This article appears to be straight out of the "Medical" community.
The information is presented with a particular slant, its "bent" to fit a certain agenda.
The only thing that comes from that source regarding anything natural to the health is "fear".
Its called fearmongering. - Thats whats being pushed is fear.
There is a reason for it and just imagine if everyone did a Master-Cleanse periodically from their twenties on. - There would be no unhealthy people.
The Medical community needs unhealthy people around for its existence.
There is no need to publish that stuff here - plenty of it can be found across the internet.
