I love broccoli now. It is one of the most nutritious of vegetables.
But as a kid I hated it. My mom would serve things I didn't like very much. I hated coliflower, cabbage, rutabagas, turnips, lentils.
I refused to eat grapefruit unless it was pink. Once when I was 8 years old, my mom served me a half grapefruit that wasn't pink. I insisted that I wouldn't eat it unless it was pink. She told me to hide my eyes and count to 10. When I looked up the grapefruit was pink! I ate it and enjoyed it.
She kept a box of assorted food coloring in her cupboard.
