Summary
Hey! I'd love to hear your thoughts, send me a voice note. Are pumpkin seeds messing with your hormones? A viral claim says yes, and it comes with studies attached. So I tracked them down and read them. What I found: a test on cancer cells in a dish, a study on rats with their ovaries removed, and a computer simulation.
