Cooking with vegetable oils releases toxic cancer-causing chemicals, say experts.

What if you don't cook with oil at all? Is that bad?
I was also under the impression the low boiling point for olive oil made it more prone to undergo chemical transformation - which is bad.

I prefer coconut oil anyway, so this news doesn't really bother me.
cancer is different life that causes death.
no it would probably do the opposite.

Food science is ultimately going to end up recommending that we only consume water and that protein gruel from The Matrix.

They have but for other reason than cancer.

I'm not roasting my beef. I'm usually stir frying it. Nothing burnt. So does that mean it isn't carcinogenic? "High heat" is meaningless to me. A candle won't cook my steak but it can burn my finger. That's high heat to me. I need actual concrete numbers for this shit.

Eating grains is unavoidable for most of the world, and likely for most of the US. We wouldn't be able to support this large a population without them.
Also I've seen very little (if any) evidence that rice is harmful. You may be able to build a case around wheat or corn. And especially wheat that isn't whole wheat.
edit: Isn't lard full of trans fats?

Is Lard the same thing as margirine? I don't think we have Lard in Scandinavia!
This just in: high heat applied to long organic chains can cause chemical reactions that could lead to the creation of carcinogens. Oh noz.
Wonder where peanut oil falls on this, that's what I use as my high temp frying oil. Although for all I know they left it off because they're going to ban it from the world because allergies.

Your definition of cancer is too broad, when it appears that you're mainly referring to colorectal and breast cancers. Melanoma (a cancer treated by general surgeons) and head&neck cancers are absolutely attributed to lifestyle habits.
Don't worry about concrete numbers. Enjoy your beef however you want. Just get your colonoscopy at age 50 and pray to your deity of choice that you don't have cancer. Doesn't get simpler than that.

Healthy shmelthy. All I care about is that it tastes good and it doesn't seem to cause cancer. Yeeehhh!

Hydrogenized forms. You can get fresh lard, which is not.
It you see lard on a shelf, it's hydrogenized like Crisco.

Is there anything that doesn't cause cancer?

It's not news. I mean, this study might be new, but highly processed vegetable oils being bad has been known for a long time.
Olive oil, coconut oil and butter being the best choices has always been the recommendation to those who has been keeping up.
For example, this article is from 2 years ago, and it's definitely not the first one that talked about why we shouldn't use these unnatural oils:
http://authoritynutrition.com/6-reasons-why-vegetable-oils-are-toxic/
It's good that yet another scientific research backs this up though.
I see a lot of posts like this, and yes? These vegetable oils are a relatively new invention and they were highly processed in factories with added chemicals. It's not a reach to say highly processed food is usually bad for human beings.

I just use butter. It's delicious as hell and works.
Food science is too crazy though. I just want to stick to a diet with as little processing done to the food as possible. Give me some meat, brown rice, veggies and fruit and im good to go.

Hydrogenated or partially hydrogenated lard (stuff you'll often find in a supermarket, such as the Armor brand) do contain some trans fat, but not if it's rendered more traditionally.
Trans fats naturally (uh oh) occur in many animals, such as cows and deer. We get small amounts when we eat beef or butter, for example. It's not easy to find a lot of good research, but it's likely that this trans fat is not the same as what occurs during the hydrogenation process of vegetable oils.

No, they are not nearly the same thing.
Margarine is created from vegetable oils. Lard is rendered pig fat.
Surely you have farmers who keep pigs in Scandinavia?
Here on the west coast of the U.S., I've never found decent lard in a supermarket, so I buy it farmer's markets.

This is nothing new and has been known for decades, if not an entire century. Oils that contain unsaturation are inherently less oxidatively stable. When the double bond oxidizes, it creates peroxides, when the peroxides oxidize further, it creates anisidine like compounds such as aldehydes and ketones. Aldehyde and ketone containing compounds, particularly low molecular weight compounds, have been shown to be carcinogenic.
Olive oil is not exactly the best oil in terms of stability, a high oleic sunflower oil, high erucic rape (canola oil), palm oil, animal fat, or interesterified fat (crisco/margarine) are much more stable.
The amount of "processing" does not contribute to this in any meaningful way as long as the crude oil was of good quality to begin with... Actually, processed oils are much more stable as they remove pro-oxidants such as phosphatides, color bodies, and other minor components. Anti-oxidants also become pro-oxidants in large enough quantities, typically above 2500 ppm or so (using alpha-tocopherol) for example.
I would like to know what added chemicals are present in processed oils. Oil processing is more about removing unwanted components then adding things... In a process such as margarine production, it is just modifying the distribution of FA's among triglyceride species, but not "adding chemicals"

Congratulations. You post completely contradicts every scientific researches done in recent years.
The worst thing about food science is misinformation, and this is it.

Don't think I've seen fresh lard at any store then. All Crisco.
For what it is worth, I use olive oil most often. Probably followed by coconut oil. I use vegetable oil if the recipe calls for it. And I'm sure a lot of my snacks use vegetable oils. But I'd wither away to nothing if I gave up junk food. I'm underweight enough as it is.

How deeply do we want to think about this? Short 3 minute stir fry probably doesn't count as "high heat" except for the carmelized extreme outer coating. But that's an awful lot of surface area. Arguably by that metric, a few ounces of carmelized, browned beef might be more carcenogenic than an entire pan seared Porterhouse covered in carmelized onions and soaked in a beer mushroom sauce for an hour before being broiled in that same sauce.
Ceasar Salad on the side, and a baked potato, washed clean and rolled in sea salt and olive oil.

It's usually at your butcher section. It's not really in vogue these days. Used to be. Ethnic grocers also have the fresh version. The fresh version is usually refrigerated since non hydrogenated animal fats can go rancid quickly at room temperature.
You can also render your own lard from fat back.

Nothing really surprising here. Olive oil, coconut oil, and butter have been the nutritionally preferred cooking oils for a decade anyway.

Yup. My first response to this thread was "we've known this for a while, no?". After doing a fair bit of reading a number of years back I swapped to coconut oil for 90% of my cooking and olive oil for the remainder where the flavour of coconut oil can be overpowering.
