This is a very good (long) article about how inadequate zinc and high copper levels contribute to PCOS, among other things.

Please note that cacao/chocolate is very high in copper. Hemp seeds are high in zinc and low in copper. A ratio of 7.5 parts zinc to 1 copper is recommended. 40mg per day is considered the tolerable upper intake level for zinc.
