On the theme of "all things in moderation"...
I've just learned that green beans contain the same toxins and anti-nutrients as dried beans, when raw. The quantity is much, much less, and I'll still eat fresh young beans from the plant when I get the chance. But I won't be putting a lot of them in my green smoothies every morning.
I'm guessing this is the cause of the slight burning sensation I get from the very long green beans that are commonly eaten raw in Indonesia (pictured).
I wrote this up on Appropedia's "green beans" page:
Mildly toxic when raw. It's a wiki, so if you have any more info, please click edit on that page and type away...
