In the Netherlands it seems they claim about the opposite about oils and health. Most vegetable oils contain a lot of unsaturated fat. This type of fat is good for health compared with saturated fat .You've got the right idea. There's excess linoleic acid in seed oils. There's evidence that it can increase inflammation in the body.

They advise to limit the use fat/oil with saturated fat like butter, margarines, coconut and palm. Because these increase the cholesterol level in your body.
I have been looking for more info and its true that people often eat unbalanced and eat too much linoleic acids.
From an online newspaper:
People who consume a lot of linoleic acid have an increased risk of the chronic intestinal inflammation ulcerative colitis (UC). This is the conclusion of a sub-study by EPIC.
Linoleic acid is a polyunsaturated fatty acid, which is mainly found in red meat and vegetable oil and margarine. Because a very high consumption of polyunsaturated fatty acids may result in a higher risk of certain forms of cancer, the Dutch Health Council has previously set a maximum intake of these fats of 12 energy percent. That is approximately 33 grams per day for men and 27 grams for women.
From a site about health and vegetarian food
Saying omega 3 fatty oils are healthy/important (in balance):
Vegetable sources of omega 3 fatty acids (linolenic acid) are mainly linseed oil, rapeseed oil, walnuts (oil), soybean oil, linseed, chia seed and hemp seed. Some margarines also contain omega 3 fatty acids, but this is often due to the addition of fish oil.
From wikipedia about linoleic acids
It has long been thought that linoleic acid would be inflammatory, while linolenic acid would actually have an anti-inflammatory effect. These health claims in the field of ingredients in food still raise doubts in science.[ 1]
My own conclusion after reading all articles is that olive oil has the best of both worlds and is not overwhelming expensive. The first pressing is good to use in salads and cooking. But if you need a high temp (frying) its better to use the filtered olive oil (not refined). If you eat little fat in general its okay to use sunflower oil or another seed oil instead, that is good to use on high temps too.
Of course it’s better to avoid crusted fish and chips. Better eat plain fatty true sea-fish, boiled potatoes with a fresh salad or other vegetables.
