Soy Consumption Reduces the Risk of Death and Breast Cancer Recurrence

This is a fascinating abstract of a study published in the Journal of the American Medical Association. If anyone you know is a breast cancer survivor you should forward the link to this abstract.
As I mentioned yesterday there are a lot of soy haters that claim that soy increases the risk of breast cancer in some women. This large study (over 5,000 women) found that women that consumed soy (up to 11grams per day) reduced both their risk of death and breast cancer recurrence by almost a third.
According to the Journal, “The inverse association was evident among women with either oestrogen receptor–positive or –negative breast cancer and was present in both users and nonusers of tamoxifen,” they continued. “In summary, in this population-based prospective study, we found that soy food intake is safe and was associated with lower mortality and recurrence among breast cancer patients… This study suggests that moderate soy food intake is safe and potentially beneficial for women with breast cancer,” they concluded.
I am still going to avoid soy protein isolate but this gives me additional incentive to continue to include whole soy (tofu, edamame, and soy milk) in our diet.
