This is from a telecast on BBC in the UK (end 1997).   Research was carried out in a town in US where children born in the 80s and were found to either have very brittle bones and / or did not have teeth even in their teens. Those that did grow some form of teeth, these were black or broken shards.   Over a 10 year research it was found that all the mothers of these children had switched to Soy Milk and products containing Soy rather than Cow/Buffalo Milk.   The research/video and data were shown once when I saw it, the news was sadly conveniently not reported in any other media and has not seen the light of day in any other news. PROBABLY DUE TO COMMERCIAL AND POLITICAL PRESSURE?
