April is #NationalSoyMonth. There are many forms of soy: Tempeh, Tofu, Edamame, Unsweetened Soy Milk and Soy Sauce. I'm sill asked if it is safe - especially for estrogen-receptor positive breast cancer. The answer is yes! The phytoestrogens in soy are structurally different and weaker than human estrogen and don't turn into estrogen when consumed. Moderate intake does not cause cancer growth and is safe for individuals with cancer.
Research around concentrated soy supplements (bars and powders) is less clear. In general, supplement use during cancer treatment is something that should be discussed with your care team. Soy supplements are something those with hormone sensitive cancer should discuss prior to use.
Tempeh and tofu keep for quite a while in the fridge and both are great additions to stir fry and soup. Edamame makes a great snack with hot sauce! I recommend unsweetened soy milk. Those wishing to avoid GMOs should purchase organic.
