I see, with the fussy eater point. Your food list up there sounded like a lot of fat, salt, and sugar so thought that might have something to do with it. Still think it might.
How can it be that if I've been the same throughout my life?
Obviously that can make me even more likely to want sugary foods now, but that can't be the reason I like them in the first place
Soph a great way to get fruit inside you is to make smoothies, you can literally bomb your five a day in it and drink it down in one go.
As for vegetables , soups are a good way to get them inside you too.
You could also try making chinese food at home as you seem keen on it.
As for what Jack is saying , my interpretation was that you've gotten used to eating that stuff for so long , that you don't want to eat other stuff , happened to me with instant noodles , hence why I am a stick figure.
