How to reduce BPA exposure

Infant formula: Choose powdered versions when possible. Cans of powdered and liquid infant formula are lined with an epoxy made from bisphenol A. But the Food and Drug Administration found that BPA leaches from the linings into liquid formulas, not the powdered kind.

Canned foods: Tests by Consumers Union and the Environmental Working Group found the highest levels of BPA in canned soups and pasta, but it was also detected in canned fruits, vegetables and beverages. When possible, use frozen fruits and vegetables, and buy soups and beverages in glass containers. Cardboard "brick packaging" for soups, broths and tomatoes is another BPA-free alternative.

Plastics: BPA is often found in polycarbonate plastic food containers that are marked with "PC" or with the recycling number 7. Plastics with the recycling label numbers 1, 2 and 4 do not contain BPA.

Water bottles: Some metal water bottles are lined with a coating that contains BPA. Use stainless steel bottles that are not lined or plastic bottles that are clearly marked BPA-free. Avoid old or scratched plastic bottles.

Heating: Avoid microwaving foods or liquids in polycarbonate plastic containers. Use glass or ceramic containers instead.
