Basically, it’s best to use as much
organic, “free-range” food as you can afford. And if you drink
coffee or tea, make sure you only buy the organic versions: Commercially grown coffee and tea are some of the most pesticide and herbicide contaminated crops in the world. Also be sure your drinking water is as pure as possible. Filter out chlorine and other additives, and if possible fluoride, too, although that requires more expensive technology.
