New research shows that people with a higher blood DHA level are 49% less likely to develop Alzheimer's disease vs. those with lower levels, according to the Fatty Acid Research Institute (FARI). The study, led by Aleix Sala-Vila, Ph.D., suggested that providing extra dietary omega-3 DHA, especially for those carrying the ApoE4 gene (which approximately doubles an individual's susceptibility to develop AD) might slow the development of the disease. Such a cost-effective, low-risk dietary intervention like this could potentially save billions in health care costs.
In this prospective observational study, researchers examined the association of red blood cell (RBC) docosahexaenoic acid (DHA) with incident Alzheimer's Disease (AD), while also testing for an interaction with APOE-ε4 carriership.
Risk for incident AD in the highest RBC DHA quintile (Q5, >6.1%) was 49% lower compared with the lowest quintile (Q1, <3.8%). An increase in RBC DHA from Q1 to Q5 was predicted to provide an estimated 4.7 additional years of life free of AD.
Further, the researchers noted that an increased intake of DHA might lower risk for developing AD, particularly in higher-risk individuals such as those carrying the APOE-ε4 allele, suggesting that they may benefit more from higher DHA levels than non-carriers.
So how does this paper stack up to others in this area?
"Most interestingly, 15 years ago similar findings were reported by Schaefer et al. in the parents of the individuals who were the focus of this present investigation (i.e., the Original Framingham Heart Study cohort). Schaefer et al. reported that participants in the top quartile of plasma phosphatidylcholine DHA experienced a significant, 47% reduction in the risk of developing all-cause dementia compared with those with lower levels," Dr. Harris continued. "Similar findings a generation apart in a similar genetic pool provide considerable confirmation of this DHA-dementia relationship."

This can’t be true. Every fish I ever caught was pretty dumb, and aptly called “a sucker”. J/K
I dispute the 15-20%. It’s closer to 5% and only that high in women (lower in men, an enzymatic thing).
Thus this list I found in a quick internet search is total bullshit:
Top 10 Foods Highest in Omega 3 Fatty Acids
1.Flax Seeds.
2. Chia Seeds.
3. Fish (Salmon)
4. Walnuts.
5. Firm Tofu.
6. Shellfish (Oysters)
7. Canola Oil.
8. Navy Beans.
9. Brussels Sprouts.
10. Avocados.

This list is appropriate (minus the non-fish items):
12 Foods That Are Very High in Omega-3
1. Mackerel ( 4,580 mg per serving)
2. Salmon ( 2,150 mg per serving)
3. Cod liver oil ( 2,438 mg per serving)
4. Herring ( 2,150 mg per serving)
5. Oysters (329 mg per serving)

I left the sardines & anchovies off the list because they’re typically canned, and the canning process destroys the fragile O-3. If you can find them fresh and tolerate them, go for it.
Fish must be cooked low & slow (think poached) to retain health benefit.
Otherwise all you’re eating is fish flavored chicken.
Cod liver oil must be fermented, otherwise the likelihood is that it’s been processed and had negligible O-3, if any at all.
Reminder: All supplements are unregulated. Most fish oil capsules are a total rip-off and likely unhealthy IMHO.
I prefer river trout because it’s low in mercury and not exposed to Fukushima contamination.
Bacon has Omega-3
For supplements, I use ConsumerLab and Consumer Report for their independent tests of the oil and its rancidity.
Strangely, the best for the price is Walmart Spring Valley 1,000 and 2,000 mg Omega-3 fish capsules. Just under 9 cents a capsule in the 180 count bottle.
Good. Of the other foods, I only really eat walnuts regularly. And pickled herring, mostly in winter, for some reason.
But bacon.....it’s a staple & we are just mere weeks away from BLT binging time.
I do hope that wasn’t some droll FR bacon trope.
Good reminder to load up on bacon.
Abstract
Pork is the most widely eaten meat in the world, but typical feeding practices give it a high omega-6 (n-6) to omega-3 (n-3) fatty acid ratio and make it a poor source of n-3 fatty acids.
Pork as a Source of Omega-3 (n-3) Fatty Acids
The problem is that no one really knows what FCLO is, or should be. The product promoted by the Weston Price Foundation was shown to be not cod-liver (it was pollock) and demonstrably putrid.
Supposedly, the Romans used FCLO, but there does not appear to be any agreement as to how this was made.
“Bacon has Omega-3”
Sounds good. Bacon cheeseburgers are the best.
You got your info from the government, I got mine from a Pro-Bacon site:)
Yeah, I remember the dust-up over FCLO and WAPF. (I’m a long-time member.) It was alleged that the head of the WAPF supported the fellow selling the putrid stuff because his surname was the same as her maiden name. I bought a small bottle of FCLO and had to discard it. Something was terribly wrong with it. The best source high-quality cod liver oil is simply canned cod livers.
I no longer trust CR for reasons I won't go into here.
The problem is that independent lab tests are far & few between, coupled with the fact that unless the samples were random, there's zero integrity AND products change.
Hence my favoring of fish (I just wish that I was in FL/East Coast rather than the polluted Pacific coast).
Therefore, may we conclude;
... people with a low omega-3 DHA level are at 51% higher risk.
Very convincing...WTF. Analytics comes to medicine.
Fish Oil pills are usually so big that I can’t swallow them. I don’t see why you can’t just snip them, squeeze the oil into something like tomato juice, and down it.
Kippered herring is very good, too, though it’s gone way up in price of late.
I use apple juice and or cranapple juice.
Thanks.
Brussel sprouts are a nice serving out of the Air Fryer. I piop them in frozen along with a hand full of frozen tater tots. 300 for 10 minutes. Use some Crystal hot sauce if desired. Good eats.
