Nose / Olfactory is the other part of taste, to blend in the brain for the actual flavoring sense of savory sensations spiciness, aromas, etc.

75% or so is Olfactory - basics of bitter, salty, sweet, etc are tastebuds/tongue or around 25%.

Meds take away most Olfactory stuff, or take away taste bud stuff.

Genetic loses can be one or other, and adaptations come during development; but mostly foods are sorta bland compared to others without those loses.

Literature is available to check.

Head trauma has been reported to affect taste in one way or another; but most reports are or have been reported to be from those meds we take relating to our injuries.
