If by "scientific" you mean *good* science (as opposed to the "junk
science" that infests the Internet and mass media), the answer is "no."
Basically, take good care of yourself (healthy diet, healthy weight,
don't smoke, exercise regularly, etc., etc., etc, blah, blah, blah) and
you'll stack the deck in your favor. If you neglect your general
overall health, you neglect your immune system, and no pills or potions
will take the place of good all-around healthy lifestyle habits.

Antibiotic resistance is not "temporary." Once bacteria develop
resistance, they pass it on to their offspring, and so on and so on.
Resistance doesn't disappear unless the resistant bacteria themselves
disappear.

False.

"Yes" to that last part.

Theoretically possible, but statistically improbable. Resistant bugs
spread the same way nonresistant bugs spread. They're just harder to
kill.

There seems to be a misunderstanding of whether we are referring to
bacteria themselves losing resistance, or to individuals losing
resistant strains.

He should say, "...the body loses its natural dwelling
antibiotic-resistant bacteria..."
