You'd find plenty of definitions if you looked for them

Ultra processed food benefit companies more than they benefit you
Exactly. Terms that are meaningful have one generally accepted definition. When everyone and their brother are coming up with their own pet definitions, that is when a term is considered meaningless.
btw feel free to open a dictionary and discover that a lot of words have multiple definitions, it doesn't mean they're meaningless...
While it is true that words often have multiple meanings while remaining meaningful, they do not have multiple meanings within the same context as is the case here. I am surprised that wasn't obvious to you. Hey, on the bright side, at least you got to learn something new today.
I guess climate change doesn't exist either then. If by everyone you mean everyone except science, then sure, but that's why we have the scientific consensus...
But it is a term that definitely exists. We can find it used often in the literature. Hell, we can find one of those instances in your very own comment... How on earth did you reach the conclusion that it doesn't exist? You didn't give that one any thought at all, did you?
What is this singular, well-defined, and widely accepted definition in science for "ultra-processed food"?
Are glazed donuts ultra-processed foods?
Having a greater number of competing definitions does not generally make a term more meaningful. (Take "art" for example.)
