A |     为什么能炒作起来？是很多人完全不了解苯甲酸钠（很多人看到苯这个词就自动脑补了），其实经常与它同时出场的还有山梨酸钾，很多食品、饮料中都可以看到它们的存在，因为这是两种最为常用的防腐剂了，可以抑制霉菌，酵母菌和好氧性细菌的活性，还能防止肉毒杆菌、葡萄球菌、沙门氏菌等有害微生物的生长和繁殖。

B | 它们的优点很多人不关注，然而在短视频平台传播的主要是说它们的缺点，特别是苯甲酸钠的致癌性，甚至还有人引用国外的研究，证明每天给小鼠使用0.4克的苯甲酸钠一个月后就可能导致病变的情况，这让不少人闻之色变。    DUBAI, United Arab Emirates -- While revealing new details about one of the most famed CIA operations of all times — the spiriting out of six American diplomats who escaped the 1979 U.S. Embassy seizure in Iran — the intelligence agency for the first time has acknowledged something else as well.The CIA now officially describes the 1953 coup it backed in Iran that overthrew its prime minister and cemented the rule of Shah Mohammad Reza Pahlavi as undemocratic.Other American officials have made similar remarks in the past, but the CIA's acknowledgment in a podcast about the agency's history comes as much of its official history of the coup remains classified 70 years after the putsch. That complicates the public's understanding of an event that still resonates, as tensions remain high between Tehran and Washington over the Islamic Republic's rapidly advancing nuclear program, its aiding of militia groups across the Mideast and as it cracks down on dissent. The “CIA’s leadership is committed to being as open with the public as possible," the agency said in a statement responding to questions from The Associated Press. "The agency’s podcast is part of that effort — and we knew that if we wanted to tell this incredible story, it was important to be transparent about the historical context surrounding these events, and CIA’s role in it.”In response to questions from the AP, Iran's mission to the United Nations described the 1953 coup as marking “the inception of relentless American meddling in Iran’s internal affairs” and dismissed the U.S. acknowledgments.“The U.S. admission never translated into compensatory action or a genuine commitment to refrain from future interference, nor did it change its subversive policy towards the Islamic Republic of Iran,” the mission said in a statement. The CIA's podcast, called “The Langley Files” as its headquarters is based in Langley, Virginia, focused two recent episodes on the story of the six American diplomats' escape. While hiding at the home of the Canadian ambassador to Iran, a two-man CIA team entered Tehran and helped them fly out of the country while pretending to be members of a crew scouting for a made-up science fiction film.The caper, retold in the 2012 Academy Award-winning film “Argo” directed by and starring Ben Affleck, offered a dramatized version of the operation, with Affleck playing the late CIA officer Antonio “Tony” Mendez. The podcast for the first time identified the second CIA officer who accompanied Mendez, naming him as agency linguist and exfiltration specialist Ed Johnson. He previously only had been known publicly by the pseudonym “Julio.”“Working with the six — these are rookies," Johnson recounts in an interview aired by the podcast. "They were people who were not trained to lie to authorities. They weren’t trained to be clandestine, elusive.” But in the podcast, another brief exchange focuses on the 1953 coup.In it, CIA spokesman and podcast host Walter Trosin cites the claims of agency historians that the majority of the CIA’s clandestine activities in its history “bolstered” popularly elected governments.“We should acknowledge, though, that this is, therefore, a really significant exception to that rule,” Trosin says of the 1953 coup.CIA historian Brent Geary, appearing on the podcast, agrees.“This is one of the exceptions to that," Geary says.Seven decades later, the 1953 coup remains as hotly debated as ever by Iran, its theocratic government, historians and others. Iran's hard-line state television spent hours discussing the coup that toppled Prime Minister Mohammad Mosaddegh on its anniversary in June. In their telling, a straight line leads from the coup to the 1979 Islamic Revolution that ultimately toppled the fatally ill shah. It still fuels the anti-Americanism that colors decisions made by the theocracy, whether in arming Russia in its war on Ukraine or alleging without evidence that Washington fomented the recent nationwide mass protests targeting it. From the U.S. side, the CIA's hand in the coup quickly was revealed as a success of Cold War espionage, though historians in recent years have debated just how much influence the agency's actions had. It also led the CIA into a series of further coups in other countries, including Guatemala, where American clandestine action in 1954 installed a military dictator and sparked a 40-year civil war that likely killed some 245,000 people.That's led to an American political reappraisal of the 1953 CIA action in Iran. Then-Secretary of State Madeleine Albright acknowledged the U.S.' "significant role" in the coup in 2000. President Barack Obama, speaking in Cairo in 2009, described the CIA's work as leading to the “overthrow of a democratically elected Iranian government.” But largely absent from the discussion was the CIA itself. After years of conflicting versions of the coup both in public and classified papers, a member of the CIA's own in-house team of historians wrote a reappraisal of the operation in a 1998 paper titled “Zendebad, Shah!” in Farsi — or “Long Live the Shah!”But despite a series of American historical documents being made public, including a major tranche of State Department papers in 2017, large portions of that CIA reappraisal remain heavily redacted despite attempts to legally pry them loose by the George Washington University-based National Security Archive. That's even after pledges by former agency directors Robert Gates and James Woolsey Jr. in the 1990s to release documents from that coup and others engineered by the agency. Further complicating any historical reckoning is the CIA's own admission that many files related to the 1953 coup likely had been destroyed in the 1960s.“It’s wrong to suggest that the coup operation itself has been fully declassified. Far from it," said Malcolm Byrne of the National Security Archive. "Important parts of the record are still being withheld, which only contributes to public confusion and encourages myth-making about the U.S. role long after the fact.”。事实如何呢？学过化工的都直到一句话，抛开剂量谈毒性就是耍流氓，先不说小鼠试验得出的结论是否适用于人类，退一步讲就算是研究结论成立，那人类每天食用多少才可能导致癌变？这个事已经有微博大V@蘸盐给算过了，按照国家标准、一家三口正常做饭及小鼠数据来换算，如果要达到小鼠病变的标准，正常人每天要吃400克苯甲酸钠，相当于每天喝400公斤酱油，添加剂超标4万倍才行。这样算起来，按照国外研究的结论，人类不用等苯甲酸钠可能的癌变，每天喝400公斤酱油就出问题了，哪怕是光喝水也会导致水中毒的。总之，面对网上的各种耸人听闻的食品安全视频，特别是现在短视频上的各种言论，大家还是长点心为好，现代食品工业带来的科技进步让所有人都能吃上便宜、安全的美食，小小的苯甲酸钠也是功不可没，没必要谈之色变，更不要妖魔化合法合规的食品添加剂，包括三花淡奶。至于没有添加剂的食品，很多人对这种想象中的天然食品往往有脑补的加成，事实上稍微经历过北方农村自酿酱油、大酱的网友可能还有点印象，自酿酱油是否安全卫生不说，这种没有添加剂的酱油是保存不了多久的，很多人是没体验过酱油、黄酱生虫（至于是什么虫，北方网友可能都懂）的恶心情况吧。
