A number of scientific studies suggest a link between soy consumption and reduced risk of certain cancers, including breast1 and prostate.2In Asian populations, which have traditionally consumed soyfoods for centuries, many researchers have noted lower rates of breast cancer. 3 More research is needed to draw firm conclusions about soy and beneficial cancer effects. However, today’s medical and nutrition communities recognize soyfoods like soymilk as a nutritious addition to a healthy diet.
Myth: Soy is not safe for breast cancer patients and survivors.
In fact, the American Cancer Society confirms that breast cancer patients can consume soyfoods regularly.4
