Words have multiple meanings and that two can use the same word, such as “natural” and each be perfectly valid in our used definitions?
The same is also true for the word “food”.
“chemicals masquerading as food” is a valid statement, for “food” is not only “what chemicals our bodies use”. but it is also the shape and size, the smell, the production, the perception, the recognition.
As is our different uses of the word “natural”. Each are provably regular normal uses of the word.
