1) Actually, most of what we eat. Try to eat gold: "You can’t eat gold or oil. Well, i suppose you can. At least in trace amounts gold appears to be an essential element and won’t harm you in minute quantities. As for oil it’s used in so many insidious ways, even as food, vitamins and drugs after being rearranged molecularly—synthetically, i suppose you could claim you can (and some do) eat it in a million processed ways. But, obviously, neither will keep you alive and thriving as seeds will. Seeds are something else. Something rare, unique, wondrous and beautiful. Something spectacularly alive, awaiting renewal, a life force of unequaled value. Something magical. Something mysterious. Something beyond human analytical understanding or reductionist scientific thinking or ignorant tinkering. One-eyed observations don’t cut it."

A pound of dry saffron (0.45 kg) requires 50,000–75,000 flowers to make, meaning an entire football field of these flowers. Requiring so much resources and labor, prices for the spice go around US$500/pound to US$5,000/pound (US$1100–US$11,000 per kilogram)."

Soybeans. I'm glad you left out animals. I'm sure many of those who eat a less ethical diet would have mentioned various types of decaying flesh.

Corn. Corn is present in most food we eat, whether it be corn starch or corn syrup. Without corn, don't expect yourselves to be eating manufactured foods such as bagged chips or cereal, etc.
