A
distinct highlight of the 1st Annual Nutritional Ketosis and
Metabolic Therapeutics Conference in Tampa, FL, January 28-30, 2016, was a
presentation, “Hyperketonemia for Alzheimer’s Disease – A Case Report,” by Dr.
Mary Newport. Strictly by chance, I was privileged to have had supper with Dr.
Newport two days earlier.
Dr. Newport’s presentation was both
professional and very personal. It was the story of her 13-year travail
supporting the course of treatment of her husband’s Alzheimer’s disease (AD)
and how she learned about supplemental ketones as an adjunctive therapy. Her
talk received a sustained standing ovation. Dr.
Newport documented the story with, “What If There Was a Cure for Alzheimer’s
Disease, and No One Knew?” Google it.
“Brain cells, specifically neurons,”
Dr. Newport wrote, “are very limited – more limited than other cells – in what
kinds of fuel they can use to function and stay alive. Normally, they require
glucose (sugar), but they can also use ketone bodies.” “In Alzheimer’s
disease,” she continues, “the neurons in certain areas of the brain are unable
to take in glucose due to insulin resistance [IR] and slowly die
off, a process that appears to happen
one or two decades before the symptoms become apparent” (my emphases).
Note the similarity here to Insulin Resistance in Type 2 Diabetes.
“If these cells had access to ketone
bodies, they could potentially stay alive and continue to function,” she
reasoned. However, she noted, “Humans do not normally have ketone bodies
circulating and available to the brain unless they have been starving for
a couple of days or longer, or are consuming a ketogenic (very low
carbohydrate) diet, such as Atkins.” Ergo, unless we’re starving, or
strictly dieting such that we are in ketosis, or fasting, AS WE AGE, EVERYONE IS AT RISK of “starving” their brain. This alone, it struck me, constitutes a
rationale for supplementing with ketones.
So, what are ketones, aka ketone
bodies and ketoacids? They are products of the metabolism of medium chain
triglycerides (MCTs), which break down to fatty acids and ketone bodies. MCTs
are specific saturated fats, available commercially in oil form and composed of
caproic and caprylic acid (C6 and C8 carbon chain compounds). What is unique
about MCTs is that they are metabolized differently from other saturated fats.
They go immediately to the liver, and are used there directly for energy.
Other saturated fats, the long chain fatty acids (LCFAs), are absorbed by the
lymph system and circulated throughout the body, with some being used to fill
your fat cells (stored, not burned)!
The most common food product
containing MCTs is coconut oil, now
widely available in grocery stores. Refined coconut oil is about 60% medium
chain fatty acids (MCFAs), 30% LCFAs, 8% MUFAs and <2% PUFAs. It
contains no cholesterol but contains omega-6 fatty acids and virtually no
omega-3s. So, Dr. Newport says, if you plan to get your supplemental ketones
with coconut oil, she stresses that since “it contains no omega-3 fatty acids, it is very important to
eat salmon twice a week or get enough omega-3 fatty acid from other rich
sources such as fish oil capsules…” to correct your omega-6, omega-3 fatty acid
balance!
Another source of MCTs is palm kernel oil. Dr. Newport relates,
that “…after coconut and palm kernel
oil, the food that medium chain triglycerides are most concentrated in is human
breast milk.” So, it must be good for us, right?
Products comprising 100% MCT oil are also available in some health food
stores and are easily obtainable online.
But who knew? As Dr. Newport laments,
the benefits of MCTs as a
therapeutic protocol for the treatment of mild cognitive impairment or
incipient AD, or earlier as a PROPHYLACTIC strategy, are little known
and less recognized and/or appreciated. Dr. Newport herself unearthed it
while researching drugs prescribed for her husband. She found another drug in which, in a pilot study,
some subjects “improved on memory testing
with the very first test.”
And she found that “the promising ‘ingredient’ in (that drug) was simply MCT oil, and that a dose
of 20 grams (about 20 ml or 4 teaspoons) was used to produce these results.”
Translated to coconut oil (60% MCTs), Dr. Newport estimated that her husband
“would need to take 35 grams or just over two tablespoons (about 35 ml or 7
level teaspoons) of coconut oil.” How did this all work out? The results will
be the subject of the next column, tomorrow.
