I saw something about fava beans quite some time ago and discussed them with the wife's neurologist. He was aware of them and possible benefits, buuuuut told us that in order to get any significant effect from them a person would have consume an inordinate amount of the beans. Remember that like all beans these are high in protein and so the question becomes - would the protein louse up any benefit. We tried them for the heck of it, lima beans are tastier.
