I heard that soy causes breast cancer. Can I safely eat tofu, tempeh, and other soy products?

Several years ago, when Susan started eating mostly (often entirely) plant-based protein sources, she was concerned about whisperings she’d heard about soy “causing breast cancer.” Susan did some research on the topic and found this article.

It doesn’t give an overview of the benefits of soy; it simply addresses that one question. Based on the information provided there, Susan determined to her personal satisfaction that soy is healthy and not likely to increase her breast cancer risk. But it’s a vast and complicated literature—you can read it and decide for yourself.

Susan typically eats 1-2 servings of soy every day. It’s a big part of her diet and she finds her body loves it. This article summarizes many of the health benefits of soy. Again, it’s a large and complicated literature, but if you peruse the articles cited here, you’ll get a sense of why Susan includes it so heavily in her diet. Note: Susan eats only non-GMO soy.
