At the bottom of each thread is a keyword search function for that particular thread. Typing "pumpkin seeds" in that keyword search returns a lot of hits showing that pumpkin seeds do block 5ar. It also appears that they are high in zinc.

This keyword search function will yield years of research that Lotus has put into her science threads, and in turn is a great service for those seeking information related to our cause.

Best of Luck to You.
