 You know Dr. Oz. He has a popular show where he dishes medical advice, some of which has earned him criticism. But he's not just a television host: Dr. Mehmet Oz is also a cardiothoracic surgeon who holds the surgery department vice chairmanship at Columbia University's medical school. 
 
 That Columbia affiliation doesn't sit well with some doctors, 10 of whom from various institutions sent a letter to Columbia's dean of medicine, Lee Goldman, calling for Oz's dismissal from the school. His position at "a prestigious medical institution," the doctors wrote, is "unacceptable."

 "We are surprised and dismayed that Columbia University’s College of Physicians and Surgeons would permit Dr. Mehmet Oz to occupy a faculty appointment, let alone a senior administrative position in the Department of Surgery," reads the letter. 
 
 On Friday, Oz defended himself. 
 
 "I bring the public information that will help them on their path to be their best selves," Oz said in a statement, according to USA Today. The newspaper reported that the statement was released by a "Dr. Oz Show" representative. "We provide multiple points of view, including mine, which is offered without conflict of interest," the statement continued. "That doesn't sit well with certain agendas which distort the facts." 
 
 Oz has come under intense scrutiny -- including a congressional grilling -- for pitching questionable weight loss schemes and other medical guidance. As The Post's Abby Phillip wrote last year: 
 
 In the letter to Columbia's Goldman, sent via e-mail this week by Dr. Henry I. Miller of Stanford University's Hoover Institution, the doctors refer to Oz warning his viewers about arsenic in certain apple juice brands and other stances he has taken.

 "Dr. Oz has repeatedly shown disdain for science and for evidence-based medicine, as well as baseless and relentless opposition to the genetic engineering of food crops," the letter states. "Worst of all, he has manifested an egregious lack of integrity by promoting quack treatments and cures in the interest of personal financial gain." 
 
 Representatives from "The Dr. Oz Show" initially referred The Post to Columbia's office of communications. 
 
 Columbia University Medical Center spokesman Doug Levy wrote in a response to Miller and the others: "As I am sure you understand and appreciate, Columbia is committed to the principle of academic freedom and to upholding faculty members' freedom of expression for statements they make in public discussion." 
 
 Miller responded to Levy that "freedoms end where patient safety begins, and Oz's promotion of worthless products that might have side effects and that delay patients' seeking safe and effective therapies threatens public safety." 
 
 Oz is also a Columbia University professor of surgery and directs the New York-Presbyterian Hospital's Cardiovascular Institute and Complementary Medicine Program.

 The physicians' letter to Columbia also took issue with Oz's "baseless and relentless opposition to the genetic engineering of food crops." 
 
 In his statement, USA Today reported, Oz responded: 
 
 "I do not claim that GMO foods are dangerous, but believe that they should be labeled like they are in most countries around the world." 
 
 He added: "I will address this on the show next week." 
 
 Here is the whole text of the letter. Two additional New York doctors also wanted to sign after the letter was sent, Miller said: 
 
 Lee Goldman, M.D. 
 
 Dean of the Faculties of Health Sciences and Medicine 
 
 Columbia University Dear Dr. Goldman: I am writing to you on behalf of myself and the undersigned colleagues below, all of whom are distinguished physicians. We are surprised and dismayed that Columbia University's College of Physicians and Surgeons would permit Dr. Mehmet Oz to occupy a faculty appointment, let alone a senior administrative position in the Department of Surgery. As described here and here, as well as in other publications, Dr. Oz has repeatedly shown disdain for science and for evidence-based medicine, as well as baseless and relentless opposition to the genetic engineering of food crops. Worst of all, he has manifested an egregious lack of integrity by promoting quack treatments and cures in the interest of personal financial gain. Thus, Dr. Oz is guilty of either outrageous conflicts of interest or flawed judgments [sic] about what constitutes appropriate medical treatments, or both. Whatever the nature of his pathology, members of the public are being misled and endangered, which makes Dr. Oz's presence on the faculty of a prestigious medical institution unacceptable.

 [This post, originally published on April 16, has been updated.] ||||| Dr. Oz is America’s trusted television doctor. Though his expertise is cardiac surgery, the Dr. Oz Show covers myriad subjects and tops ratings, with millions tuning in daily to heed his advice. The man has charisma on his side; his demographic is composed largely of adoring women and young mothers. Though mainstream media has slammed him for espousing anti-science views, Oz continues to promote non evidence-based health advice. He’s truly earned the “Snake Oil Salesman” title, and continues to uphold the quackery that led to the label. Indeed, a recent study found that about half of the medical advice on the Dr. Oz show is baseless or downright wrong. 
 
 In addition to baseless medical advice, Oz instills fear of genetically-engineered foods, though the world’s leading scientific organizations agree that GE techniques are inherently safe. 
 
 On his March 10th episode, Dr. Oz aired a segment on the Arctic Apple. The United States Department of Agriculture and the Food and Drug Administration recently approved and deregulated the genetically engineered apple after years of field testing. Engineered with an enzyme “off-switch” using a technique called “RNA interference,” Arctic Apples don’t brown or bruise when cut, bitten, or bumped. The television doctor treated the topic with his usual anti-GE sentiment. I’m a 32-year-old mom of two, and I fit solidly into Dr. Oz’s target audience. But I’m not biting when it comes to his take on Arctic Apples, or most of his drivel in general. 
 
 I took one for the team and watched that episode, titled ““The Non-Browning GMO Apple: Is It Safe?” I then co-authored a piece on the episode for Slate (check out the comments, lots of positive ones as well as a few typical cases of Shill Accusation Syndrome.) Following the relative success of our article, “Low-Hanging Fruit: Dr. Oz sows seeds of mistrust on genetic engineering” my co-author Dr. Henry Miller coordinated a letter from himself and fellow esteemed physicians to the dean of the medical school at Columbia University. Dr. Mehmet Oz holds a senior appointment there in the Department of Surgery. 
 
 The letter reads as follows: 
 
 Lee Goldman, M.D.

– Celebrity TV doctor and magic bean salesman Dr. Mehmet Oz also has a prestigious post at Columbia University, which some esteemed colleagues in the medical world find absurd. In a letter to the dean of the Columbia University medical school, where Oz is vice chairman of the surgery department, 10 doctors call his presence on the faculty "unacceptable," citing his "disdain for science and for evidence-based medicine," and accusing him of displaying an "egregious lack of integrity by promoting quack treatments and cures" for financial gain, Skepchick reports. Oz, the doctors write, is guilty of "either outrageous conflicts of interest or flawed judgements about what constitutes appropriate medical treatments, or both." Dr. Henry Miller of Stanford, the first doctor to sign the letter, tells the New York Daily News that Oz is "a quack and a fake and a charlatan." He says Columbia only has him on the faculty because "they're star-struck"—and may be "hoping Oprah will come and endow a center for homeopathic medicine." In a statement, a Columbia spokesman says, "Columbia is committed to the principle of academic freedom and to upholding faculty members' freedom of expression for statements they make in public discussion," reports the Washington Post. A recent study found that about half of what Oz says on TV is wrong, which Matt Novak at Gizmodo says proves that calling the doctor "full of s---" isn't just opinion—"it's science!" (More "down with Oz" news here, here, and here.)
