How do I avoid BPA contaminant exposure?
First, watch the heat.
Heating up plastic can cause the material to degrade, allowing BPA to leach out.
Next realize that many plastics contain BPA, so using glass and other containers can help to reduce exposure. Baby bottles and Sippy cups can no longer (legally) contain BPA.
Avoid using the microwave or dishwasher which can heat plastic containers that may contain BPA, and allow it to leach.
Minimize your use of canned foods and canned drinks and look to fresh or frozen choices when possible. Some companies like Del Monte, Trader Joes, Whole Foods and Muir Glen have started to make BPA-free cans.
