To note, even eggs and lard have large amounts of Linoleic acid, and I'm pretty sure lard and eggs have existed in the human diet for as long as chickens and pigs as livestock have existed.

There are 3 characteristics of the oils that influence how healthy they are. The first is the fatty acid profile, i.e. the relative quantities of fatty acids. It is best when the most abundant fatty acid is oleic acid. This is true for olive oil and avocado oil and for certain varieties of other oils which are claimed to be "high oleic", e.g. high oleic sunflower oil. For the oils with high percentage of saturated fa…

As I understand it, the evidence for erucic acid being harmful has been called into question more recently. See the footnotes for https://en.wikipedia.org/wiki/Erucic_acid#Health_effects

Now it is understood that erucic acid is not so dangerous as initially believed, because rats are much more sensitive to it than most other mammals.

Nevertheless, the same paragraph from Wikipedia says that erucic acid was shown to also cause heart problems in pigs, but at much higher quantities than in rats. Therefore it is dangerous, but only when eaten in larger quantities.

Canola oil is widely used in food and it contains erucic acid. However it contains much less than traditional rapeseed oil, so the current food standards are based on the assumption that it should not have bad effects when eaten in normal quantities.

Nevertheless, someone cautious could avoid it entirely, because the only desirable property of the oils which contain erucic acid is that they are cheap.

Who ever told anyone to drink soybean oil?

On the other hand, I consume massive amounts of flaxseed oil (insane amounts of omega3), olive oil, sunflower seed oil every single day. I have no issues with weight, no heart or blood vessel issues, blockages.

Ingredient isolation studies of foods are a complete disservice to scientific method.

Any particular food can be part of a healthy diet and lifestyle, absolutely any.

People today are sedentary, just look at natives living in wilderness across the world. They gorge on honey, occasionally eat meat and have insanely strong skeletons and muscles. Look at others that eat only meat, milk and blood, have massive amounts of atherosclerotic plaque, but given their lifestyle in the wilderness, their blood vessels expand and are insanely flexible, only a few unlucky ones die of heart attack very young.

The RDA for Calcium in Western world is so high due to sedentary lifestyle not promoting usage of calcium by the body. There are healthy populations, consuming half the amount and have even less bone fractures.

Care explaining what bizarre mental issues?

I guess it would best be described as enhancement of repetitive, obsessive thoughts and just in general not feeling good and even angry for the rest of the day after eating them. It was a really weird time.

I have the same thing. It took me ten years to rule things out. Plain as day, if I have soy oil, I will go a little wayward emotionally, mentally, and if I have enough, also noticeable skin issues - canker sores, flaking skin, scalp pimples, and random itchy patches I'll scratch to bleeding. Oh, and if I have enough, in a short amount of time, I can easily trigger a migraine. Sushi with soy oil, mayonnaise (soybean oil), and fried foods are all drifting away from me.

I'm not allergic to soy - I went to an allergy doctor and did the little skin application test, and it's not a histamine reaction. So the term is "sensitive" - I'm "soy sensitive".

If I eat 'clean' for 14 to 21 days, I get a clarity that compels me to continue avoiding it. I'm happy to connect with anyone (profile) that wants to swap notes on this - it's incredibly frustrating to figure out. Dealing with it, not so much. Almost all aspects improve with its avoidance.

The three oils/fat I have been taught to use in my Indian kitchen are: sesame seed oil, ghee and coconut oil. Sesame seed oil because it has a high smoke point. Ditto with ghee. The choice of oils always has to do with smoke point and hence what we use it for in the kitchen. [..] Sesame oil is full of antioxidants. Along with vitamin E and phytosterols, it contains lignans, sesamol, and sesaminol. These compounds hel…

Wow. Read one article from the web and everything else is ‘BS’. I mentioned that this is for an Indian kitchen. Specifically. Our cooking involves tadka(tempering) and sautéing..we use more pulses/lentils and one pot vegetable preparations than meat..meat requires high heat for Maillard reactions. High smoke point is not to just guide for deep frying in Indian kitchens. We don’t use oil just for deep frying. Everythi…

To back up and... refine... your point. EVOO does contain non-oil elements that will burn when heated and that's obviously not something anyone wants. However, pure olive oil (the yellow stuff) has a higher smoke point and is suitable for frying. In Germany they actually sell refined olive oil specified as Bratolivenöl, "literally frying olive oil", and it will state on the label that it is safe to heat up to 210 C.

