Fava beans contain little L-dopa. I recall much chatter here about fava beans since this list began in 1994. And each round of chatter resulted in the facts that fava does containg more L-dopa than other plants, and that historically it has been known to relieve symptoms in the elderly; but, to get 100 mg. of L-dopa, you'd have to eat many pounds--a poor choice for a complete treatment plan. In general it was okay to incorporate in the diet if it doesn't affect your bowel gas or movements.
