Fat / Carbs and Alzheimers

Answered on August 19, 2014

Hi Everyone,

I am quite fascinated by the subject as I am trying to help my grandma make the leap from MCI to full blown dementia. We were especially amused by the Type 3 Diabetes nomenclature that now often comes up with Alzheimers, but the role of fat is still a bit of a puzzle.

Specifically, I am looking at two sources that literally state the opposite. What is everyone's take on this?

Source 1: http://commonhealth.wbur.org/2012/05/brain-on-butter

Same 'ol story, saturated fat is bad for you, bla bla bla. Comparing conventional butter and olive oil/using regular red meat, the typical nonsense. Even going so far as to say that trans fats have no impact on cognition. sigh.

Source 2: http://www.ncbi.nlm.nih.gov/pubmed/20932304

PubMed study on a group of Chinese seniors, stating that animal oil (i assume they mean sat fat) is correlated with MCI.

So my question is this:

The studies that DO accuse sat. fat of causing cognitive impairment, are they falling into the o6/o3 trap? Is it that excessive omega-6 balance that is causing the problem?

Or are these studies actually falling into another common science trap where they are seeing a correlation? Could it be that it is actually the carb intake of the control group that is causing the impact?

As per this study?

http://www.ncbi.nlm.nih.gov/pubmed/15082091

That suggests high carb diets may be related to cognitive damage?

Thoughts?

Just so you know, one of the things your second link was saying is this: "we found there were significant associations between the prevalence of mild cognitive impairment and low intake of animal oil and legume, in Chinese nonagenarians and centenarians".

Ya, that's a big leap to say that Saturated fat will cause mental decline and promote AD, from an observational study. Coconut oil which is pure saturated fat is beneficial for AD although it may be the ketones that produce the effect.

Obviously there isn't an answer yet (accept for a few dozen on here, perhaps). This is a variety on the main theme;

Could it be that it is actually the carb intake of the control group that is causing the impact?

My personal operating thesis is that a diet high in saturated fat and cholesterol is dangerous within the context of the SAD. In there are several things you could latch on to; the difference in O3:O6, the percent of calories as carbs, the percent of carbs as grain, the percent of carbs as simple sugars etc.

Either way, there are some facts out there. Regardless of diet, you might grow old, if you do you will look and feel old, some system will eventually fail and you'll die. In the course of all that, unfortunately, some people will lose their marbles, even if the eat ghee (except for a few dozen on here).
