Should we be concerned about plastic water bottles?

BPA- the controversy.

There continues to be an interesting discussion regarding Bisphenol-A (BPA).  Should we be concerned regarding plastic wrap, tupperware, and water bottles?

BPA is a chemical contained in some plastics--many of the food-grade plastics we use daily.  I've found this discussion on NPR's science Friday to be extremely helpful in continuing the discussion.  It's important to remember how challenging known toxic substances are to evaluate--unknown (like BPA) are likely to be a point of challenge for years to come.

My advice:

• limit contact by using glass or metal bottles.  Stainless steel bottles are available everywhere
• avoid reheating food in plastic.  It tastes better on a plate
• use glass or BPA-free baby bottles for infant feeding
