Perlmutter says. "[Saturated] fat is your friend. You desperately need fat. You desperately need to have good cholesterol in your body. That war on cholesterol is a perversion of the science that was even used to tell us we should stop eating foods with cholesterol...

We know quite well that in elderly individuals, for example, those in the highest level of blood cholesterol have about a 70 percent risk reduction for becoming demented. These are the things that are good for the heart. They're good for the immune system. Cholesterol is the precursor of vitamin D, progesterone, estrogen, testosterone, and cortisol...This is probably one of the reasons why statin drugs are so damaging. You lower cholesterol, and you set the stage for things that are very, very worrisome."
Diabetes Doubles Your Risk of Alzheimer's

Dr. Perlmutter cites a study published in the Archives of Internal Medicine, which found that women who are given cholesterol-lowering statin medication have a 44 percent increased risk for becoming a type 2 diabetic. Diabetes, in turn, doubles your risk for Alzheimer's disease.

Our ancestral diet was very high in saturated fats and virtually void of non-vegetable carbohydrates. Today, not only do we eat tremendous amounts of carbohydrates, these carbs are refined and highly processed. In the last decade, we've also shifted over to genetically engineered grains and sugar (GMO sugar beets and corn).

At present, you have close to a 50/50 chance of developing Alzheimer's disease if you live to be 85 years old, according to Dr. Perlmutter. His mission is to radically shift those odds, by giving people the information they need to avoid being one of the unlucky ones destined to die without your mental faculties intact.
Alzheimer's Is Directly Related to Elevated Blood Sugar Levels

A study published in the New England Journal of Medicine in August 2013 demonstrates that even mild elevation of blood sugar—a level of around 105 or 110—was already dramatically associated with an elevated risk for becoming demented. Dr. Perlmutter believes it's very important for physicians to become cognizant of this link, and to stop downplaying the risks associated with even mildly elevated blood sugar.

If your fasting blood sugar is even mildly elevated (over 95 mg/dl), it's time to address your diet to lower it. Dr. Perlmutter makes a very important point here, noting that "normal" blood sugar really should not be the same as the average. It should be the optimal or ideal level. You do not want to be right smack in the middle "average" when the population sample is severely diseased!

So what is an ideal fasting blood sugar level? Dr. Perlmutter suggests that anything over 92 or 93 is too high. He believes the ideal fasting blood sugar level is around 70-85, with 95 as the maximum. If you're fat adapted, there's no reason to shun even lower fasting blood sugar levels. According to Dr. Perlmutter:

"It really depends on whether you have adapted your body to burning fat. People who have been on a high-fat, low-carb diet are able to tap into body fat as an energy resource. They've undergone a change called keto-adaptation. It means they're burning fat and they can get by with much lower blood sugar because they're burning fat and don't need to worry about blood sugar as much.

This notion that your brain needs sugar is really old news as well. Fat, specifically ketones, which your body produces by metabolizing your fat, is now called a 'brain superfuel.' There is even a pharmaceutical product; a medical food that you can write as a prescription, which raises the level of ketones or fat in the bloodstream of patients, offered up now as a treatment for Alzheimer's disease. Who knew? The point is the brain loves to burn fat. That's what we have to shift it over to..."
Intermittent Fasting Can 'Reset' Your Body to Burn Fat Again

Intermittent fasting, which can help jump start your body into burning fat instead of carbs as its primary fuel. In his book, Grain Brain, Dr. Perlmutter also starts off the intervention section with a period of fasting, which can be viewed as pressing the Reset button. He's particularly aggressive about it in patients who are insulin/leptin resistant.

keeping your fasting insulin level below 3. The so-called normal, however, is anywhere from 5-25 microU per mL. This despite the fact that the upper edge of this "normal" clearly indicates you have a problem with insulin resistance! Again, you do not want to be average here. You want your insulin/leptin levels to be ideal or optimal for health and disease prevention.

"If somebody has an insulin level of 26, they are in trouble. They need a lot of work. They need to fast. They need to drop the carbs. They need to add back the good fat. They need to add in some anti-glycating agents like benfotiamine and resveratrol. This is what works. This is what reduces their risk of converting to diabetes, and therefore has a huge role to play in protecting their brains," Dr. Perlmutter says.
Eat the Right Types of Fat.

