Found this interesting info on the health properties of fava beans: "The Fava bean, a diuretic, has a long history as a folk remedy, commonly used to treat edema and diarrhea. Beyond any anecdotal claims, there now exists empirical evidence to substantiate the contention that fava beans produce a calming effect. Modern scientific research revealed that all brain activity is facilitated by the neurotransmitter Dopamine, including energy, memory, and sense of well being. As people age, the level of Dopamine in their brain cells declines, impairing brain functions. Pointedly, fava beans contain naturally occurring L-dopa, an amino acid that is a chemical neurotransmitter, which has demonstrated results in preventing and easing the effects of Parkinson's Disease."
beans for the aged It's true they have been doing trials on people with parkinsons with both fava and broad beans, more dopamine in the immature beans and young pods. People with parkinsons taking levadopa need to be careful not to eat broad beans regularly without consulting their gp as it may put their levels up too high. Hopefully when more studies have been done they will be able to eat broad beans or fava beans instead of taking medication. Depends on the severity of the parkinsons of course.
