My AH decided to go on this major health kick... Decided that all oils other than coconut and olive oil were toxic and that fructose was bad too because it is processed by the liver. Actually, given how overloaded his liver was getting, it was probably a good idea to lay off the fructose.
But, I really got an eye-opener when he started complaining of heart burn and sometimes nausea. He had been squeezing some fresh limes into juice, added sugar to make it less tart, and copious amounts of rum to make it palatable. He decided he should lay off the limes because the fructose was causing his heartburn. He just swigged straight rum from the bottle after that.
Of course, it's the fructose that is making you so sick. Quack!
