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:

1. 8 weeks is to short to see deep deleterious effects.
2. 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."
