To find the Wizard of Oz, Dorothy and her friends followed the yellow brick road, defeated a wicked witch, and pulled back a green curtain.

To see The Dr. Oz Show, all you have to do is watch television on a weekday afternoon.

But somebody still needs to pull back the curtain and reveal the truth behind the nonsense.

At least that was my conclusion after catching an episode last week on genetically modified food. Although Dr. Oz made half-hearted gestures toward fair-minded balance, he let his program become a soapbox for wild accusations, unsubstantiated claims, and hysterical advice.

By the end, डॉ. Oz was warning viewers not to eat any canola, मक्का, papayas, सोया, or sugar beets grown in the United States because they may be products of biotechnology. His show turned into an infomercial for Proposition 37, a badly flawed anti-biotech ballot initiative that soon goes before California voters.

डॉ. Oz is Mehmet Oz, a medical doctor who became a television celebrity for his guest appearances with Oprah Winfrey, Larry King, and others. तीन साल पहले, he launched his own show and now millions of viewers tune in.

Sometimes they receive sound medical and nutritional advice. Other times, तथापि, they hear about quack therapies such as energy healing or obtain instructions on using psychics to communicate with dead people. Oz is a two-time recipient of the Pigasus Award, a tongue-in-cheek prize whose purpose is to expose media frauds and junk-science peddlers.

Im not a physician, but my advice is only to watch Dr. Oz with a heavy dose of skepticism.

I had taken a personal interest in the October 17 show because I had been invited to appear on it, and was looking forward to describing the benefits of 21st-century agriculture to a general audience.

Alas, the producers called back and said they didnt need me. One of the iron laws of talk-show television is that you cant be sure youre on until youre actually on.

Yet I still want to say my piece. People need to know the truth about biotech cropsand much of what they heard from Dr. Oz was false.

Ive been farming in Iowa for four decades, and Ive seen agriculture evolve in countless ways. के बारे में 15 बहुत साल पहले, I started to grow GM plants. I witnessed the benefits immediately as my yields went up. I grew more food on the same land and did it with fewer chemical sprays. This is sustainable agriculture at work.

The benefits became even clearer this summer, during the drought. If it wasnt the worst dry spell Ive endured, it was the second-worst, following the one we suffered in 1988.

That year, I eked out just 93 bushels of corn per acre. This summer, I grew about 200, even though rainfall levels were the same.

The difference between then and now is the minimum tillage methods we use and the GM crop technology we have access to. As plants, theyre stronger, healthier, and just plain more robust. Even in terrible conditions, they produce.

If were going to feed a hungry world, we need crops like thesenot merely for farmers like me, but for growers in the developing world.

सबसे अच्छा, GM foods are completely safe. Theyve been tested and retested, winning endorsements from groups as diverse as the American Medical Association and the Food and Agriculture Organization of the United Nations.

Only cranks refuse to recognize this overwhelming consensus. Yet one of Dr. Ozs guests talked like a conspiracy theorist, insulting the conclusions of the AMA and UNFAO as tobacco science and warning of the cover-up.

डॉ. Oz and other anti-biotech crusaders recently have tried to tout a European study that says GM foods cause cancer in rats. Yet they always fail to mention that mainstream scientists have debunked this study thoroughly. Just this week, the High Court of Biotechnology which advises the French Government said the study is flawed.

Now thats a cover-up worthy of the Wizard of Oz.

The real agenda of Dr. Ozs show on biotech food was political. It aimed to promote Californias Prop. 37, a poorly written initiative that threatens to raise grocery-store prices, depress innovation, and pad the pockets of trial lawyers.

Upon pulling back the curtain, we discover that Dr. Oz is no wizard. Hes a charlatan.
