We seem to be fighting an uphill battle against Monsanto with their pesticides and the GMO foods vs organic and grown w/o pesticides foods, and the water supply situation, so always drink distilled water, use it in anything you put into your body. Get some kind of filter for your shower head. Chlorine and fluoride are very destructive to the body. Cholorine will kill off all the good bacteria in your intestines, eventually. When the body bathes, it also absorbes huge amounts of these toxic, cancer and disease causing pollutants. If you must use soaps and shampoos, then get some with all natural ingredients, NEVER USE THE ANTIBACTERIQAL SOAPS. We need all the good bacteria on the surface of our bodies and in our colons to counteract all the bad ones.
Do some research on the GMO foods and find a place you can get your organic produce that is grown without fungicides and pesticides. IF you can't grow it yourself. Then do your own preserving. We don't need all that stuff on the inside of sore-bought cans, either, as a poison for the body that do a lot of reacting with acid foods like tomatoes, especially. Very tough to stay healthy in our world like it is today.
