Q: I have recently heard concerns about boys eating soy. As the mom of one vegetarian boy and with another boy on the way, I’m worried about their development and long-term health. What’s the truth surrounding these warnings? – Michelle, Phoenix

A: Soy contains plant estrogens, so there are concerns about the health effects on babies of both sexes who are given soy infant formulas. Part of the issue is that there’s not enough good data, which always leaves the door open for doubt and rumor.
