George H.W. Bush was obsessive about his hatred of broccoli, he mentioned it 70 times during his presidency, banned it from the White House, and blamed the extinction of the dinosaurs on it.
Broccoli does not exist in nature. Rather, it is a human invention bred out of a wild cabbage plant. It was cultivated to have a specific taste and flavor that was more palatable to people.
McDonalds once came up with bubblegum flavoured broccoli, in an attempt to get kids to eat healthier. It was never introduced as children found the flavour confusing.
