Moms are worried about a new study linking plastic to diabetes and cardiovascular disease.

It seems like every day we hear something different about the safety of BPA, which is the chemical in plastic.

This week, in the first large scale study of BPA in humans, a team of researchers found exposure to bisphenol A or BPA was associated with cardiovascular disease, type two diabetes and liver enzyme abnormalities in adults.

But today, the FDA defended its assessment that BPA is safe. ''Right now, our tentative conclusion is that it's safe, so we're not recommending any change in habits,'' said Laura Tarantino, head of the FDA's Office of Food Additive Safety.

So what's a mom to do? Momlogic pediatrician Dr. Cara Natterson gives us the bottom line on BPA:

Dr. Cara says, "Whether you agree with how the FDA chooses to make policy decisions or not, one thing is for sure -- more studies need to be done on how BPA affects our bodies."

Do you try to limit your kids' exposure to BPA, or do you think it's nothing to worry about?
