What is BPA, why are we concerned about it and how can you lower your exposure to it? Many reusable water bottles, some baby bottles, and clear plastic storage containers are made with polycarbonate plastic containing BPA. The health issue buzz focuses on BPA, a chemical which mimics or acts like the hormone estrogen and is referred to as an endocrine disrupting chemical. Animal studies have found that BPA is linked to abnormal development of reproductive systems and precancerous lesions. We don't have studies in humans but some researchers feel the same potential health problems seen in animals may occurs in humans along with others including the early onset of puberty and perhaps developmental problems.

You can try these tips to help reduce your exposure to BPA.

1. Use plastics marked BPA-free or opt for stainless steel, glass or porcelain. Remember, you can email or call the manufacturer too if in doubt.
2. To prevent BPA from seeping into food and liquids, wash plastics by hand instead of in the dishwasher even if the container says dishwasher safe.
3. Also, forget about using plastics in the microwave and go with glass or porcelain that's made especially for a microwave.
4. This also includes plastic wrap for a cover. Use glass, paper towel or wax paper as better alternatives.
5. Try to avoid those white clamshell take-out containers. Both plastic wrap and these containers contain other plastics that may be problematic.
6. Try to stay away from #7 on the bottom of containers in terms of recycling unless the items say BPA-free. Choose #1 or #2 instead which use products abbreviated PETE and HDPE. At this point these options appear to be better for both health and recycling although not great for the environment.
7. Choose glass or BPA free infant formula bottles.
8. Select fresh or frozen foods over canned unless you find a manufacturer that uses an alternative to BPA in the lining. Eden Foods is one company that does this now and hopefully there are more who will follow. Also look for shelf stable cartons, pouches, bags and cups as alternatives to cans.
