You can't have a long term study given that PTFE doesn't stay in the system, so there's nothing to study.

Are you planning on feeding people PTFE every couple hours?

> the long term effects of ingesting PTFE on the body are unknown.

They are known. They are non-existent.

You are arguing from bad faith and profound lack of knowledge of chemistry. To even hypothesize that PTFE can do anything, anything at all, to the body would require some new magical chemistry that doesn't exist.

There is nothing in the body, nothing, that can affect the stability of the chemical bonds that make up PTFE - if you had even a tiny bit of scientific understanding you know that, and not embarrass yourself with these demands for studies.
