You’d be hard pressed to convince me to consume a class 1 carcinogen in moderation for health benefits.

Class 1 just means "confirmed" with absolutely nothing stated about what the risk level is. You'd be hard pressed to convince me to make any decision based on that alone.

Cell byproducts are known carcinogen, and definitely ingested for health benefits (not for themselves, but en masse).

Sunlight is a class 1 carcinogen too. Dracula is the only person that avoids it.