Indians in India have skyrocketing diabetes and obesity numbers in recent decades. 20+ years ago you would struggle to see a single non thin person. Drastic increase in quantity of ghee (and sugar since a lot of Indian tests are a lot of ghee and sugar) consumed and reduction in labor (trading strenuous, perspiring work for air conditioned, sitting work) could be relevant factors that make ghee consumption from the p…

> Indians in India have skyrocketing diabetes and obesity numbers in recent decades About a decade ago, my Indian colleagues told me that Indians had been encouraged to switch away from ghee, based on health concerns. I forget which oil most moved to, but I think it was palm, vegetable or sunflower oil. In addition, they said consumption of refined sugar had skyrocketed , where palm sugar had previously been used. Gh…

> Ghee has been consumed for centuries (at least) in India - I wonder if it's these ghee alternatives and refined sugar are the main causes of increased diabetes and obesity.

Yes, carbohydrates like sugar are of course a huge part of the problem, but the health crisis has many factors and my intention was to convey that ghee has downsides. Saturated fats are saturated fats regardless of how many thousand years they have been used.

Go try and eat only coconut oil for say, 2 weeks, you'll feel the difference.

"You'll feel the difference." What difference will I feel that couldn't be explained simply by my expectation that I would feel different?

You'll feel a difference because coconut has a high amount of MCT (medium chain triglycerides). MCT is often touted as a weightloss tool, I've seen plenty of posts talking about pigs not getting fat on MCT, or how it takes more calories to break it apart (which is bullshit) or it some how raises your body temp/metabolism.

The truth is that our stomach has a hard time digesting a sudden influx of MCT. Adding a large amount of MCT to a diet previously free of MCT will cause nausea. And that short term nausea is largely the cause of any "weightloss" seen by MCT. The studies that study MCT and show weightloss are all short term studies, and not the 6-12 month study you really need for weightloss.

In short, you'll feel a difference because coconut oil upsets your stomach. Not because it's a non-animal fat. Hell, we use sesame, peanut, canola, and olive oils all the time. Replace all your dietary fat with canola oil or olive oil and you'll not notice. Will probably have health benefits because of the reduction in saturated fats.

Economics, probably -- sunflowers and canola grow more easily. Olive oil is a nice pan-frying oil, it's what I use. Linguistic thing: When Americans talk about oil for frying, in my experience, they are a fair bit more likely than us to specifically mean deep frying, for which olive oil is no use. Way more of a deep-frying culture, from several different influences. American cooks are slightly more likely (than the B…

“Broiling” would refer to using the broiler on one’s oven, I’ve never heard that term used to describe pan-frying. Terms I have heard are sautéed and seared

As another aside, deep fat frying is quite uncommon in homes in the UK now.

Many people under the age of say 25 will never have eaten deep-fried food cooked at home.

There was quite a concerted campaign against it in the early 80s because so many house fires and serious injuries were caused by either unsafe fryers or unsafe technique. Safety campaigns, TV ads, fire brigade campaigns, a campaign to get people to fit extractor hoods and smoke detectors etc. Coincided with a public health campaign aimed at getting us to lower our fat intake, about deep fried food, full fat milk etc.; government "nudge unit" stuff.

Time was, deep fried food was a staple of cheap home cooking; nowadays a deep fat fryer is really an enthusiast cook's appliance, in white British homes at least.

avocado might not be so trustworthy, see: https://news.ycombinator.com/item?id=30105062 ghee is a great alternative IMO.

Has anyone done the research to find a reputable olive oil brand?

It's mentioned in the linked to article:

> Only two brands produced samples that were pure and nonoxidized. Those were Chosen Foods and Marianne’s Avocado Oil, both refined avocado oils made in Mexico. Among the virgin grades, CalPure produced in California was pure and fresher than the other samples in the same grade

> We have common genes going back to mammals who did experience torpor. We also have genes that are related to cows, have you tried subsisting on grass? Your argument is farcical and entirely based on the preaching of a snake oil salesman, in a comments section based on a torpid male mouse study that specifically refutes the argument you're making.

Um, don't we have something like 30% of our DNA in common with actual grass, nevermind grass eaters?