The type of fat you eat naturally makes all the difference in the world. Avoid all trans fats or hydrogenated fats that have been modified in such a way to extend their longevity on the grocery store shelf. This includes margarine, vegetable oils, and various butter-like spreads. Sources of healthy fats to add to your diet include: Avocados Butter made from raw, grass-fed organic milk Raw dairy Organic pastured egg yolks
Coconuts and coconut oil (coconut oil actually shows promise as an effective Alzheimer's treatment in and of itself) Unheated organic nut oils Raw nuts, such as pecans and macadamia, which are low in protein and high in healthy fats Grass-fed meats

Our genome takes 50,000 to 70,000 years to make significant changes to adapt to new environments and adapt to new foods. We are instructing our genome with this perverted information by giving our genomes signals from high levels of processed foods and carbohydrates.

Aerobic exercise is a powerful player. It can help alter your gene expression to code for things that will result in a longer and healthier life. Exercise also reduces free radical production and inflammation, both of which are drivers for chronic disease. More directly, exercise has been shown to turn on a brain growth hormone called BDNF, which stands for "brain-derived neurotrophic factor." BDNF codes for your brain's ability to both repair itself and grow new brain cells. The latter occurs through a process known as neurogenesis.

Dr. Perlmutter says when he was in medical school, he was taught that once a brain cell dies, that's it; there's no going back. This view has been completely demolished by more recent research, which clearly demonstrates that your brain can both regrow neurons and even rewire itself to "work around" damaged areas. As for the type of exercise, Dr. Perlmutter recommends high-intensity interval training (HIIT), which provides you with the equivalent of two hours-worth of conventional aerobic exercise in just 20 minutes. I suggest the Peak 8 routine!

Dr. Perlmutter's Grain Brain program also includes a number of other recommendations, including but not limited to:
Turmeric, for its anti-inflammatory potential and ability to activate BDNF, the hormone involved in brain health and neurogenesis.
Monitoring your vitamin D level. Dr. Perlmutter recommends maintaining an optimal level of around 70-90 nanograms per milliliter (ng/ml) year-round.
Optimizing your gut health by reseeding your gut with beneficial bacteria (probiotics). One recent study cited by Dr. Perlmutter correlates the risk for becoming an Alzheimer's sufferer in various countries; countries that have a lot of parasites in the gut as a marker of poor hygiene actually had the lowest risk of Alzheimer's. Countries where there were no parasites in the gut or very few, courtesy of superior hygiene, had a significantly higher risk of Alzheimer's.

It's important to avoid antibiotics. Non-breastfed babies are more prone to ear infections, which can easily set them up for excessive antibiotic use. Do your homework before demanding antibiotics. Eating CAFO meats will also provide you with traces of antibiotics in each bite. All these antibiotics kill beneficial bacteria, and the resulting chronic poor gut health can place your brain at significant risk.
Measuring your gluten sensitivity with a Cyrex [Array 3] test. Research suggests gluten can play a damaging role by the changes it imparts on your microbiome, the bacteria in your gut. But gluten can also wreak havoc with your neurological health via the inflammation it causes. Non-celiac gluten sensitivity may involve 30 to 40 percent of the population, Dr. Perlmutter says, and according to work done at Harvard by Dr. Alessio Fasano, it may even affect every single human being.
The reason for this is because gluten, a protein found in wheat, barley, and rye, has significant effects on your gut cells, which leads to the production of a chemical called zonulin. Zonulin enhances inflammation and tends to make your gut porous and leaky (leaky gut syndrome). Dr. Fasano discovered that it can also make your blood-brain barrier leaky, allowing foreign proteins to migrate into your brain, where they clearly do not belong.
Fecal transplantation, in cases of severe neurological dysfunction where poor gut flora appears to be a contributing factor. Your microbiome is critical for multiple reasons, including regulating the set point of inflammation, producing neurotransmitters like serotonin, and modulating systems associated with brain function and brain health. This form of therapy is now the standard of care for life-threatening C. difficile infections.
A Brain Healthy Diet Will Benefit All Neurological Disorders

