The fundamental
take home here is that we need to protect our brains with plenty of healthy
fats. High on that list is a breakfast
of poached kippers and a large serving of fermented vegetables such as sauerkraut
or kimchee. Better still make your own
by fine shredding everything you like including carrots, hand mashing to
release enough fluid and add a little salt to taste. Two weeks later it will be well fermented and
be ready for the fridge.
What it
particularly interesting about all this is that fermentation makes it all soft
including the carrots. You could eat all
this without a set of teeth to help you and you would be very healthy. We have gotten away from all this because it
was mostly a food of older people in the
first place.
You see my
point.
What Grain Is
Doing To Your Brain

Drevitch, Contributor
It’s tempting to call David Perlmutter’s dietary
advice radical. The neurologist and president of the Perlmutter Health
Center in Naples, Fla., believes all carbs, including highly touted whole
grains, are devastating to our brains. He claims we must make major changes in
our eating habits as a society to ward off terrifying increases in Alzheimer’s
disease and dementia rates.
And yet Perlmutter argues that his recommendations
are not radical at all. In fact, he says, his suggested menu adheres more
closely to the way mankind has eaten for most of human history.
What’s deviant, he insists, is our modern diet.
Dementia, chronic headaches, depression, epilepsy and other contemporary
scourges are not in our genes, he claims. “It’s in the food you eat,”
Perlmutter writes in his bestselling new book, Grain Brain: The Surprising Truth
About Wheat, Carbs, and Sugar – Your Brain’s Silent Killers. “The origin of brain disease is in many cases
predominantly dietary.”
Perlmutter’s book is propelled by a growing body of
research indicating that Alzheimer’s disease may really be a third type of
diabetes, a discovery that highlights the close relationship between lifestyle
and dementia. It also reveals a potential opening to successfully warding
off debilitating brain disease through dietary changes.
Perlmutter says we need to return to the eating
habits of early man, a diet generally thought to be about 75% fat and 5% carbs.
The average U.S. diet today features about 60% carbs and 20% fat. (A 20% share
of dietary protein has remained fairly consistent, experts believe.)
Some in the nutrition and medical communities take
issue with Perlmutter’s premise and prescription. Several critics, while not
questioning the neurological risks of a high-carb diet, have pointed out that
readers may interpret his book as a green light to load up on meat and dairy
instead, a choice that has its own well-documented cardiovascular heart risks.
“Perlmutter uses bits and pieces of the effects of
diet on cognitive outcomes — that obese people have a higher risk of cognitive
impairment, for example — to construct an ultimately misleading picture of what
people should eat for optimal cognitive and overall health,” St. Catherine
University professor emerita Julie Miller Jones, Ph. D., told the website FoodNavigator-USA.
Grain Brain does delve deeply into the negative
neurological effects of dietary sugar. “The food we eat goes beyond its
macronutrients of carbohydrates, fat and protein,” Perlmutter said in a recent
interview with Next Avenue. “It’s information. It interacts with and instructs
our genome with every mouthful, changing genetic expression.”
Human genes, he says, have evolved over thousands of
years to accommodate a high-fat, low-carb diet. But today we feed our bodies almost
the opposite, with seemingly major effects on our brains. A Mayo Clinic study
published earlier this year in the Journal of Alzheimer’s Disease found that
people 70 and older with a high-carbohydrate diet face a
risk of developing mild cognitive impairment 3.6 times higher than those who follow low-carb regimens. Those
with the diets highest in sugar did not fare much better. However, subjects
with the diets highest in fat were 42% less likely to face cognitive impairment
than the participants whose diets were lowest in fat.
Further research published in the New England
Journal of Medicine in August showed that people with even mildly elevated
levels of blood sugar — too low to register as a Type 2 diabetes risk — still
had a significantly higher risk of developing dementia.
“This low-fat idea that’s been drummed into our
heads and bellies,” Perlmutter says, “is completely off-base and deeply
responsible for most of our modern ills.”
Turning to
Nutrition, Not Pills
This fall, the federal government committed $33.2
million to testing a drug designed to prevent Alzheimer’s in healthy
people with
elevated risk factors for the disease, but “the idea of lifestyle modification
for Alzheimer’s has been with us for years,” Perlmutter says, and it’s
cost-free.
The author hopes his book and other related media on
the diet-dementia connection will inspire more people to change the way they
eat. “Dementia is our most-feared illness, more than heart disease or cancer,”
Perlmutter says. “When you let Type 2 diabetics know they’re doubling their
risk for Alzheimer’s disease, they suddenly open their eyes and take notice.
“People are getting to this place of understanding
that their lifestyle choices actually do matter a whole lot,” he says, “as
opposed to this notion that you live your life come what may and hope for a
pill.”
As we learn more about the brain’s ability to maintain
or even gain strength as we age, Perlmutter believes, diet overhauls could
become all the more valuable.
“Lifestyle changes can have profound effects later
in life,” he says. “I’m watching people who’d already started to forget why
they walked into a room change and reverse this. We have this incredible
ability to grow back new brain cells. The brain can regenerate itself, if we
give it what it needs.”
What it needs most of all, Perlmutter says, is
“wonderful fat.” There’s no room in anyone’s diet for modified fats or trans
fats, he says, but a diet rich in extra-virgin olive oil, grass-fed beef and
wild fish provides “life-sustaining fat that modern American diets are so
desperate for.”
Too few of us understand there’s “a big difference
between eating fat and being fat,” he says. People who eat more fat tend to
consume fewer carbs. As a result, they produce less insulin and store less fat
in their bodies.
Change We Ought
to Believe In
Changing minds, however, is an uphill climb. “The
idea that grains are good for you seems to get so much play,” he says. “But
grains are categorically not good for you,” not even whole grains.
“We like to think a whole-grain bagel and orange
juice makes for the perfect breakfast,” Perlmutter continues. “But that bagel
has 400 calories, almost completely carbohydrates with gluten. And the hidden
source of carbs in this picture is that 12-ounce glass of fresh-squeezed orange
juice. It has nine full teaspoons of pure sugar, the same as a can of Coke.
It’s doing a service with Vitamin C, but you’ve already gotten 72 grams of
carbs.
“It’s time to relearn,” he says. “You can have
vegetables at breakfast – the world won’t come to an end. You can have smoked
salmon, free-range eggs with olive oil and organic goat cheese and you’re ready
for the day. And you’re not having a high-carb breakfast that can cause you to
bang on a vending machine at 10 a.m. because your blood sugar is plummeting and
your brain isn’t working.”
Changing one’s diet is a challenge, he
acknowledges. Giving up the gluten found in most carbs makes it even
tougher. “The exact parts of the brain that allow people to become addicted to
narcotics are stimulated by gluten,” Perlmutter points out. “People absolutely
go through withdrawal from gluten. It takes a couple of weeks.”
But the change is worth making, he says, at any age.
“Nutrition matters,” Perlmutter says. “The brain is
more responsive to diet and lifestyle than any other part of the body and until
now it’s been virtually ignored. We
load up on medications when our mood is off, we hope for an Alzheimer’s disease
pill when we get older. I submit that we need to take a step back and ask, ‘Is
this really how we want to treat ourselves?’”

What Gary says here is absolutely correct. Modern wheat is a genetically modified organism--the "ancient grains" like quinoa, millet, amaranth, sorghum, teff and kamut don't have gluten, and neither does brown rice. If you stick to those, fruits (not juice) and vegetables, canned fish like salmon, herring and sardines (all are wild caught), poultry and some beef, tubers, nuts and seeds, you'll be healthy like me...54, 6'2", 180 lbs., NO health problems, brain sharper than ever.
