maybe it was just a bad batch of tofu?
go out and buy and cook a new batch and see if you have a reaction.
actually it is quite hard to know is he got allergy towards the certain food that he eat, atleast he know himself very well. Usually it need to take sometimes to see whether he is good with the food or not for a period of time. Because allergy or bad for his body can be in few stages, the worst case is the body straight away react towards it by come out all kind of weird stuffs, or else the really mild case is he will feel unhealthy, pain in certain part of body, or the body system got some reaction towards it like constipation, acne and all sort. The second is the minor food incompatible, but his body still can live with it, and still can run around, just that his system is not at its 100% performance.
Conclusion is that he might need to take sometimes to eat that food to see whether his body can take it or not, or he might not know he cannot eat that food without realisizing it. In my case, i dint know i cannot drink milk, i had drink it for so the long and only recently i found out that my bowel moment is very bad and can be consider constipation. Until i have to slowly stop one by one for all the food that i eat, at first start with milk, and found that the bowel got a bit better, and second is the whey protein. Now my liver is not feeling as bad as last time. Damn, still got half bottle of ON whey protein with me

My body just too bad and problematic, compare to you guys who can eat anything that you want.
