Under ideal conditions pure gold is not toxic because the human GI tract does not chemically react with pure gold. Pure gold become reactive to human GI tract under a variety of conditions from certain food/drug combinations that alter GI tract chemical sensitivity, certain microbial interference, and reactive impurities in the metal. Once gold becomes poisonous it is extremely toxic due to its density and persistence in the body where gold poisoning is similar to lead poisoning but substantial more severe. There was even a HouseMD show episode where a woman was poisoning her husband with trace amounts of gold. The show is complete fiction but the chemistry is accurate. Why take that risk? If you want to knowingly eat poison I recommend cyanide. It has a wonderfully sweet and nutty flavor profile and is incredibly cheap and common. The most common nutritive source is peach and apricot nuts. Furthermore, the human body requires trace amounts of cyanide for microbial interactions to form vitamin B12. Gold has no nutritional value.
