Episode notes

There's actually less misinformation than there was five and ten years ago because all these human studies have been published. Most of the time now when you see blog posts or any kind of article for the general consumer on soy and breast cancer, I think most of the articles now highlight the fact that although we used to think soy might be harmful to breast cancer patients or high risk women, that's no longer the case.

Episode #258. Join me as I sit down with renowned soy expert Dr Mark Messina to clear up misconceptions and address concerns about soy consumption. We dive deep into isoflavones, how much soy you can safely consume, and soy’s safety in relation to male feminisation, breast cancer, and thyroid function.

If you’ve been hesitant about incorporating soy into your diet, this episode is packed with essential information you need to make an informed choice.
