Depends on the individual, other dietary factors, exercise habits and lifestyle, liver health, etc. I can eat fairly high fat and I'm fine (for now) but the guy I work with so much as drives past a KFC and gets lipid issues. It's not a yes or no issue.
Moderation is a sensible approach. I probably eat too much fat overall but I rationalize it by chomping down on fats in forms I particularly enjoy, like sauces, cheeses, or desserts but not going too crazy with things where I won't really miss it, like just having jam on toast instead of both butter and jam or leaving out a yolk in scrambled eggs. In truth, this is motivated more by calorie count & vanity than by health concern.
I never eat hydrogenated fats like margarine. Pure poison that tastes like ass. I can't believe that shit is even still on the shelves. Btw pretty much any fat containing bakery product you buy, unless it's from a butter dedicated boutique bakery, will be made with hydrogenated fat. That's the unpleasant fatty film that you're aware of hanging around your mouth after eating.
