Soy and Breast Cancer – Exploring the Research
If you’re a breast cancer survivor, you may be feeling some confusion around soy and breast cancer. This is a topic that I am often asked about and leads to much discussion.
Exploring the current research and latest nutrition studies can help you decide to include and ultimately enjoy this healthy plant protein in your diet.
Soy and Breast Cancer Study
The latest study on soy and breast cancer (study abstract) included 6,235 American and Canadian breast cancer patients from the Breast Cancer Family Registry. By looking at this diverse population of over 6,000 breast cancer patients, the researchers specifically analyzed their soy intake. And the results were pretty amazing.
Here’s a summary of the top takeaways:
Breast Cancer Prevention and Soy
Studies also show that eating soy can help prevent breast cancer in women of all ages. Researchers found that soy consumption cuts breast cancer risk by 41 percent. But here’s the catch––it can’t be just any type of soy.
To eat soy for its preventative benefits, it has to be the less processed versions, such as tempeh, miso, edamame, and non-GMO tofu.
Prevention is also linked to how long you’ve been eating soy. Asian women have the lowest incidence of breast cancer, most likely from eating soy during puberty when breast tissue was forming. However, it could be worthwhile to add some unprocessed soy foods to your diet, even if you’re past puberty.
Including organic soy in one’s diet provides more variety and protein options. There are also just so many great dishes and recipes you can make that include healthy soy options!
