Abstract
Non-pedigree rats were injected subcutaneously either overheated oil or the oil and one of unsaturated fatty acids (linoleic, linolenic, oleic acids), or overheated oil and fresh oil. The greatest number of tumors in earlier terms occurred in the group of rats not receiving fatty acids. In simultaneous injection of overheated sunflower oil and fatty acids (oleic and linolenic), as well as fresh oil, tumors would arise considerably more rarely. Whereas, in injection of overheated sunflower oil and linoleic acid tumors did not arise at all. The mechanism of an inhibitory action of fatty acids on tumor development is discussed.

hm... can you translate the idea? How is over-heating changing the makeup / composition before it is consumed?

There are 2 levels of fat alteration when heating:
- Oxidative level
- PAH
At high temperatures organic compounds are partially cracked to smaller unstable fragments (pyrolysis), mostly radicals, which recombine to give relatively stable PAHs (pyrosynthesis).
PAH = Polycyclic Aromatic Hydrocarbons.

the question then is which is the healthiest and how much should we be eating

@Corngold said in seed oils are healthy:
uh... I don't know what's real anymore
Unsaturated lipid avoidance or depletion was never my takeaway either. I settled on ratios but joked with myself that might just be easier for me. I was already eating a lot of butter. I am a fake peater and this is my story.

"Some nasty comments on this one so I set moderation to strict, sorry if some good comments get removed. Debate is welcome, name calling and insults are not."
lol, poor chap.
Avoidance or depletion may just be a cope until someone can describe a missing factor or decipher it from what Ray already described. I think it's there personally, I just don't know how to put it. Working on that.

Your guess as good as mine. The stated reason of "a bit" of vitamin E for "2 or 3 tablespoons" of seed oils is stupid to me. But that fits in other ways.

3 tablespoons of sunflower oil is 26grams of pufa at a sitting. Take the vitamin e and pray too

Well I don't cook with canola anymore. I still get some zog from purchased foods and meat but at least I know beyond reasonable doubt that it is the big culprit in metabolic dysfunction. The smell of hot canola or even olive oil makes me gag. -
@Gardner I think that PUFA is mitochondrially toxic to regular cells as well as cancer cells.

I can speculate that in the experiment above the pure linoleic acids got conjugated (CLA ). Indeed, CLA has anticancer properties.
The term conjugated linoleic acid (CLA) refers to a mixture of linoleic acid positional and geometric isomers, characterized by having conjugated double bonds, not separated by a methylene group as in linoleic acid.
Sources of CLA:
CLA is found in dairy products and meat, particularly from ruminants (like cows).An overview of the effect of linoleic and conjugated-linoleic acids on the growth of several human tumor cell lines
While linoleic acid exerted different effects, ranging from inhibitory to neutral, even promoting growth, conjugated linoleic acid inhibited growth in all lines tested and was particularly effective against the more malignant cells, with the exception of mammary tumor cells, in which behavior was the opposite, the more malignant cell line being less affected. -

Why do you think so ?

All unused PUFA will cause problems. max 5-7 g but only if you eat bone broth. Glycine is required. otherwise, it could be less. No need every day as well.
PUFA are carcinogenic, dietary glycine blocks their effect

=> The findings apply to all oils containing enough PUFA to give you a dose of 5g - 7g per serving. 10g - 15g of glycine would be sufficient to block common uptake of PUFA’s. Combined with vitamin E (500 mg), even lower dose of glycine may be sufficient.Glycine as prevention for cancer treatment

Glycine is one of the most potent inhibitors of VEGF (Vascular endothelial growth factor) and many of the current blockbuster drugs are VEGF inhibitors. However, I think the more fundamental reason for glycine's effects are its opposition to PUFA, serotonin, estrogen, endotoxin (called LPS in the study below) and their anti-metabolic effects. -
the empire strikes back. lots of pro pufa content all the sudden

I guess nothing...just eating normal foods, especially meat (with some tendons in it)

Yes but not optimal so. Need a little more. So combine.
Note that taking glycine from powder and food won't probably give the same result in assimilation. Both are well (if no allergy from residue in powder).
Haidut said once that taking 10 g from powder will give 20 % assimilation for glycine.
Target for 2 g glycine is fine.
