"Dr. Oz" draws more criticism. Mehmet Oz, M.D., has been blasted again by two critics:
- Benjamin Mazer, a third-year medical student at the University of Rochester, is trying to enlist medical associations to combat the potential negative impact on public health of what he calls Oz's "pseudo health advice." In a recent interview, he described widespread concern expressed by physicians about the harm they see happen day-to-day with their patients. [Meet the medical student who wants to bring down Dr. Oz. Vox, Oct 2, 2014]
- Joe Schwarcz, who directs McGill University's Office for Science and Society, has debunked Oz's dramatic attack on an herbicide designed to kill weeds in corn and soy fields without harming the crops.

Suit filed to block Israel fluoridation ban. Public health and dental experts who oppose Israel Health Minister Yael German's decision to prohibit fluoridation throughout the country have asked the High Court of Justice to overturn her order. The suit charged that German's decision will "cause harm to public health and significantly increase the gap in dental health between the well-off and the poor." [Siegel J. Health Minister taken to high court over prohibition of fluoridation of drinking water. Jerusalem Post, Oct 6, 2014] In 2002, when Israel passed a mandatory fluoridation law, German was Mayor of Herzliya. Shortly after the law's passage, she and others filed a lawsuit to block its implementation. The suit, which was opposed by the Ministry of Health that German now heads, was ultimately dismissed by the Israeli Supreme Court, which concluded that the Health Ministry had responsibility and that fluoridation was safe. The economic disparity was demonstrated by a study conducted in 2011/12 at Jerusalem's Hebrew University. The researchers found that 12-year olds in fluoridated Haifa averaged about 30% fewer decayed, missing and filled teeth than those in non-fluoridated Kfar Saba and that the economically disadvantaged children in Kfar Saba had 26.7% more decay than those from the most affluent backgrounds.

New Zealand court upholds fluoridation law. The New Zealand appellate court has rejected the anti-fluoridation group New Health New Zealand's claim that the chemicals used to fluoridate water are medications. The suit asserted that under New Zealand's Medicine Act of 1981, fluoride added to water is a medicine, which gives citizens a right to refuse "treatment" and mandatory fluoridation should therefore be illegal. The court reasoned that although fluoride is added to domestic water supplies for a therapeutic purpose and fluoridation could be considered a form of administration, the concentration in water reaching the user is far too low for the Act to apply. The plaintiffs have filed an appeal. [Judgment of Collins J. New Health New Zealand vs. the Minister of Health. New Zealand High Court CIV-2014-485-004138, Oct 9, 2014]
Supplement products associated with liver toxicity. The Drug-Induced Liver Injury Network has reported that about 15% of the cases that it studied involved herbal and dietary supplement products. The organization was established in 2003 to identify and study cases of drug-induced liver injury attributable to medications (excluding acetaminophen) and supplements. The 130 patients with liver injury from supplements consisted of 45 (35%) who had taken bodybuilding products and 85 (65%) who had taken non-bodybuilding products. The report noted the problems attributable to bodybuilding products were relatively mild but severe outcomes (deaths and liver transplants) were more frequent among users of non-bodybuilding products than among medication users.
