Taking account that this is unproven in humans -- it's enough for me to avoid soybean oil, as cooking oil choice is not very important for my palate. That said, which oils would you use for frying and baking? Most high smoke point oils are, like soybean, polyunsaturated, so I'd guess that they could have some of the same (proposed) negative effects. Bonus points if the alternative is widely available (I see potential…

For frying and baking the so-called "high oleic" sunflower oil should be very good, if not the best.

It degrades less with heating than other oils and it has a very healthy fatty acid profile.

For salads or other food that is not cooked after adding oil, extra virgin olive oil may be preferred, because it contains other desirable substances besides fatty acids, but heating will degrade those, so for frying and baking olive oil does not have any advantage over the much cheaper high oleic sunflower oil.

Besides high oleic sunflower oil, there are also other kinds of oil that are claimed to be "high oleic", which should have similar frying properties, but I do not have any experience with those.

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 help fight free radicals in your body, which may reduce your risk of developing chronic diseases. Sesame oil has a balanced ratio of omega-3, omega-6, and omega-9 fatty acids.[..]

And I am from the south of india which is very hot. In the northern climes where it gets colder, sesame seed oil is substituted with mustard seed oil.

I don’t use olive oil for anything that requires heat. Mostly for salad dressings or drizzling etc. good olive oil..esp unrefined olive oil has very low smoke point. It’s actually harmful to use it for frying etc.

Regionally where olive oil is more abundant, grape seed oil is used for high smoke point cooking. I am also fond of avacado oil these day. I still stick to the trinity of coconut/sesame/ghee…but I also need to test other oils for diff gigs.

> Indian ghee We have been using ghee in India for thousands of years. If immigrant Indians are having problems, they should look into what changed in their diet and lifestyle after they immigrated.

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.

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.

From the study: > One additional note on this study — the research team has not yet isolated which chemicals in the oil are responsible for the changes they found in the hypothalamus. But they have ruled out two candidates. It is not linoleic acid, since the modified oil also produced genetic disruptions; nor is it stigmasterol, a cholesterol-like chemical found naturally in soybean oil. 1. We're not mammals that exp…

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

Look, if we're going to make major life changes on the basis of this one study, you've missed the opportunity for an all-chocolate diet.

Avocado oil is fantastic for high-temperature cooking (smoke point ~500F). "Pure" or "refined" olive oil has a smoke point of around 410F; it's EVOO that has the lower smoke point. Deep frying happens at ~375F. Coconut and MCT oils are great for baking, but they do have lower smoke points (320-350F) so they're inappropriate for frying.

I generally prefer cooking, frying, and baking with avocado oil, both because of its health profile and because because it's extremely flavor-neutral, while olive and coconut both add a distinct taste to the dish which may not necessarily be desirable.

What is soybean oil traditionally called in the US? I've never actually seen "soybean oil" myself (though it surely exists). Is this the same as "vegetable oil"?

Is it used in the UK much? I mostly see rapeseed, sunflower and olive oil used.

No, I don't believe I've ever seen it here, even though I frequent asian grocery stores.

Result of designing the food supply chain for manufacturer convenience and profit, instead of health of the people. Yeah, but it's the "free market" so we're all supposed to cheer at new products and boo at regulations.

It's the government that wrote the current food pyramid and teaches it to people in schools.

> The same UC Riverside research team found in 2015 that soybean oil induces obesity, diabetes, insulin resistance, and fatty liver in mice.

For obesity, 2 is wrong, and the study does explicitly mention "the SO + CO diet caused more weight gain over the 16-week study than the other HFD"

Plenish just has less LA, not zero, and they were trying to rule it out from a few genetic expressions they were looking at, not obesity.

"You'll feel the difference."

What difference will I feel that couldn't be explained simply by my expectation that I would feel different?

we have decided to go with having mustard seeds pressed for oil while being physically present for the process. the result is a much much better oil than the one that comes packaged. they say its "plain unprocessed oil" but there is a significant difference between what we get in our press and what comes in a bottle.
