The current (October 2006) issue of National Geographic has an EXCELLENT article about environmental toxins (including ones that end up in the food supply.) I very strongly urge anyone who can read to find a copy of this one and check it out, thoroughly. The article is called "The Chemicals Within Us." The types of chemicals, where they come from, and what they do in your body are all discussed. It is interesting, and a bit frightening. Can you guess which one is used routinely in almost every shampoo to "improve the texture and consistency"? Which ones can leach out of the plastic bottles your favorite "healthy" bottled water comes in, or how quickly it is absorbed into the water? Which ones mimic estrogen-like compounds and how they get into our bodies? Ladies, just because it is "estrogen-like" doesn't mean it's safe for you. Ever heard of DES? Men, do you know what bisphenols can do once you ingest them? Find out.
