There are lots of linkages, but basically they're highly inflammatory. For whatever reason, the oils that are the most shelf-stable are the most inflammatory ones.
The most common "seed oils" are
sunflower
safflower
canola
soybean
corn
peanut
It seems like the typical extraction process (expeller pressing) and subsequent processing are probably for a good bit of the problem, so you don't need to worry about consuming the oil if it's still part of the whole food.
Similarly, if you can find a cold pressed version of the oil, it's probably not as bad.
