“Even if you eat the most perfectly fresh pufa, by the time it reaches your stomach, it's deteriorating, and then when it gets into the tissue, it's farther along.

And some of it reaches your brain and is stored for years, but then every night your brain is renewing itself considerably. But unfortunately, during the night your free fatty acids in the blood coming out of your fat tissues rise and so the brain is trying to renew itself but what it finds in your bloodstream by the time you're 40 is polyunsaturated fatty acids that add to the damage of the brain.

So that every night when you're over the age of 40, your brain is at risk of deteriorating faster.”
