Soy can be good for you, but be careful how much you intake depending on your potential cancer risk. Soy contains isoflavones, several phytochemicals and plant-based estrogen, which have been linked to decreased risk of hormone-dependent cancers such as breast or endometrial cancer.
However, high doses of soy could actually elevate cancer risk for women at-risk for estrogen-responsive cancers, such as breast cancer. Women at-risk or who have breast cancer should consume only moderate amounts of soy foods as part of a healthy, plant-based diet. They should not ingest high levels of soy in their diet or take concentrated sources of soy, such as soy-containing pills, powders or supplements containing high amounts of isoflavones.
Consume modest amounts of soy foods as part of a healthy plant-based diet, either within your diet or as supplements.
