Every plant is trying to kill you. It doesn't want to be eaten. It especially doesn't want you to eat its seeds. We can detoxify most of the ones that people eat, but it costs

Eating the same plants over again can make you sick

You may not be as good at detoxifying those plants as the people who do well eating them

I know I'm a lot healthier with no plants in my diet than I have been with lots of plants
