An article in the journal
Vaccine said the site "tend(s) to not only spread irresponsible health information in general (e.g. discouraging
chemotherapy or radiation for
cancer treatment,
antiretrovirals for
HIV, and
insulin for diabetes), but also have large sections with dubious information on vaccines." According to John Banks, Adams uses "pseudoscience to sell his lies" and is "seen as generally a quack and a shill by science bloggers."
Steven Novella of
NeuroLogica Blog characterizes Adams as "a dangerous conspiracy-mongering crank" and called
Natural News "a crank alt med site that promotes every sort of medical nonsense imaginable." Novella continued: "If it is unscientific, antiscientific, conspiracy-mongering, or downright silly, Mike Adams appears to be all for it—whatever sells the "natural" products he hawks on his site." Peter Bowditch of the website Ratbags has criticized the site, referring to it as a "cesspit" and in 2011 and 2015,
Brian Dunning listed
Natural News as #1 on his "Top 10 Worst Anti-Science Websites" lists. Other individuals who have commented about Adams' website include astronomer and blogger
Phil Plait,
PZ Myers, and Mark Hoofnagle. In February 2014, Brian Palmer, writing in the
Daily Herald of Arlington Heights, Illinois, criticized the site's promotion of alternative medicine treatments, such as bathing in
Himalayan salt and eating
Hijiki seaweed, and referred to the claims
Natural News made about their efficacy as "preposterous." In August 2014, Nathanael Johnson, writing for
Grist, dismissed
Natural News as "simply not credible" and as "nothing but a conspiracy-theory site." On December 8, 2016, Michael V. LeVine, writing in
Business Insider, criticized the site as part of a scientific
fake news epidemic: "Snake-oil salesmen have pushed false cures since the dawn of medicine, and now websites like
Natural News flood social media with dangerous anti-pharmaceutical, anti-vaccination and anti-GMO pseudoscience that puts millions at risk of contracting preventable illnesses." == Notable claims and content ==
