how pyschological is our pickiness to food.

[RoadRunner79]

I know when I decided and prayed to like practically like all food, it happened. Before that, I was a very picky eater.  

It really happened to the extent, there isn't any food I have ate from sometime after (like a few months) that day but I enjoy.

Food even that I hated most, are some of my favorites now.

I think there are certainly, some things that are psychological about our eating habits.   Some things might just be our taste buds or the way that those signals are interpreted by the brain.  And I think that someone mentioned, that our tastes can change based on what our body needs. 

One for they psychological side of things that I am aware of for myself.  I used to eat wafer cookies in my school lunches when I was a kid.  (Something like this) I have never gotten stomach flu's and have not gotten sick to my stomach too many times in my life. However this time, these particular type of snacks where eaten just prior to getting sick to my stomach. Probably over 30 years later now, and I have absolutely no desire to eat that type of snacks. Even twix or kit kats are unappealing to me. I also had a girl friend in college, who from growing up on a farm (and seeing the animals slaughtered) could not eat meat (except for taco bell chicken it seemed). It would actually maker her sick, though it was just psychological.
