I remember reading that when they were first brought to Europe via the Columbian exchange people were reluctant to eat them fearing they were also poisonous. Now it's hard to imagine, e.g. Italian cuisine without tomatoes.
As a bitter taster it doesn’t matter how much sugar you put on the tomato it’s still too much. About the only thing IMO that you can put on a tomato to make it acceptable is a bacon cheeseburger.
