Conola oil worsens memory and increases risk of Alzheimers




We’ve long been pitched canola’s health benefits. If something is advertised it must be true right.

After all, Whole Foods uses it in all their prepared foods and many vegetarian and vegan products proudly promote it as a feature ingredient.

But when
scientists, who had shown the brain benefits of olive oil in mice, decided to run the same studies with canola oil, they uncovered a darker truth: Canola oil worsens memory and promotes amyloid plaques, a hallmark Alzheimer’s symptom.


In the olive oil study, researchers gave mice with Alzheimer’s Disease a diet enriched with extra-virgin olive oil and found that compared to the control group, the mice experienced improvements in memory as well as a reduction in amyloid plaques and phosphorylated tau, which creates the neurofibrillary tangles that degenerate the brain in Alzheimer’s. Thats scientific talk for BAD STUFF.


They replicated the study with canola oil, one of the cheapest and most widely used oils in the world, to see what effects it might have on the brain.


The control group ate a normal diet while the study group was fed the equivalent of two tablespoons a day of canola oil.

After 12 months, researchers observed the following in the canola oil mice:

  • They weighed significantly more than the control group.


  • They suffered impairments in working memory.

  • They had greatly reduced levels of a beneficial form of amyloid beta (amyloid beta 1-40). Amyloid beta 1-40 acts as a buffer to the damaging amyloid beta 1-42. When amyloid beta 1-40 goes down, it leaves the 1-42 form unchecked to degenerate the brain. i.e. NOT GOOD.

  • They showed reduced connectivity between neurons in the brain. Synapses are areas of neurons through which they communicate with one another, playing a vital role in memory formation and retrieval. The drop in amyloid beta 1-40 caused extensive synapse injury. Basically it caused the nerves to not talk to each other as well.

The scientists plan to conduct a follow-up study to determine how soon neuron damage begins to happen after regular consumption of canola oil, whether it impacts tau phosphorylation, and whether canola oil promotes other neurodegenerative diseases in addition to Alzheimer’s. Sounds like a good idea to me.


So what should you eat instead of canola oil?

When you eat out or buy processed and packaged foods, it’s difficult to find foods that don’t contain canola oil, soybean oil, or processed vegetable oils, none of which are healthy for the brain. It’s especially important to avoid hydrogenated or partially hydrogenated oils, which have also been linked with memory loss.

The brain is made up primarily of fat, approximately 60% fat, which means the fats you eat help determine the structure of your neurons and how well they are able to communicate with one another. For instance, hydrogenated fats have been shown to make cell membranes more rigid and less able to function properly.

Instead of industrially processed vegetable oils, use
extra virgin olive oil, avocado oil, coconut oil, and ghee. The less processed the better and be careful about heating any oils up too much when you are cooking.

Go feed your brain with some health fats.

Alzheimers & Type 3 Diabetes. The connection.







Why is Alzheimer’s being called type 3 diabetes

There is a TON of research being done on the link between how you eat, primarily in regards to the sugar and carbohydrates that you eat, and your risk of developing Alzheimer’s. Because of this link many researchers are now calling Alzheimer’s type 3 diabetes.
In fact, 80 of those with Alzheimers has insulin resistance or type 2 diabetesKind of scary and kind of cool at the same time. It looks as though this disease is turning out to be largely preventable. Not curable, but preventable.
Once there is brain damage associated with Alzheimer’s some of that damage can often be irreversible, depending on how much damage has been done.
Researches have found that the pancreas is not the only organ of the body that produces insulin. In fact, they found that the brain also produces its own insulin. Which when/if you think about it makes perfect sense. The brains main form of fuel is glucose. Not sugar but glucose. By the brain secreting its own insulin it can more likely ensure that it gets the energy it needs to function properly.
Mind blown right?!
They discovered that without the insulin your brain cells will die. duh - no gas, things stop running.
Insulin in the brain, and all cells for that matter enable the uptake of glucose into your cells. Think of glucose (not talking sugar or carbs) as the gas or fuel for your cells.
Studies are also finding that not only is insulting responsible for getting glucose into the cells of your brain, but it also helps with the regulation of certain neurotransmitters such as acetylcholine. Acetylcholine is the main transmitter responsible for memory and learning.

So here is the technical breakdown
If insulin levels are low or dysfunctional = poor brain energy = decreased acetylcholine = ???? What was I talking about?
So stop eating so many sugar foods and drinks, cut back on your grain and carbohydrate baed foods. These foods are triggering chronically high levels of glucose which is leading to the desensitization and blunting of the effects insulin should be having in your body and your brain. This is leading to what is now being called type 3 diabetes or Alzheimer’s.
There are many possible causes of glucose and insulin dysregulation. If you eat a fairly clean diet and are still having issues with controlling your glucose, or you are worried about developing Alzheimer’s.
