I have no direct evidence of the "Magic Bean" that makes any sense but I must add thst I am on a vegetarian diet and I usually have at least one or sometimes 2 bean meals a day and If for some reason I am negligent for several days I get a lot of rigidity and back pain. For that reason I am convinced that beans have some place in a PD diet. I eat a variety of beans but not much in the fava bean line. Donna [log in to unmask]
