how pyschological is our pickiness to food.

[Whateverist]

Let's not make it about God. I know right now I enjoy all food I eat.

Food I use to hate, I like.  I think it's psychological.  And we don't know how much control we have and power to change who we are.

I think any advantage found for believers are of a psychological nature, so that -for you- food biases might very well be connected to what you believe about God.  I was an extremely picky eater as a kid but I've become an adventurous eater as an adult.  No god belief involved in my case.  I just started liking new things when others would prepare them and get excited about having me try them.  It did make me question my old food biases.

I know I am free to choose what I like.   I don't believe also that I don't choose who I have a crush on. Sure I don't choose all the chemical reactions that come when you are attracted to someone, but at the end, I decided if I am attracted to someone or not.

I believe choice. Choice is the fundamental thing that makes us human.

But what are your choices based on?  No one is free to choose what it is they will like.  Better to say you are free to question your food preferences and approach new foods with a more open mind.  What you like is something you discover, not something you choose.  Things don't taste the same so there is no justification for thinking you would like everything equally provided you held back your bias.

Most choices aren't apparent. They aren't apparent you've made them. But you have.

I suspect I'm using "biases" where you're using "choices".  But I think it would be a mistake to attribute too much power to choosing.  If you recognize an illegitimate bias, perhaps one acquired through media advertising, you can sometimes work around it.  But once you've removed irrational biases, what you find below is not a blank slate.  What you find is how things actually taste and which ones appeal to you more or less.
