Once I saw the "how it's made" on seed oils, I was expecting "Press the seeds, filter out any chunks that made it through" and thought the machines were kinda cool.

Then it goes to "But that only extracts 70% of the oil." The process after seems more in line with what you would expect if extracting the gasoline from crude oil.

Sugar and flour are just simple and empty carbs at the end of the day. Zero nutritional value (though bread making can add some) but can be powerful if used by someone who knows how to use it.

Not detrimental in moderation.

Seed oils aren't as simple as cold pressed oils either, so I'm pretty sure you're correct.

Corn syrups (so, concentrated sugars from corn) are most likely the largest contributor to the world's obesity problem, as it is startling what people add high fructose corn syrup to.
