BPA (Bisphenol A), is a compound that is used to solidify some plastics and make them more stable and durable.
So why are we talking about it?
BPA can be leached, particularly when heated. If the plastic is a milk jug, baby bottle, or any other container that is holding food, it would be likely that the BPA is leaching directly into the food people are consuming.
How do I know if my container contains BPA?
Look for a symbol on the plastic. It will be a triangle made out of arrows (the recycle symbol) and it will have a number in the middle of it (see picture to left for example).Types 3 and 7 plastics are known to possibly leach BPA.
Why do they still sell foods in these containers if it is so dangerous?
Many countries have banned or are in the process of banning this substance from baby bottles and the like (see this Wikipedia article). It has been suspected to be hazardous to humans since the 1930's.
The Lang Study (published September of 2008) found evidence that exposure to BPA is strongly associated with heart disease and diabetes.
Can I just buy stuff not in plastic types 3 and 7?
Yes, if your aim is to stay away from BPA. However, you should be aware of the issues with the following plastic types:
Type 1: With repeated use, studies show that plastic type 1 can leach DEHP, which is a probable human carcinogen.
Type 6: Can leach styrene, which has been dubbed by the EPA as a 'suspected carcinogen'.
So what's safe?
Types 2, 4, and 5 plastics are considered safe for food and drink storage. But if there's any doubt, you can always use glass.
