i've been told olive oil "loses all its nutritional values if it's heated"
is this true?
>>35212926
Ask yourself "where would all that nutrition go?"
>>35212931
Vaporizes of course
>>35212931
i've been told word for word "all the anti cholesterol properties and nutritional values vanish"
i'm not asking for common sense, i'm asking for sources, studies, etc
Well vitamins are destroyed at certain temperatures... so heating it up would destroy some of the vitamins
>>35212943
You're literally using oil for cooking because it doesn't easily vaporate.
>>35212957
desu i use it for the taste
>>35212926
okay, first google result is
http://www.medicaldaily.com/extra-virgin-olive-oil-loses-health-benefits-when-heated-so-save-your-money-247237
according to that article, olive oil does lose nutritional value depending on the heat and time it is heated, i'm gonna check if it links any solid source
>>35212926
first source is this
http://www.sciencedirect.com/science/article/pii/S0963996913002421
unfortunately they sell access to it the fucking jews.
however they were kind enough to share the highlights for fre :
"Highlights
•
The use of virgin olive oil for thermal processing is ambiguous.
•
All olive oil grades performance was generally better than with common vegetable oils.
•
Most published studies were performed without the effect of food interaction.
•
Microwave heating effects remain questionable."
>>35212926
It is still better than cooking in lard or butter, maybe just use enough so it doesn't stick to your pan then add it on top after you've cooked.
>>35212926
Depends on what you define as the "nutritional value". In a more general sense, that is certainly not true. By far most of the nutritional value is preserved, however it's perfectly possible that some vitamins and whatnot can't handle the heat. Fortunately, there are hardly any of those in olive oil anyway. Olive oil has a high share of unsaturated fats, which is considered valuable (I think that's what is meant by "nutritional value" here). Unsaturated fats are generally not stable. High heat can damage them. However, the unsaturated fats in olive oil are mostly monounsaturated. Those are generally very stable.
So no, I don't think it's true. It's of course perfectly plausible that the polyunsaturated fats are lost (11%), but that's not "most" or even "all" of it's nutritional value.
So fuck that, you can cook with olive oil just fine. And unsaturated fats are not the grail of nutrition, it's recommendable to make sure that about a third of all fats you eat are unsaturated, but it's not really that relevant at all. It's blown up like every nutrition fad is.
>>35212963
okay i've read the article, all it says is shit like "don't heat it too much teehee :>" without giving a temperature or a cooking time.
i'm gonna review other results.
>>35212949
i will check the vitamin content of the olive oil
>>35212980
it's obviously better than lard/butter, and i mostly use it too cook eggs, which lasts for like 2-3 minutes.
adding on top after i've cooked is a great idea tho
>>35213006
thx for the input anon, did you study chemistry/nutrition?
>>35212926
second google result is
http://www.drgourmet.com/askdrgourmet/foods/oliveoilmyth.shtml#.Vmqmzr-W7rY
and the article quotes :
"A group whose report was published in the Journal of Agricultural Food Chemistry heated olive oil to 350°F for 36 hours. (2007 Nov 14;55(23):9646-54) There were some minor changes in the oil but they found very little oxidation and the smaller antioxidant chemicals were preserved intact."
i'll see if i can find the source on this
>>35212926
It's an old wives tale. It's one of the best oils to cook/fry with on the withstanding changes to heat front but it's very rich so is often a bit much on the taste front
>>35212926
>i've been told
how fat was the person who told you that?
Why cook in anything other than coconut oil?
Or refined coconut oil?
I mean, shortening / lard is good, but it's an animal product so has no place in an educated person's kitchen. 'cept maybe at christmas amirite?
Various oils are great but why cook with them? I'm using cooking as the process of changing the make up of food through the application of heat - putting together a salad (an applying delicsious oil) isn't what I'm talking about. In those cases, apply olive oil liberally.
>>35213175
Coconut oil is a p recent fad.
And obviously because different flavours and smoke points and fat profiles and so on.
