Spencer Abfall Good thinking! They tasted them and decided, "Hm,
   THIS yellow stuff tastes better than THAT yellow stuff. Whether
   or not its good for them or not doesn't matter - it's TASTE..
   and ants DO prefer white sugar over everything - just like
   humans do xD So the idea that ants know what is good for us to
   eat is completely wrong :) yay - thank you Spencer. You have
   taught me something - again! "
