nutritional mistakes! frying rapeseed oiled

hypersonic

I used to fry with it, but I've recently learnt that heating an omega 3 rich oil is a bad idea.
Is frying with rapeseed oil really that bad? I've switch to clarified butter (lactose intolerant), which I hope is a better choice?

I use coconut oil.

As a novice to nutrition, I use olive oil to fry. Is this good or bad?

slighty off topic here.

I never knew clarified butter was lactose free until i read your post and googled it.

Thanks for that!!

There is a debate about whether heat damages Omega 3 in oils, so if you are depending on Rapeseed oil as your sole Omega 3 source you 'might' be wasting your time. However Rapeseed oil is an extremely good frying oil, it has a high burning temperature so won't smoke unless you go mad and it has a very light flavour which I like. The light flavour makes it excellent for infusing with things like garlic or herbs. Eat oily fish if you want Omega 3, imho.

Butter is high in saturated fats and is generally not recommended, taking the milk solids out (clarification) is only going to increase the percentage. I eat butter, I love butter, but I scrape it onto toast once a day max, I never use it in a sandwich.

Olive oil on the other hand has a very low burning point and will smoke like hell even at medium heat. Use cheap olive oil for starting onions when you make a sauce, but otherwise you'd be better using rapeseed oil and save the olive oil (better quality) for the salad.

A bizarre thing though is that butter burns at medium temperatures even worse than olive oil, but mix them and they don't burn at all (well until cooking high temps are reached, even metals burn eventually).

it's dead easy to do with normal butter in the microwave and you can substitute it for really butter in cookies
I'm not 100% about the microwave as it supposedly damages some vitamins but I think it's only the water soluble one, but I must look it up.

phew! I honestly thought I'd been poisoning myself by frying with rapeseed oil. it was the high smoking temperature that got me started with it, so as long as u don't burn the oil it'll be ok.
I've also found that clarified butter has a high smoking temp some where around 230c. but there's definitely a butter flavour left with good for some food but not for everything eg sauces, so it good to have some choices. I haven't forgotten about coconut oil but it's definitely something I will try.

Mr. CooL ICE

Nothing wrong with butter or saturated fats.

Myself, I use coconut oil, olive oil and butter for cooking. I avoid seed and vegetable oils and only use nut oils as a condiment.

siochain

coconut oil for frying

Olive oil, walnut oil for salads

Real butter for the veg
