Semantical bullshit. Can you not present any logical concepts?

Soybean oil is arguably not a food. It was never used as a food until
the soybean industry presented it as a food. Therefore, with soybean
oil not being a food, it becomes a fat substitute and/or an additive.

Soy beans have only been used as a food in east asia as a fermented
condiment, and only in very small amounts. At best it is a flavouring
agent. It is not a food. And "soy milk" is not milk, it is soy "juice"
and it has never been used as a food until (inadvisably) the very
latter part of the 20th century. And it isn't a juice because soy is
not a fruit.

The soyben is an historically inedible bean.

Soy oil is fine for industrial use but it is not food. Just look at the
industrial process needed to make it even closely ressemble a food.
Solvents and extractions and steam heat processes. Real food requires
much less industrial processing to make it real food. And the best
foods needs very little processing at all to make it into a meal.
