I grow dwarf stringless green beans in my veg patch and couldn't do without them. As a paleo living in Australia I have pointed out elsewhere that our local paleo people (aborigines) ate quite a few varieties of legumes.
Still do.

The paleo diet "plan" states that early humans wouldn't have eaten legumes because many varieties were poisonous and they wouldn't have had the expertise to detoxify them.

Aussie aborigines, in only 60 thousand years, have managed to find ways of detoxifying lots of native foods, so I think that our ancestors of a million years would have done similarly.

However, in agreement with the previous post, I draw the line at cans and cans of baked beans in tomato sauce!!