>>35213134
not fat
>>35213175
i also use coconut oil and flax oil
>>35212926
Foodbro here. We did the calculations (basic chemistry) and short answer: no. You need to heat it up a lot more that you do for basic cooking and for a much longer time. Olive oil is the most heat stable and healty oil you can use for cooking, next to coconut oil but that shit too expensive
>>35213265
thanks foodbro
>>35213198
>flax oil
>Not spinning it into bowstrings for 1600% profit
>>35213265
got a massive tub of pure coconut oil at my local market for £2.00.. the same size tub same brand costs £7.00 at your average health food shop.. look around and youll find it for a decent price
correct op, olive oil is best injected raw
>>35213042
Just get a green pan no oil needed again
>>35212926
FUCKING AMERICANS ARE SO FUCKING STUPID
>>35212926
I know that for what concerns heating and maintaining its nutrients/not morphing in cancer grease, olive oil is definitely the best oil
I drink this stuff every morning. Slightly chilled. Why aren't you?
>>35213042
>woman top pic on right
she's hot. sauce?
>>35214006
not american.
Good quality olive oil has various time and heat/light sensitive compounds in it.
All the omegas (3, 6, and 9) are heat and light sensitive - over time, they will break down in oil, which is why you should only buy fresh olive oil. Always check for an expiry date. Cooking with omegas will always cause them to break down - the higher the temp the worse.
Olive oil also contains a variety of antioxidant compounds. You can taste these in good quality olive oil by the tannic flavour that is bitter and makes you cough. These are also heat sensitive and break down when fried. If your olive oil is smooth and flavourless, it's either watered down with cheaper oil, not really virgin or old.
Most olive oil you buy in the supermarket isn't good olive oil - especially ones imported from spain and italy. A lot are cut with other oils. Companies don't get checked and consumers don't know how to tell good from bad olive oil - and if you're just using it for cooking then it doesnt matter.
http://www.theguardian.com/lifeandstyle/2012/jan/04/olive-oil-real-thing
If you want to buy good olive oil, buy at farmers markets, and buy local. If you can buy a current press, better. Always try to get current olive oil. Freshly pressed olive oil should be cloudy.
tldr: most olive oil you buy in the shops isn't really worth consuming raw, so you may as well cook with it
>>35212926
this is why we need better funding for our public schools
>>35213265
What about rice oil? I've heard its best for cooking due to very high oxidation temperature
>>35212926
Olive oil is mostly unsaturated fat, and when you heat it it becomes saturated
Source: I literally did it in lab a few weeks ago
>>35212926
than why are people using olve oil you fag
>>35212926
if the oil you are cooking in is the make or break for your health/gains, then you have a serious problem
That's like eating a Smart Ones and thinking that really is health food.
>>35215567
How else are you supposed to cook food nigga
>>35215198
at what temperature, and for how long did you heat the oil? did 100% of the unsaturated fat turn into saturated fat?
>>35214594
thanks a lot for the input anon
>>35214861
never tried it, i'll look into it
>>35215567
the devil is in the details
my faggot ass vegan step brother doesn't eat olive oil at all and my saint of a mom has to cook everything twice for his candy ass. We're italian and there literally isn't a single dish in Mediterranean cuisine that doesn't incorporate olive oil in some way.
>he eats oreos like its his job
>all other fats are fair game in his mind
i h8 vegans
>>35213175
>animal products
>no place in the kitchen
You do you, anon, but I'm gonna keep eating animals.
Props on the soft troll, tho.

>titties.rar
>>35212931
u trolling breu?
Changes the structure of the fat.
Consume fats that are liquid at room temperature.
Coconut oil is the exception to that one. Monounsaturated and whatevs. it's got some other stuff going on.
>>35212926
but yeah avoid cooking with olive oil.
>>35212943
Then smoke it through a vaporizer
>ITT: Semen Demons

That one legged reverse squat was pathetic.
