Wild plants are so unpalatable that only people with no other choice, like hunter-gatherers, eat them.

The Hadza people eat wild tubers only when nothing better is available, because they’re not tasty or filling — which supports the idea that wild plants are usually hard to eat without cooking or changing them.

Wild berries have more natural chemicals that make them taste bad or bitter to keep animals from eating them; domesticated berries lost these chemicals over time, making them tastier for people.

Wild corn ancestors have more bitter, toxic chemicals than modern corn to protect themselves; humans bred corn to remove those chemicals so it’s safe and tasty to eat.
