It all taste so gross.

I was never raised up on fruit or vegetables. My grandma raised me, and while I love her to death, she was a push over. She let me eat snack after snack and junk food after junk food. The only healthy thing I consume is water. That's all I drink, but now I want to eat healthier and take better care of my body. Every time I try to eat vegetables or fruit, I want to puke. I don't know how to make them good. I even tried to add sauces with them, such as carrots and ranch or carrots and barbeque (never again with barbeque btw). I just want to eat healthy, but none of it tastes good. I am also allergic to some fruit, so my options are limited, such as pineapple, pears, etc.