A high-fat, low-carb ketogenic diet is not just for the treatment of Alzheimer's and other forms of dementia. It's the right diet for ALL brain-related disorders, including but not limited to:
Parkinson's disease (according to Dr. Perlmutter, the rate at which a Parkinson's patient will decline perfectly correlates with the elevation of their blood sugar)
Seizure disorders like epilepsy,
Autoimmune disorders like multiple sclerosis (MS),
Attention deficit hyperactivity disorder (ADHD)
Core Ingredients of a Brain-Healthy Diet

Dr. Perlmutter emphasizes the importance of favoring above-ground colorful vegetables, as these contain less starch, which your body breaks down into simple sugars. Healthful options include kale, chard, collards, broccoli, and spinach. These also contain plenty of healthy fiber you really do not need grains to meet your fiber requirement.

Dr. Perlmutter also recommends cooking your food as little as possible. The more food you can eat raw, the better, especially as it relates to your microbiome. Add fermented vegetables, to promote healthy bacteria in your gut, and sprouted seeds.
Choosing meats that are grass-fed and that are organically raised.
Wild fish not farm raised, antibiotic-treated fish, pasture-raised chicken, and farm raised or pasture-raised eggs.

gymdandee, very sorry to hear of your losing your mom at such a young age.  Terrible!  I lost my mom in my 20's and life was never the same so can't imagine losing her as a child.  And now that I'm a mom, the fear of my boys without a mom makes me literally sick to my stomach.  Good motivation to be a good girl!  Thank you for that reminder.  Really, I like to look good but the reason you stated is EXACTLY why I need to be mindful.

Where can I find specifics on the ketogenic diet? I have looked and looked.  Do I just eliminate ALL carbs?is there a number I should be aiming for?  Is almond milk okay?  What about artificial sweeteners? Do fiber and sugar alcohol in foods reduce the carbs?  Adkins says it does.

Have you read the book Grain Brain By Dr. Perlmutter?
Also check out the Paleo Diet!

You should never omit all carbs.  People are very confused by food categories, as evidenced by this post.  All fruits and vegetables are carbs, and this is where most of our diet should come from.  Whole grains are combinations of carbs and protein, as are beans.  These are also a great chunk of a modern human diet.  The paleo diet doesn't exist except in the imagination, since the people on it don't have a clue as to what hunter gatherers really ate, which was certainly not a bunch of meat they had trouble catching without modern technology.  They always focus on the hunting while forgetting that mostly they ate what they gathered.  What's become known as "carbs" are simple carbs, which is a very small category among carbohydrates in general.  As to the question by Carbb, artificial sweeteners have been associated with many diseases and are far worse if eaten a lot than sugar.  Fiber is from carbohydrates; there is no or little fiber in protein.  Beans are so good for you because they contain fiber from the carbohydrate content so you can digest the protein, but of course many have problems digesting beans and you have to know how to properly prepare them to avoid that.  Sugar alcohol is an example of the simple carbs that people are warning about.  This includes sugars, white flour, and the like.  Avoid all fad diets, because every one of them eventually turns out to be either not effective or downright dangerous over time -- much like most medications!  In other words, be practical, not dogmatic, and read books, not just websites.  Then divide by two.

By the way, not all sugars are the same, either.  Some break down very quickly (simple sugars) and some break down more slowly (complex sugars)  -- the former are cane sugar, while examples of the latter are sprouted grain sugars such as rice malt and barley malt.  Honey is in the middle -- some advocate it, some don't, but if you do eat it try to eat raw honey, not the highly processed stuff.  Life's complicated, folks, and what we don't know far outstrips the little we do.  Then you have to figure out how much is paid for by advertisers and how much is dedicated independent research and how many people were actually studied and for how long, since these studies are very expensive to do with human beings.  We're collecting a lot of information right now, but we'll all unfortunately be dead before these issues reach any consensus.

Gym, I was responding to Carbb, not your original post which has a lot of good food for thought in it.  I should have been more specific.  Sorry about that.
