I love mushrooms and black olives. My girlfriend hates them. She also hates eggs, most styles of beef, and a host of other things. I, in fact, will enjoy just about anything.
Why? Is there some advantage to having a species with varied tastes like this? I would think that it makes more sense for the body to be set up as “good for you = tastes good” and “bad for you = tastes bad” to ensure that the species gets its round of nutrition and isn’t lacking in some vitamin because members don’t like brussel sprouts. Is there some biological component to us (or any other animals) that determines what will be yummy and what will be ignored so we can eat more Ben & Jerry’s?
