 [ Symptoms ] you asked my son is 6 year old he do not like to eat those food which taste sweet is there any disorder in his taste bud [ Disease ] i think it depends on his eating overall if he eats a variety of food but just does not like food really sweet that may simply reflect his personal preferences but if he eats very few foods it could indicate a sensory issue or that he is super taster not serious    just more sensitive to the tastes in food if you feel his nutrition and growth is affected see his pediatrician for a referral to a feeding therapist who can help you figure out what is going on good luck
