Seed Oils - as bad as sugar

Disagree. She flashes some research on the screen but does not list them in the notes. Her comments about trans fats are a red herring because they are no longer being produced. I had to stop using lauric acid, a 12-carbon saturated fat, because it caused me circulation problems. MCT oil, a mix of c8 & c10 saturated fats, seems to be ok for me in moderate amounts. I use flaxseed oil daily which has plenty of omega-3 fatty acids. All this is n=1 reporting. but the results of a large study shown below say that unsaturated fats are healthy, and they mostly come from seed oils.

Thanks for your insight. Are you saying that corn oil is good for us?

I have not researched these oils enough to advocate taking them as a health food, but have not seen any convincing evidence that they are bad, and I have done some looking. Another popular MD/health advocate was similarly negative about seed oils, but the researcher she cited ultimately backed off from negativity about seed oils.

They don't cause inflammation

First video – Nina Teicholz mostly did good work with her book “The Big Fat Surprise”. I really wish in the notes to this first video they referenced the studies that she cited, particularly any supporting her claim that vegetable oils caused cancer.

2nd video - thanks for this video. He does excellent work - actually goes through a vast amount of evidence - the list of references in his video notes is a mile long. For anyone who has not watched the video, based on extensive research he finds no evidence of adverse effects from seed oils.

3rd video - 3 journal refs. 2 of them are mouse studies. In the wild, the mouse diet is only 10 percent fat, so mouse studies of high-fat diets represent an abnormal condition for them. This does not necessarily apply to humans. Since there is no ethical prohibition on studying diets already in use by humans, there is no valid reason to be using mice for these studies instead. The remaining reference is a review citing the dangers of repeatedly heated vegetable oils such as in use by fast food restaurants. No argument there, although the creator of the 2nd video cites research to the contrary.

In my own research I found that high temperature cooking of protein, that is hot enough to cause browning, creates toxic chemicals that cause cardiovascular disease.

2nd video - "based on extensive research he finds no evidence of adverse effects from seed oils."

He explicitly limited his review. He only ask the question, "Are seed oils associated with inflammation?" There is a lot of research on the question, and the vast majority indicates that no, seed oils are not associated with increased inflammation.

But he did not investigate other potential adverse effects from seed oils.

Good point but also worth noting that inflammation measured included C-reactive protein which is a measure of cardiovascular inflammation

[ElliotGreen in reply to MBAnderson]

The second video, by Nutrition Made Simple!, is fantastic. I love the broad and deep dive into the scientific literature. He really presented it well. I am relieved that the peanut butter which is a staple in my diet probably does not increase inflammation.

It took a little digging but I found the study you reference.

Dehghan, Mahshid, et al. 2017. "Associations of fats and carbohydrate intake with cardiovascular disease and mortality in 18 countries from five continents (PURE): a prospective cohort study." The Lancet 390.10107: 2050-2062.

Apologies, I should have posted the link

I find hubby feels worse if going to cafe etc for meals too often instead of eating at home . I think it’s probably oils and additives.

[MBAnderson]

Good video. Controversial for sure. Bottom line; depends on your health.

I agree, for two reasons: one, the terrible omega 6 to 3 ratio in MOST (not all...flax oil is a great exception) and the other is the inherent instability of polyunsaturates and processing. A seed oil in itself isn't necessarily bad, but because of all their reactive double bonds they oxidize very quickly into trans fats, which--pretty much nobody disagrees anymore--are terrible.

poly=many

unsaturate=double bonds

A lot of them have begun to degrade (be made trans) before you even buy them, as they have to be processed like crazy in order to even exist. (How do you get oil out of corn?)

Think about flax oil--how it is usually sold in dark bottles and stored in the fridge in order to keep it fresh. You certainly wouldn't fry with it.

I don't treat seed oils like poison exactly--not like sugar. I'll eat salad dressing or mayonnaise in a restaurant once in a while, but I certainly don't keep any at home.
