The Germans and Russians use to put fluoride in their prisoners drinking water to make them docile and stupid.  I do not think they were worried about their prisoners oral hygiene.  However today many cities around the world put tonnes of sodium fluoride in drinking water to help prevent tooth decay.  Wow they must be really concerned about my teeth.  Vaccines contain mercury a known toxic substance that can damage neurotransmitters.  Pesticides are sprayed on our fruits and vegetables even when it is now known that many of the chemicals found in pesticides are endocrine disruptors.  These chemical also find there way down to underground water supplies.  These chemicals can be carcinogenic as well.  If these chemicals arm harmful enough to kill bugs, ingesting these chemicals may not be good for our bodies as well.  For every ailment we are prescribed drugs to mask the symptom while pharmaceutical companies make billion off the bad health of the population.   It is estimated that over 300 000 people die from adverse side effects to medication.  In many instances the medication does not out perform the placebo yet it is sold to the people.  Our medical industry is more concerned about drugging the population and profit than it is on creating a healthy society.  If our health system were really concerned about the health of the people who would be promoting a holistic paradigm, a natural heath paradigm in which a healthy diet and a healthy outlook on life would be front and center instead of the pill.
