Minisode: What's the Deal with Soy? Part 2

from Vegan Boss Radio · host Shawna Barker

Soy is one of the most misunderstood foods out there — even within the vegan and plant-based community. In this mini solo episode, I break down the top myths about soy and share what the latest research really says. From hormones and breast cancer risk to thyroid health, “processed” tofu claims, and concerns about soy and the environment — this episode covers it all. You’ll learn why soy doesn’t increase estrogen or lower testosterone, how it may actually protect against certain cancers, and why cutting it out of your diet could mean missing out on a nutrient-dense, protein-packed food with decades of proven health benefits. Whether you’re still unsure about soy or just need some science-backed facts to share with skeptics, this episode will help you feel confident adding tofu, tempeh, soy milk, and edamame to your meals. Studies mentioned in this episode: 1. Dairy, soy, and risk of breast cancer: those confounded milks 2. Soy Isoflavones and Breast Cancer Risk: A Meta-analysis 3. Systematic Review and Meta-analysis on the Effect of Soy on Thyroid Function 4. Neither soy nor isoflavone intake affects male reproductive hormones: An expanded and updated meta-analysis of clinical studies 5. Clinical studies show no effects of soy protein or isoflavones on reproductive hormones in men: results of a meta-analysis ____________________________________________________________________ 👉 If you’re ready to take the next step in your own nutrition journey, book a free 15-minute discovery call with me to learn more about private nutrition consultations.
