Let's say a food manufacturer finds a chemical that is tasteless but addictive and starts adding it to all their food. Would you also argue that this is very clearly food the people want to consume?
We have ingredients lists on packaged processed food, but we have more than that: the ability to buy ingredients, learn recipes, make recipes, and cook.
We should have the ability to put what we choose (and omit what we don't) in our feeds.
We should have the ability to control it all, though.
