Runner beans - poisonous?

[AllyJU]

I've just read something saying that runner beans and french beans are poisonous if eaten raw.
We grow both in our garden and my kids regularly eat them raw with their lunch as well as helping themselves to them straight off the plant. Am I killing my kids by letting them eat them this way?

yes, all beans are poisonous raw.
not too badly, might get dizziness or the runs/vomiting.
we have a strickt 'no picking no licking' pollicy for outside.

peas can be eaten raw though
