I had a friend who thought chocolate milk came from African women because he had never seen a cow before.
Organic just means they didn't use pesticides. Something can be processed and organic. You would never eat canola seeds because they would pass right through you, most seeds don't get digested. Most seeds when you chew on them are bitter because you are tasting the toxins. It's a defense mechanism plants do in order to ensure their 'baby' survives. Which is why animals also excrete these seeds whole.
Canola seeds are not edible for humans to begin with. Processing it into oil and calling it edible doesn't make it edible. Canola oil is processed garbage, not processed food.
Milk is edible. Cheeses and butter are made by processing milk. Cheese and butter are processed food but there's nothing inherently toxic about these products. If you can drink milk on its own then you can eat whatever processed products comes from it. The only way you can get the milk to be toxic is to get the cow to be sick.
Oreos aren't processed food because it's not food. Oreos are not cookies.
