不粘锅涂层使用的是PTFE（特氟龙）分散乳液，因为PTFE的分子结构是大分子抱团，所以必须要添加稳定助剂使PTFE稳定均匀的分散在乳液中，目前国内的厂家一般使用PFOA或PFOS作为助剂，但是PFOA以及PFOS是一种2B类致癌物质，欧美国家禁止进口含PFOA及PFOS的含氟聚合物，一般国外生产PTFE的公司均不使用此类致癌物质作为助剂。
因此，在消费者选购不粘锅时，需要注意产品是否标明不含PFOA及PFOS，如明确注明，则产品可放心选购。
另外，PTFE可长期而稳定的在260摄氏度下工作，短期耐温可至327度。欧美消费者的烹饪习惯一般以少油、中高温等为主，更注重食材的原汁原味和营养价值，而国内消费者的烹饪习惯一般是以高油、煎炒、爆炒、高温为主，因此同样品质的不粘锅在欧美使用的话寿命较长，而在国内使用的话寿命较短。
总而言之，不粘锅不适宜国内中餐的烹饪方式，不含PFOA及PFOS的不粘锅对人体无害。

首先特氟龙本身无毒，涂层从锅子表面剥离吃进肚子问题不大。但不能空烧，超过260度会不稳定，油炸时一般160-200度。确实，制造时使用的原材料对健康存在争议，现在工艺都比较成熟，出厂时都洗脱干净了，达到标准了。
如果实在不放心，可以选择铁锅、不锈钢锅、钛锅等。刚写了一个关于锅子涂层的回答，使用情况其实都是由材质的特性决定的，我把它们总结了一下，感兴趣可以看看。
不粘锅什么涂层比较安全？

3M knew your non-stick pan was poisoning you in the ’70s
The Intercept has obtained evidence that chemical conglomerate 3M knew about the health dangers of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) since the 1970s. These components were in thousands of everyday products, from water-repelling clothes to Teflon-coated non-stick pans, and they accumulate in your blood causing cancer, damaging your immune system, injuring your liver, spleen, bone marrow, and increasing cholesterol and triglycerides levels putting you at risk of heart attacks. Fun stuff.
These fluorochemicals were the basis for the company’s success, going from a small business called the Minnesota Mining and Manufacturing Company to a $120 billion conglomerate. The company used the discoveries from the Manhattan Project–which used fluorine to distill the uranium for the first atom bomb that dropped over Hiroshima–to develop a magic fluorocarbon fluid called PFOA. Dupont used PFOA to create Teflon, a coating used by hundreds of companies to manufacture miraculous–and toxic–non-stick cookware.
As The Intercept’s Sharon Lerner reports, University of Florida researcher Warren Guy found complex fluorine molecules in his own blood in 1975. He published the results and alerted 3M, asking the company if the molecules may be PFOA or PFOS coming from Teflon or Scotchgard water repellent, as he knew these materials had the same type of molecules. 3M told him they had no clue but the company scientists conducted an investigation and found out that the molecule Guy found in his blood was indeed 3M’s wonder molecule. Then, in a new internal investigation in 1976, company scientists found out that workers at 3M’s Cottage Grove PFOA plant in Minnesota had it in their blood, at concentrations 1,000 times higher than normal. By 1978, Lerner continues, 3M had concluded that PFOA and PFOS “should be regarded as toxic” in another internal report. And in 1979, 3M knew that people all over the United States had this crap in their veins thanks to an analysis of samples from Red Cross blood donors....
