Can you post those studies? Pretty much all the studies I’ve seen show that unsaturated fats are what you want.

Conclusions: Reducing saturated fat and replacing it with carbohydrate will not lower CHD events or CVD mortality although it will reduce total mortality. Replacing saturated fat with PUFA, MUFA or high-quality carbohydrate will lower CHD events.

Most meta-analyses, except the Nurses Health Study and the Health Professionals Follow up Study combined, that have examined replacement of total saturated fat with total carbohydrate in cohort studies have found no effect on CHD events or deaths. Only when replacement of saturated fat with polyunsaturated or monounsaturated fat or high quality carbohydrate is examined is benefit shown.
There is some recent evidence that some unsaturated fats are unhealthy from another perspective, like soybean oil, but that isn’t all of them (e.g. olive oil is still healthy for you).

That’s the one. :)
To add to that there seems to be a link between vegetable oil and weight gain when calories are kept equal between two groups of rodents.
