Actually went into a deep dive on food eating for a week or two. The competitors I watched videos about or interviews with claim they don’t intentionally make themselves throw up because that primes their gag reflex to be more comfortable with throwing up in general, which obviously you don’t want as a competitive eater.
Makes sense.
I cannot imagine how impossible foods plant “meat” could possibly be more toxic than traditional hot dogs, and obviously they conform to the same food production safety standards the FDA sets.
