Subsitute for Edamame and Black beans?

I'm going on a 90 day meal plan of clean eating and I'm doing some research as to what kind of foods are available in my area. I live in Ireland, so not many 'exotic' foods are available unfortunately, which are probably what a lot of others consider normal. It says I need edamame beans and black beans, neither of which I can find in any health shop or normal supermarket. Does anyone know of any alternatives that could be used in place of these beans? I don't really care if they don't have a similar taste, it's the nutritional values that are more important to me.

I've looked it up and I know I can get red split lentils, aduki beans, whole green lentils, french style lentils, black rice, shelled hemp.

Thanks guys and any other easy to find recommendations would help a lot!
