Trans fats are not that easy to spot for most people: they’re in meat, dairy, baked goods, fried foods. If you eat moderate amounts of the first two groups , and minimal of the second two, you’ll probably not consume many trans fats. The UK nutrition survey suggests that most people don’t consume more than 2% of calories (off the top of my head) from trans fats. Most margarines no longer contain trans fats.
The guidelines suggest unsaturated oil, of which olive oil is a type (specifically, mono unsaturated).
As for “Real foods, mostly plants, not too
much” - that would include whole grains and unprocessed carbs, would it not? Processed plant foods would fail the “ real foods” test, but things like beans, pulses, legumes and tofu wouldn’t.
The “go-to guru” was transparently Zoe Harcombe, in the OP’s case. Possibly other people as well, but the OP was quoting Ms Harcombe pretty much word for word at times. But lots of people settle on one or two experts as a source of information or advice - most people don’t have the time or the inclination to read loads of research for themselves. And most of us have a tendency to “hear what we want to hear, and disregard the rest”.
I think the government guidelines could be improved, but I don’t think they’re out of step with available evidence. I guess if you’ve posted on this thread you have at least some interest in the subject, but most people don’t really know what the guidelines say. And if interested people don’t really know, what about the rest of the population?
