Answer 1

my thoughts, humans are most resistant to elements ingested in small amounts on a regular basis. “small amounts” can be subjective to the individual based on parentage, environment, and personal history etc…example – my younger brother (an idiot by many standards) was at one time, allergic to peanuts, however, after eating peanut butter cups for years, now suffers no allergic reaction to peanuts.
