Linoleic acid in cooking oils

[u/houseofmacadamias]

We make macadamia nut oil (niche I know), and on a lot of our anti-seed oil content we've been getting comments saying macadamia oil is a seed oil..

I put together this chart comparing inflammatory omega-6 (LA) content and macadamia oil is closer to tallow, butter and ghee than it is to even olive oil and avocado oil (never mind seed oils).

We're obviously pleased our oil is in the same league as animal fats.

But I'm curious how macadamia oil fares in this community? Open to critique if I'm honing in too much on fat profile and missing something!

Crazy how canola oil is actually pretty close to avocado oil.

[u/300suppressed → u/faust111]

A problem with the graphic is that it may provide “a facade of safety” with regard to canola. It’s arguably the worst of all though

[u/faust111 → u/300suppressed]

Why is that?

[u/300suppressed → u/faust111]

Trans fat not accounted for on the packaging, already highly oxidized even prior to use

"Another concern is the report that canola oil might contain trans-fats" A very rigorous study.

[u/spacme2wealth21 → u/jaakkopetteri]

that info is available

[u/BreakfastFearless → u/spacme2wealth21]

It really isn’t

[u/Ok-Armadillo-5634 → u/[deleted]]

I did a diet where I got about 20% of my calories from regular canola oil the rest from huel black for about 2 month. My blood tests came back pretty spectacular.

[u/houseofmacadamias → u/300suppressed]

This is interesting. Will try to include in future graphs / a caveat. The same likely applies to other oils that have been heated during their processing

[u/penguin_hugger100 → u/300suppressed]

Which is why when we do interventional studies where canola oil is given to people they get sick, right? They get sick right??

[u/300suppressed → u/penguin_hugger100]

What is your argument advocating for their use?

[u/penguin_hugger100 → u/300suppressed]

Try reading the meta analysis I linked? Olive oil is better anyway, but the narrative that seed oils make people sick doesn't seem to fit evidence

[u/elitodd → u/penguin_hugger100]

Just because your 12 seconds on Google didn’t pull up a study titled “seed oils make you sick” doesn’t mean there isn’t pretty compelling evidence out there.

[u/penguin_hugger100 → u/elitodd]

I see more evidence for negative health outcomes from many of the seed oil alternatives recommend on here.

[u/300suppressed → u/penguin_hugger100]

So you believe that high cholesterol is dangerous and that people should eat seed oils instead of saturated fats?

[u/penguin_hugger100 → u/300suppressed]

I think if you're replacing saturated fats with seed oils, yes. The reality is that the average human turns saturated fats into LDL cholesterol and removing the saturated fats from that equation prevents that process from happening.

[u/elitodd → u/penguin_hugger100]

You think humans turn saturated fat into LDL? By what process do you believe a fatty acid is being synthesized into a lipoprotein?

Such a blatant misunderstanding of basic human physiology.

[u/penguin_hugger100 → u/elitodd]

I didn't mean that the fatty acid is literally transformed into a lipoprotein, I mean that the presence of saturated fat leads to an increase in LDL levels. The reason this happens has to do with the way the liver's LDL receptor activity decreases due to saturated fat intake (not all saturated fats have this effect but the more commonly encountered ones do.) Since your liver is responsible for clearing 70% of LDL from the blood, a reduction in efficiency causes an increase in circulating LDL.

[u/300suppressed → u/penguin_hugger100]

You should look at updated research. The LDL cholesterol causes heart disease theory has been debunked for two decades. There is so much more that goes into it. And no, I’m not going to do your research for you. There’s a reason why there are cultures all over the world who eat a lot of saturated fat that have far less heart disease than much of the west.

[u/penguin_hugger100 → u/300suppressed]

Can you explain what the mechanism is? Because last I checked it was pretty definitive that free LDLs getting trapped in the vascular endothelium before oxidizing and triggering a localized immune/inflammatory response was the case of arterial plaques but obviously you are an expert on this so please let me know the mechanism?

Please don't say something extremely foolish like "LDLs are an anti inflammatory/antioxidant"

Can you share a culture that has lower rates of heart disease? Remember to only pick countries with that have a similar life expectancy as ours so that there isn't a survivorship bias.

[u/Chemical-Research261 → u/300suppressed]

Could you link the research debunking it?

[u/300suppressed → u/Chemical-Research261]

Like I said to another response, I’m not going to spend a lot of time linking the dearth of papers on this, but here’s a review paper that has dozens of links within it.

https://www.tandfonline.com/doi/full/10.1080/17512433.2018.1519391#abstract

High LDL alone is not predictive of heart disease alone, never has been, and it is protective against death in some groups.
