Is soy formula as bad for babies as plastic?

With all the news lately about estrogen-mimicking chemicals found in plastics, including sippy cups for babies, it’s been easy to ignore natural sources of potentially similar problems. One such source: Soy found in infant formulas. You’ve likely heard soy isoflavones touted for peri- and menopausal women who are at the end of their major estrogen-producing years. Soy is touted as a way to reduce hot flashes and protect against breast cancer. But those issues don’t concern babies, and researchers have started looking at the effects of soy on young children. Instead, high exposure in kids may lead to early puberty and other problems later in life. So is soy as bad as plastic villain bisphenol A? Scientists disagree. But animals fed the same as babies do show effects, some of them stronger than with the chemical. (Via The Raleigh News & Observer).
