Scared of soy?? Us too.

This episode unpacks the man-boob myth and also looks at the effects of soy consumption on pre- and post-menopausal women.

Justin B grabs a strong Aeropress coffee just before the show - clearly his usual frenetic enthusiasm was going to be insufficient for this one. So we make it rain in the first half of the show as we deliver a some long overdue listener shout-outs, investigate the placebo effect, cross-examine Wim Hof,  discuss the downside of having a twin and castigate Spotify DJs.

Soy chat starts around 29mins.

Jeremy’s Iron is an excuse for two mates to geek out over science, research and publication. It’s a conversation between a biostatistician (Justin Zeltzer) and an orthopaedic surgeon (Justin Bobyn).
