In general humans eat everything and in general it kills them.

Others will detect these poison foods and reject them or struggle with them.

The truely healthy person will throw them all up and allow no poisons to enter, this is why so many babies puke and puke until harmed enough by their parents that they can not fight the bad foods.

Your problem would nothing more than correctly the digestive system by the proper fasting/deworming etc. that this entire forum talks about. All the reasons you are this way are not important, unless your poisoned via tooth metals, etc. and refuse to correct the past problems.
