FDA必須對(duì)食品中添加的數(shù)千種化學(xué)物質(zhì)進(jìn)行更多監(jiān)管

Pretend you're pregnant.

假如你懷孕了。

You're careful about every morsel you put into your mouth, exquisitely conscious about the potential impact on your growing baby's development.

你小心翼翼地吃進(jìn)嘴里的每一口食物，非常清楚地意識(shí)到它對(duì)寶寶成長(zhǎng)發(fā)育的潛在影響。

But there is a catch: No matter how careful you may be, the food you eat and the beverages you drink likely contain one or more of some 10,000 chemicals allowed to be added to foods -- some of which are known endocrine (hormone) disruptors linked to developmental, cognitive and other health problems in babies and adults.

但有一個(gè)問(wèn)題：無(wú)論你多么小心，你吃的食物和喝的飲料都可能含有允許添加到食物中的大約10000種化學(xué)物質(zhì)中的一種或多種——其中一些是已知的內(nèi)分泌(激素)干擾因子，與嬰兒和成人的發(fā)育、認(rèn)知和其他健康問(wèn)題有關(guān)。

Yet the agency charged with protecting our food from unsafe chemicals -- the US Food and Drug Administration -- hasn't been doing the job Congress intended when it passed the 1958 Food Additives Amendment, according to a citizen's petition filed Wednesday and provided exclusively to CNN in advance.

然而，根據(jù)周三提交給CNN的一份公民請(qǐng)?jiān)笗?，?fù)責(zé)保護(hù)我們的食品不受不安全化學(xué)物質(zhì)侵害的機(jī)構(gòu)——美國(guó)食品和藥物管理局——并沒(méi)有履行國(guó)會(huì)在通過(guò)1958年食品添加劑修正案時(shí)所打算做的工作。

"The FDA never considers the overall effect of these 10,000 chemicals on people's health, which is what Congress was after," said Tom Neltner, the chemicals policy director for the Environmental Defense Fund, a key signatory of the petition.

“美國(guó)食品和藥物管理局從來(lái)沒(méi)有考慮過(guò)這10000種化學(xué)品對(duì)人們健康的總體影響，而這正是國(guó)會(huì)想要的，”湯姆·內(nèi)爾納說(shuō)，他是環(huán)境保護(hù)基金的化學(xué)品政策主管，也是請(qǐng)?jiān)笗年P(guān)鍵簽到人。

"And it's not simply one plus one equals two. We know that synthetic chemicals that harm hormones have what we call additive or synergistic effects," said Dr. Leonardo Trasande, co-author of the American Academy of Pediatrics' policy statement on the potential harms of food additives and packaging, which is part of the citizen's petition.

“一加一不等于二。美國(guó)兒科學(xué)會(huì)關(guān)于食品添加劑和包裝潛在危害的政策聲明的合著者萊昂納多·特拉森博士說(shuō):“我們知道，有害激素的合成化學(xué)物質(zhì)具有我們所說(shuō)的添加劑或協(xié)同效應(yīng)。”這也是公民請(qǐng)?jiān)傅囊徊糠帧?/p>

Consider the cumulative effect

考慮累積效應(yīng)

Scientists used to think that it was a baby's thyroid hormone level that was important to brain development. Studies have now shown that a shift in an expecting mother's thyroid hormone, "even if it's so subtle it doesn't show up on a clinical test," can have consequences to a child's future development, Trasande said.

科學(xué)家們過(guò)去認(rèn)為，嬰兒的甲狀腺激素水平對(duì)大腦發(fā)育至關(guān)重要。特拉森說(shuō)，現(xiàn)在的研究已經(jīng)表明，孕婦甲狀腺激素的變化，“即使在臨床測(cè)試中沒(méi)有顯示出來(lái)，”也會(huì)對(duì)孩子未來(lái)的發(fā)育產(chǎn)生影響。

The plastic wrap can contain chlorine, the nonstick cookware is made with perfluoroalkyl and polyfluoroalkyl substances (PFAS), and the vegetables and drinking water may contain nitrates from fertilizers, which often leach into ground water, especially in agricultural areas.

