What do you mean with processed foods in this context? Cheese or bread is a processed food too, as are all canned goods, fermented stuff like sauerkraut or kimchi and even canned vegetables.

As a laymen it’s incredible hard to understand what these scientific blokes even mean. All that scientific gibberish means nothing if the very start is so dumbed down you don’t even know what kind of foods they are talking about.

??? Your comment is partially garbled grammar, but additionally cheese contains casein, so how is casein sinister but cheese good?
