No, that obviously doesn't follow. Current scientific thinking is that ultra-processed, ultra-palatable food high in both sugar and fat is likely responsible for the obesity epidemic. Of course, the fat in those foods is, most of the time, vegetable oils (because they're cheap & most of them are healthier than their animal counterparts). However, it absolutely doesn't follow that vegetable oil in particular is the driver here. If one switched all of the vegetable oil in ultra-processed, ultra-palatable food with animal fats the result will very likely be exactly the same, except for an increase in CVD due to the increased saturated fat content.
