Unless you are seriously actively avoiding it I would be highly skeptical your average person actually avoids seed oil in their everyday eating because it’s in almost everything packaged and used at almost all restaurants/take out places. And olive oil is an unsaturated fat. It has more monounsaturated fats than seed oils but still contains polyunsaturated fats. You’d really need to stick to only butter and tallow to really maintain a low Pufa diet, as well as avoid high Pufa foods like fish and fish oils. The idea is your stored fat should be primarily saturated fats that are stable when exposed to heat and oxygen.
