Fish oil kills neurons, Coconut oil dilutes this
-
The peroxidation of PUFA in the brain kills neurons, and the PUFAs stay in the brain for a very long time. Coconut oil can be used to dilute the PUFAs in the brain making it more saturated.

That study is pretty poorly run. It said 17% corn oil diet had no impact on brain polyunsaturated fat levels. 2.2% corn oil and 2.2% lard also had no effect. This did not mean the saturated fat protected the rats. It means it had no difference than the 17% corn oil rats.
Then they fed rats 17% corn oil diet PLUS 15% cod or 13% salmon oils. That’s basically DOUBLING their fat intake. That’s 30% of the diet in fats, 15% of which is fish oils. 15% of calories as fish oils is really ridiculous. Only when fed double the amount of PUFA did it cause brain omega 3 levels to rise and omega 6 levels to reduce. And adding vitamin e does not help prevent this.
Doesn’t really seem conclusive of much imo. It actually kind of tells us we can eat up to 17% PUFA and not change brain PUFA content lol.

Yes, indeed. Well seen.
Not realist.
And moreover:- 8 weeks is to short to see deep deleterious effects.
- When specifying "vitamin alpha-tocopherol" is not sufficient. I don't take into account studies with dl-toco (synthetic). Less efficient.
"the fatty acid composition of brain PUFA was significantly altered, even if alpha-tocopherol was added to the salmon-oil diet."

"Group 1 (10 rats) was fed a
diet containing 4.4% (w/w) fat consisting of a lard
(2.2%) and corn-oil (2.2%) mixture. Experimental
animals were fed a 17% lipid diet; group 2, which
served as control (10 rats), received a corn-oil diet
(17% w/w); group 3 (10 rats) was fed 2% corn oil
with 15% cod-liver oil; group 4 (12 rats) received a
salmon-oil-enriched diet (12.5% w/w) supple-
mented with 4.5% of corn oil."
