OK, this is only tangentially science related, perhaps.
However, a lot of science goes into today's food. There is a lot of money put into developing and applying techniques to keep food fresh and palatable while traveling and while on the shelf. Some very popular food items are unacceptable to eat toady because of concerns about the impact of harvesting those items on the environment. (I'm thinking primarily of endangered species here, but not exclusively.)

That's a total of 59 for me. Not bad. I had to look up some of these items, only to discover that, yes, I had indeed eaten them without knowing what they were!
To put a science spin on this, it would be interesting to look at the fat content of this list. We love fat and it can play a big role in how well a meal is perceived.
