While reading an article that listed foods that have high levels of
umami, I realized that I have definite reactions to all of them. They
range from mouth sores and headaches (Parmesan and MSG) and general
itchiness/twitchiness, to lifelong avoidance behavior because I
dislike the taste (mushrooms, grapefruit and cheeses in general).
Problems with these foods have increased as I've aged.
Has anyone else noticed this type of thing?
(I'm 51, female, and of mixed northern European descent, if anyone's
keeping track.)
