They don't no and that's why I always say it boils back down to personal responsibility. Most people that are so anti seed oils don't eat super clean 100% of the time so I don't know why they get so over sensitive when I call this nonsense out. 

Reduce seed oils and food that contain them as much as you can, take a decent omega 3 supplement unless on medications that thin the blood. Do regularly blood tests to track inflammatory markers.
