BIsphenol A, or BPA, is a chemical that is often found in baby bottles and even infant formula cans.
According to the National Toxicology Program (NTP), it acts on the brain like a hormone, causing behavioral and developmental problems, early puberty in girls and changes in the prostate and breasts of those exposed. The problem is, we’re all exposed to it—in a study from the Centers for Disease Control and Prevention, 95% of subjects had BPA in their system.
