Moms may have been telling their kids to drink their milk for decades, and they’re not completely off base. They just need to specify what kind of milk they’d like their children to be drinking. Based on a new study, your best bet is soy. The journal Cancer Epidemiology, Biomarkers and Prevention reported that adults who consumed soy at least once a week when they were children were 60 percent less likely to develop breast cancer. Didn’t get started on soy until later in life? Not a problem! Even adults who consume soy regularly are significantly less likely to get cancer. So go ahead and enjoy some soy.
