Is it true that fluoride can increase hip fractures?

Yes. According to Dr. J. William Hirzy (vice-president of the NFFE LOCAL 2050, the union representing all scientists at the EPA, Washington, D.C.) there have been 5 epidemiological studies done since 1990, in three different countries, all showing a higher increase in hip fractures in fluoridated communities.

Some studies have indicated a 87% higher risk of hip fractures to the elderly in areas where water fluoridation was even below 1.5 ppm.