保鮮膜可能含有氯，不粘鍋是由全氟烷基和多氟烷基物質(zhì)(PFAS)制成的，蔬菜和飲用水可能含有肥料中的硝酸鹽，這些硝酸鹽經(jīng)常滲入地下水，特別是在農(nóng)業(yè)地區(qū)。

All three of those chemicals are known endocrine disrupters. A review of the last five years of research by Trasande found an "explosion of evidence" about the negative impact on our health of such chemicals in agricultural pesticides and plastic or other containers used in manufacturing that touch our food.

這三種化學(xué)物質(zhì)都是已知的內(nèi)分泌干擾物。特拉森對(duì)過(guò)去五年的研究進(jìn)行了回顧，發(fā)現(xiàn)“大量證據(jù)”表明，農(nóng)業(yè)殺蟲劑、塑料或其他用于生產(chǎn)食品的容器中的化學(xué)物質(zhì)會(huì)對(duì)我們的健康造成負(fù)面影響。

Any negative impact of food additives will be much worse for children of any age, said Dr. Margaret Cuomo, author of "A World Without Cancer," a book that explores environmental impacts on cancer risk.

《沒(méi)有癌癥的世界》一書的作者瑪格麗特·科莫博士說(shuō)，食品添加劑的任何負(fù)面影響對(duì)任何年齡的兒童都將嚴(yán)重得多。這本書探討了環(huán)境對(duì)癌癥風(fēng)險(xiǎn)的影響。

"Children are always the most vulnerable especially when it comes to the endocrine disrupters," Cuomo said, "because their endocrine, neurological and reproductive systems are just developing. And so these chemicals have a much higher impact on their little bodies compared to adults."

科莫說(shuō):“兒童總是最脆弱的，特別是當(dāng)涉及到內(nèi)分泌干擾物時(shí)，因?yàn)樗麄兊膬?nèi)分泌腺、神經(jīng)系統(tǒng)和生殖系統(tǒng)才剛剛發(fā)育。因此，與成年人相比，這些化學(xué)物質(zhì)對(duì)他們幼小的身體的影響要大得多。”

It's the FDA's responsibility to step up and remove the responsibility of avoiding such dangers from consumers, said Dr. Aparna Bole, chair of the AAP's Council on Environmental Health, who worked on the petition.

美國(guó)兒科學(xué)會(huì)環(huán)境健康委員會(huì)主席、參與起草請(qǐng)?jiān)笗陌⑴良{·博爾博士說(shuō)，F(xiàn)DA有責(zé)任站出來(lái)，免除消費(fèi)者避免此類危險(xiǎn)的責(zé)任。

Regulate the class of chemicals

監(jiān)管化學(xué)品類別

The way the FDA approaches its regulatory job contributes to the problem, experts say.

專家說(shuō)，F(xiàn)DA處理其監(jiān)管工作的方式是造成這一問(wèn)題的原因之一。

Take PFAS chemicals, which have been linked to an increased risk of cancer, asthma and thyroid disease, as well as liver damage and decreased fertility. Called "forever" chemicals, because they do not degrade in the environment, PFAS are so widespread that levels have been detected in the blood of 97% of Americans, according to a 2015 report by the US Centers for Disease Control and Prevention.

以PFAS化學(xué)物質(zhì)為例，它會(huì)增加患癌癥、哮喘和甲狀腺疾病的風(fēng)險(xiǎn)，還會(huì)損害肝臟和降低生育能力。被稱為“永久”的化學(xué)物質(zhì)，因?yàn)樗鼈冊(cè)诃h(huán)境中不會(huì)降解。根據(jù)美國(guó)疾病控制和預(yù)防中心2015年的一份報(bào)告，PFAS在美國(guó)非常普遍，97%的美國(guó)人的血液中都檢測(cè)到了這種物質(zhì)。
