Canola oil linked to worsened memory and learning ability in Alzheimer's in mice

Is it just me or does 2 tablespoons of canola oil a day seem like a crazy amount for a mouse to consume? Mice usually eat around 5g of food per day, yet 2Tbsp of canola oil is 27g. Worse yet, the control had a normal diet instead of an alternative oil, so for all we know these results would occur with any mouse given large amounts of any vegetable oil. They mention a previous study with olive oil giving beneficial results, but for that study they simply used olive oil enriched mouse feed.

That lines up with what Brian Peskin's research on Essential Fatty Acids (EFAs) have shown; Oils high in Omega-3 and Omega-6 EFAs are generally oxidized during processing (which usually involves high heat), resulting in free-radical inducing oil.

It appears only cold pressed vegetable/seed oils are safe for human consumption.

Oils high in Omega-9 (Olive oil) or Saturated fats like Coconut and Animal fats do not suffer from this issue, as they are more resilient to heat and oxidation.

Fish oil supplements are also almost always rancid/oxidized, making them a common source of free-radicals.

A helpful clarification.

I was prescribed fish oil (EPA omega-3) for ADHD. 3g/day.

It seems like the dietary ratio of omega-3:6:9 is the most important.

IIRC, canola is often used because it's cheap. Personally, I use small amounts of avocado oil or butter in high temp cooking and olive oil for refrigerated or room temperature foods.
