The basic concept, "put a new compound in everybody's bodies" because it makes them better suited for thier environment is entirely reasonable.

Humans didn't evolve in the context of plentiful food. It's one of the ways our success took us to a place our bodies are maladapted to. Genetic pressures will solve the problem eventually. Memetic measures have seen some success.

Like "flouride in the water", it is going to require a lot of work to justify that "exposing everyone is univerally good" but it is a possible reasonable and safe path eventually.
