Coconut Oil Part 1: Improved Brain Function


Dr. Mary Newport came up with a theory a few years ago after wanting to help her husband who was suffering from Alzheimer's Disease. Her research lead her to believe that Alzhiemers is much like Diabetes of the Brain and that there is a problem with Glucose utilization in the brain. Further investigation lead her to believe that ketone bodies could be an alternative fuel for your brain that when digesting coconut oil (other fats as well), might offer profound benefits in the fight against Alzheimer's disease.

Now, Dr. Newport's research is being used to launch one of the first clinical trials of its kind to test her theory. The research is being done at the USF Health Byrd Alzheimer’s Institute.

Sixty-five patients diagnosed with mild to moderate Alzheimer’s have been enrolled to evaluate the effects of coconut oil on the disease, compared to a placebo. Dr. Newport hopes to have the results within a year.

This issue strikes close to home for Dr. Newport, whose husband has been battling the disease for years. As reported by CTV News:

“While there is currently no clinical data showing the benefits of coconut oil on the prevention and treatment of dementia, Newport -- whose husband Steve was diagnosed with Alzheimer’s at age 51 -- said she began to see improvements after starting him on four teaspoons of coconut oil per day.

‘Before the coconut oil, he could not tie his shoes. His weird slow gait… That improved. He walked normally and he was able to start running again.

He was able to start reading again, his conversation improved dramatically and then over several months we saw improvements in his memory,’ Newport said. Prior to starting him on coconut oil, Newport said none of the existing medications were working.”
Coconut Oil Appears to Be an Ideal Brain Food

There are only two types of fuel your body can convert into energy: carbs/sugar, or fat. Again, ketones are what your body produces when it converts fat (as opposed to glucose) into energy. And a primary source of ketone bodies are the medium-chain triglycerides (MCT) found in coconut oil. In fact, coconut oil contains about 66 percent MCTs.

Medium-chain triglycerides (MCT) are fats that are not processed by your body in the same manner as long-chain triglycerides. Normally, a fat taken into your body must be mixed with bile released from your gallbladder before it can be broken down in your digestive system.

But medium-chain triglycerides go directly to your liver, which naturally converts the oil into ketones, bypassing the bile entirely. Your liver then immediately releases the ketones into your bloodstream where they are transported to your brain to be readily used as fuel.

While your brain is quite happy running on glucose, there’s evidence suggesting that ketone bodies may actually help restore and renew neurons and nerve function in your brain, even after damage has set in. Interestingly, the mechanism of this MCT-ketone metabolism appears to be that your body treats MCTs as a carbohydrate and not a fat. This allows the ketone energy to hit your bloodstream without the normal insulin spike associated with carbohydrates entering your bloodstream. So in effect, coconut oil is a fat that acts like a carbohydrate when it comes to brain fuel.

How Much Coconut Oil Might You Need?

Therapeutic levels of MCTs have been studied at 20 grams per day. According to Dr. Newport's calculations, just over two tablespoons of coconut oil (about 35 ml or seven level teaspoons) would supply you with the equivalent of 20 grams of MCT, which is indicated as either a preventative measure against degenerative neurological diseases, or as a treatment for an already established case.

While more research certainly needs to be done in this area as well, I see no reason not to incorporate coconut oil in your diet, or the diet of a loved one who is exhibiting symptoms of brain degeneration. Coconut oil has so many profound health benefits; it’s not going to do any harm.

It’s worth noting that people tolerate coconut oil differently, and you may have to start slowly and build up to these therapeutic levels. My recommendation is to start with one teaspoon, taken with food in the mornings. Gradually add more coconut oil every few days until you are able to tolerate about four tablespoons. It’s best to take it with food, to avoid upsetting your stomach.
Low-Fat Craze Has Likely Contributed to Dramatic Rise in Alzheimer’s

A number of seriously flawed nutritional guidelines have contributed to more than a few health problems in the US, and the low-fat craze (aimed at preventing heart disease) is toward the top of that list. Not only does avoiding healthful fat promote heart disease, it also promotes brain diseases like Alzheimer’s.

According to neurologist Dr. David Perlmutter, fat avoidance and carbohydrate overconsumption are at the heart of the Alzheimer’s epidemic—which is an entirely preventable disease, driven by lifestyle factors such as diet. Dr. Perlmutter’s book, Grain Brain, provides a powerful argument for eliminating grains from your diet to protect your brain health. Another major factor is the development and increased consumption of genetically engineered grains, which are now pervasive in most processed foods sold in the US. Unfortunately, despite dire need, there’s little money available for research into treatments using regular food items. As Amanda Smith, Medical Director at University of South Florida (USF) Health Byrd Alzheimer's Institute told CTV News:

“The pharmaceutical industry is in this -- of course to make money for their companies, and of course they want to help people theoretically -- but at the end of the day it is about dollars and cents, and so money gets invested in things that are new or patent-able rather than things that are sitting on the shelf already.”
