The human immune system is capable of breaking down any substance
the verdict
REFUTED
the evidence says no
confidence 7/100
The claim that the human immune system can break down any substance is false, as many nanomaterials, foreign cells, and persistent toxins resist complete degradation and clearance by immune mechanisms.
