Bitter tastes. As most kids, I couldn't stand anything bitter. Started out drinking coffee in my teens with 2 sugar cubes and a lot of milk per cup , gradually decreasing to 1 cube per cup, half cube per two cups to zero now. For milk: ~2 tbsp milk if bad coffee, black if good atm. Always enjoyed vegetables though, mostly because at the buffet-style school lunch I had from first grade to graduating high school vegetables was the first thing you were presented with, so everyone piled on some because everything looks appetizing when you're hungry. Made use all get used to veggies.
