Default Omega-6/Omega-3 Fatty Acids Ratio and Risk of Alzheimer's Disease

Vitasearch - search result

Summary: In a systematic review of studies which included the results from 14 human studies (7 prospective, 3 cross-sectional, 1 controlled, 3 case-control) and 13 animal studies, found that dietary omega-6 to omega-3 fatty acid ratio was found to affect brain composition, Alzheimer's disease pathology, and behavior (as according to animal studies), and revealed an association between the omega-6 to omega-3 ratio, cognitive decline, and incidence of dementia. The authors conclude, "This review supports growing evidence of a positive association between the dietary omega-6/omega-3 ratio and the risk of Alzheimer's disease."

I think they missed the point AGAIN. Omega 6 PUFAs are harmful and pro-inflammatory. Anything over minimal amounts is harmful. This is more so if they are oxidized/rancid as are ALL of the commercial seed oils on the grocery store shelf. Of course, they're worse still if they're "partially hydrogenated" which means they bring trans-fats along - this is the case for thousands of packaged snack foods.

Omega 3's which are barely needed at all for human health somewhat mitigate the harmful effects of Omega 6s. This "ratio" is nonsense. They take the HUGE consumption of Omega 6 PUFAs - which has come about only in the last few decades - as a "given" because they think it is so necessary to "protect" us from the evils of saturated fats until they can't see past their own noses.

What they need to be looking at is the relationship between heavy Omega 6 PUFA consumption and Alzheimer's - not to mention metabolic syndrome, obesity and diabetes. Duh! When there is a drastic change in the system (diabetes epidemic), look to the most RECENT changes as possible causes FIRST. There was no decrease in Omega 3 consumption concurrent with our current epidemic, but there was a HUGE increase in Omega 6 consumption.

(I think the key is the ratio, omega-6 is part of nature as well as omega-3 you can't avoid it and is needed for a healthy metabolism. There is just too much in modern diet because of seed oils and feeding animals grains.)

Omega-6 fatty acids are considered essential fatty acids: They are necessary for human health but the body can' t make them -- you have to get them through food. Along with omega-3 fatty acids, omega-6 fatty acids play a crucial role in brain function, as well as normal growth and development. Also known as polyunsaturated fatty acids (PUFAs), they help stimulate skin and hair growth, maintain bone health, regulate metabolism, and maintain the reproductive system.

Omega-6 fatty acids

Omega-6 and omega-3 PUFA are important structural components of cell membranes. When incorporated into phospholipids, they affect cell membrane properties such as fluidity, flexibility, permeability and the activity of membrane bound enzymes (12). DHA is selectively incorporated into retinal cell membranes and postsynaptic neuronal cell membranes, suggesting it plays important roles in vision and nervous system function.

There is a large study from India which very much points in the opposite direction. Yes, Omega 6s are [possibly] essential nutrients, although as I understand it, that long accepted axiom has recently come into question. In any case, they are required, or at least tolerated, in very small quantities. Nearly all sources of good saturated fat (e.g., beef tallow) contain plenty of PUFA to satisfy human needs. Swapping these real fats for PUFA-loaded seed oils raises the amount of Omega 6s to unprecedented levels.

Anyway, in the Indian study, the studied population shifted massively from their traditional (mostly saturated) fats like ghee and coconut oil to Wesson and Mazola, etc. Rates of all diseases of civilization skyrocketed. In the trial, a large number switched back to their traditional fats. There was a large drop in Omega 6 consumption, but NO change in the so-called "ratio". In fact, I think it changed slightly in the "wrong" direction.

The results were astounding and appeared to be a complete reversal of the previous increase in disease. With so much obsession on this "ratio", no one bothers to simply look at the correlation between excessive PUFA consumption and poor health. Basically, their desperately trying to rehabilitate their precious "healthy vegetable oils", evidence be damned. If they would bother, I think it would be very, very clear. Swapping out good saturated fats for PUFA seed oils is possibly just as bad as swapping out other foods for carbs. Both have happened massively concurrently with our current diabetes (etc.) epidemic.

The most recent and blatant changes need to be the first suspects!
