There have been all kinds of stories in the news the past few months about BPA (bisphenol A) in plastics that hold food and beverages. This chemical has been linked to reproductive and developmental problems in lab animals.
There haven't been any studies on the effect on humans, though, until this one that is taking place at Harvard right now. It'll be interesting to know the results.
In the meantime, it's probably best to avoid BPA products anyway. These products can be identified by looking on the bottom for the recycle symbol with a 7 in it, or the letters "PC" on the bottom.
So what do you use for your leftovers and your water bottle? In my household, we drink from Sigg bottles (a little expensive, but a good investment and they come in cool designs! I love mine!) and I pack my leftovers and take them for lunch in good old glass Pyrex bowls.
One of the big concerns is the BPA that is in almost all baby bottles. My sister uses Born Free bottles that are BPA free. So while a lot of things do contain BPA, there are alternatives.
