FWIW Just noticed an article that I thought might interest some of you out there. It is from May/12 on Dr. Mercola's site. (mercola.com) He is a medical doctor who really walks his talk. His info is always well researched and if things change, he updates. His mission is to get the info out so you can take responsibility for yourself. His products are great but it is not necessary to purchase in order to get the newsletter. IMHO his video interviews are excellent and all suggestions are worth considering. See how it fits into your belief system and if it makes sense to you.
