To find the debate around seed oils confusing?

I try and eat well. Minimise UPFs etc. I’m not obsessive or anything but try to keep an eye on it.

But I don’t know what to believe when it comes to seed oils, especially rare seed and sunflower. Some people say it’s got too much omega 6 to omega 3 and so is very unhealthy and leads to inflammation. But others, including the manufacturers, claim many health benefits. Anyone got any basic language knowledge of this?

I also find it confusing and having listened to the recent Zoe podcast with Dr Sarah Berry and read what RespondLater's DH, I am still unsure.

I had been avoiding seed oils in my own cooking by using EVOO for salads etc and the mixed olive oil for cooking along either butter and goose fat (roasties). However OO is now sooo expensive I am using sunflower oil again.

In the podcast they said the cost of cold pressed is not reflected in the benefits. It's all so confusing.

Professor Sarah Berry has spent her entire career researching fats. She works at King's College London, as does Professor Tim Spector. They are obviously both making a good additional living out of ZOE. However, their academic credentials are impeccable. I'd listen to both of them before anybody on TikTok or YouTube.

@BunnyLake he said duck fat is ok in moderation, like most things.

He said there is a definite split amongst this scientific community on seed oils. In any trial depending on results it’s possible to steer down a certain route to look for the result you’re looking for. There is always error in data, there is correlation and causation. People keeping food diaries may or may not be very reliable and many trials don’t record how it’s been prepped.

His big issue is people cut out fat with the low fat movement and sugar started to dominate. He is anti corn syrup.

We never fry sausages and bacon, they are always baked @Gasp0deTheW0nderD0g when I make anything with minced meat and fry it off, I tend to buy the 5% or 10% fat content and never add oil to the pan, it’s already got plenty of fat.

Our own food intake is low in sweet things. Very much lots of veg meat, yogurt and cheese, some fruit.

Also, previous generations had far lower life expectancy. In my own extended family several men and one woman that I know of died of heart disease. Admittedly they were all smokers, which would have done a lot of damage, but their diet was poor by modern standards, and this was far enough back that statins weren't available and blood pressure wasn't well controlled.

Oh definitely, the trend has been a healthier population overall and food choices do make a definite difference, but it's not the whole story. As you say, your mum and dad ate a similar diet but with two different health outcomes.

Its not straightforward.

So I use olive oil for everything now (sometimes butter if that's nicer like for onions) but as we go into roast season I'm thinking olive oil taste might be a little too much, would goose fat be the best option for roast potatoes? I'm not worried about fat content perse I know it'll be bad in that regard, but trying to stick to real food.

Goose fat is gorgeous. Both on roast and fried potatoes. Also great as a rub for roast chicken, then all the additional seasoning you need is salt and pepper. Luckily it's easily available in Germany where I'm located, including, in November or so, raw for rendering at home. And good butchers carry their own gourmet versions with added grits or dried chanterelles as a spread - super yummy.

Oh dear god. Its no wonder we don't know whether we're coming or going.

I thought olive oil was supposed to be healthy in cooking. What is this "smoke point" you speak of?

FuckThePoPo · 03/10/2024 17:25

I use lard and drippIng, you only need a little bit. The mouthfeel and taste is lovely!

its all natural and cheap as well

Elphame · 03/10/2024 17:32

We use olive oil for everything.

I never deep fry.

I often wonder this. A huge amount of what I cook starts with frying a chopped onion and possibly garlic and other vegetables. Are they perhaps saying they don't eat fried eggs, bacon, sausages, steak etc and deep-fried foods?

I cook in the same way, but I don't think of it as frying as such - maybe people saying they "don't fry" are the same?

To me, fried onions are cooked in very hot fat and caramelise. The onions I start a stew with are in oil that seems to be less hot (I have never actually tested this) and go translucent rather than change colour.

It's convenient for the masses to eat them because they are cheap to produce and easy to store and transport. Goes a long way to solve a problem of a lot of people to provide "food" for.

But ask yourself who is this benefitting? Industry (someone's pockets) or my body?

I absolutely avoid them. If you'd like to learn more I'd suggest reading Dr Andrew Jenkinson's why we eat too much. It's also free as audio book on Spotify.

To what are you referring? All seed oils?

I used cold pressed hemp seed oil for everything... cooking and salads.

Hemp seed oil is very high in omega 6 which isn't great.

It has omega 3 also which is good but 3 x as much omega 6

I believe the smoke point is, well, the point at which oil, when heated, starts to smoke and therefore burn. I cook with EVOO all the time, including for shallow frying/sauteeing (I don’t deep fry stuff, the waste of oil seems not to make it worth it!) and I’ve rarely had a problem with it smoking. If it does I chuck a knob of butter in, which brings the smoke point down.

deeahgwitch · 04/10/2024 08:52

I don't like the taste of olive oil 😮

mikado1 · 06/02/2025 23:16

Once-used local seed oil ol, as I understand it. Reusing as people once did, a big no no.
Olive oil Inc EVOO fine up to 180 degrees tho does lose some but not all of its super benefits once cooked. Not suitable for wok cooking. October harvest the best if you can get some then.
I buy it in fill your own larder store and it is cloudy and really good.

It’s really difficult to find certain food that don’t have rapeseed oil.

The two that come to mind are mayonnaise and hummus. Even the ones that claim to contain olive oil still have rapeseed oil as an ingredient. Hunter Gatherer mayo and Waitrose hummus being the exception.

Yes I can and sometimes do make my own. Trying to avoid rapeseed oil, especially when eating out, is increasingly difficult.

Is the use of un heated rapeseed oil less harmful? I presume it’s not heated before being added to Houmus/mayo etc. Agreed though about how annoying it is that it’s added to things like Houmus, which would otherwise be a great healthy ‘on the go’ snack.

I'm a registered dietitian. Monounsaturated fats like olive oil and rapeseed oil can raise good cholesterol and lower bad cholesterol, they are the best fats for heart health. Polyunsaturated fats like sunflower oil can lower bad but also good cholesterol. Saturated fats like animal fats and coconut/palm oil raise bad cholesterol, they are worst for heart health. All fats are equally calorific and should only be consumed in small amounts to prevent unwanted weight gain.

This is specifically about seed oils and the issue of linoleic acid breaking down into pro-inflammatory compounds. As inflammation increases the risk of diabetes, depression, cardiovascular disease and cancer there is a debate about whether seed oils are bad for you or not. Not about their mono/poly affect on cholesterol and heart disease

BluebellsRinging · 09/02/2025 17:05

Ok, I’ve read the thread and I’m even more confused that I was before Confused. Think I’ll stick to olive oil for everything until something conclusive turns up.

What’s the deal with using extra virgin olive oil for cooking though? Isn’t that what all the Mediterraneans use?
