This is a straw man. If you would like to defend seed oils please provide the response.Processing is another red herring, what is important is the end product.
Here is the typical process for drinking water....

My point is that seed oils cannot be considered bad just because they may have non-culinary uses or because they may have been processed. The problem with them is probably the Omega 6 fatty acid they contain and the sheer quantity of seed oil that is consumed, much of it being hidden in pre-prepared food. Dismissing all seed and vegetable oils as some sort of poison, is a gross simplification, we need to consider which oils, their constituents and what is a safe quantity to consume. All fats and oils vegetable or animal derived contain a mixture of fatty acids, only the ratios vary.This is a straw man. If you would like to defend seed oils please provide the response.

I would say that small quantities of any of them are probably ok. Omega 6 and Omega 3 are essential fatty acids, we need them and can't make them, does it make any difference if we get them from oils or animal fat as long as the quantities and ratio are reasonable. Butter is often held up as ideal but its Omega 6 to Omega 3 ratio is not as good as that of rapeseed oil for example.Well we know that zero are required so which would you profess are not poison and in what quantities?
There are mechanistic evidences about how the seed oils cause oxidation in the body, but the effort for me to find the references is disproportionate to the point.My point is that seed oils cannot be considered bad just because they may have non-culinary uses or because they may have been processed.

I saw a twitter feed with the usual suspects, the expected hashtags, the usual celebrities being referenced. It was a feast of the converted preaching to the converted. I see no new links to active or properly documented studies, or trials/ Much of what was on offer was blog material or conjecture, and nothing that would be useful to Dr Unwin who is seeking a scientific response to use as evidence in his efforts to progress this message forward. I am one of the converted myself, but it is easy to fall into the trap of unconscious bias simply from reading just one side of the debate.Dr David Unwin posed a question about references in relation to use of seed oils in Twitter today. Plenty of useful information in the replies.

Correct, association does not prove causality....The interesting way that the rise of diabetes, obesity and other chronic illness seems to track the sales of seed oils is well documented, but the evidence so far shows a possible relationship, but does not prove cause.
I gather the rise also tracks the consumption of wheat intake and sugar intake, too...The interesting way that the rise of diabetes, obesity and other chronic illness seems to track the sales of seed oils is well documented, but the evidence so far shows a possible relationship, but does not prove cause.
I agree on wheat and grains, but not sugar. The rise of sugar started earlier (1700's) so it rises, but not tracks with any sense of closeness. I remember as a kid that most of the UK sugar was extracted from Sugar Beet which was cultivated for that purpose, and the cane sugar (molasses) was mainly used for the liquor trade and expensive coffee and demarerra sugar and came mainly as cubes not spoons. I was also bought up in the time of sugar rationing which also curbed intake for a while. The rise in T2 diabetes seems to have jumped rapidly since the 1960's but T1D sees a more steady rise throughout. As I pointed out in the post earlier those interactive FAO graphics do show wheat rising rapidly over this time period since the 60's.I gather the rise also tracks the consumption of wheat intake and sugar intake, too...
What, no water!?I also don’t consume tap water.
Thank you for all that info and correcting my mis-remembering.I agree on wheat and grains, but not sugar.
I presume William and not FrederickIt also shows pre-Banting use of low carb as a treament.
Can't have people learning the truth!The WHO/ FAO used to have a massive database of world statistics where you could find info on enviroment, climate, consumption, population trade and commerce etc. I can no longer gain access to that info on the web, and web searches come up blank.
I sometimes consume them incidentally if I eat out because they are universally used in catering but I'd rather not and would love it if those places reverted to lard/tallow for frying.My point is that seed oils cannot be considered bad just because they may have non-culinary uses or because they may have been processed.

Surprised to see you quoting a mouse study..I am not sure of this source, but it talks about something I have seen in other studies.

Sorry, my post is technically off topic. Neither coconut nor soybean oils are Seed Oils, They are both plant derived oils classed as Major Oils. Coconut oil is a medium chain saturated fat *and the basis of MCT) , and soybean is a poly unsaturated oil or polyol as found in margarine. fake butter spreads and shortenings.The study says:
...All four diets contained the same number of calories and there was no significant difference in the amount of food eaten by the mice on the diets. Thus, the researchers were able to study the effects of the different oils and fructose in the context of a constant caloric intake.
Compared to mice on the high coconut oil diet, mice on the high soybean oil diet showed increased weight gain, larger fat deposits, a fatty liver with signs of injury, diabetes and insulin resistance, all of which are part of the Metabolic Syndrome. Fructose in the diet had less severe metabolic effects than soybean oil although it did cause more negative effects in the kidney and a marked increase in prolapsed rectums, a symptom of inflammatory bowel disease (IBD), which like obesity is on the rise.
