The testing done on rats is interesting, but I know that it doesn't expose the whole picture when it comes to humans. There is no telling how it affects humans in addition to physical illnesses such as cancer. Could it also contribute to the increase in children with special needs? Autism is on the rise. Other varying disabilities as well. I do wonder about all the long term (and even short term) effects due to what we are eating, breathing, and environmentally exposed to. And I believe that the big corporations producing these products probably DO KNOW how bad they might be, but safety may not be their top priority. Profits vs safety? The successful lawsuits concerning cancer do speak for themselves. There is so much we are unaware of, but any one paying attention has their suspicions.
