痘痘脸？食物和痤疮的真相 A healthful diet rich in leafy vegetables, beneficial fatty acids, and protein is certainly crucial if you want to create and maintain a gorgeous complexion. After all, a healthy, well-balanced inside often yields a beautiful outside. But if you struggle with chronic acne—either adult breakouts or the time-honored trials of teenage skin—the unsatisfying truth is that despite numerous studies, the jury is technically still out as to whether diet can trigger chronic breakouts. Acne is largely caused by hormones, yet cautionary tales about how certain foods yield breakouts stubbornly persist. Read on to find out which “acne-causing foods” can be dismissed as the stuff of myth and which are true acne culprits.
如果你想拥有动人、富含蛋白胶原的完美皮肤，一个有益于健康的饮食——大量的蔬菜和有益脂肪酸是必备的。因为身体内部的健康和营养均衡，会投射到身体表面。无论你长期和痤疮进行斗争——成年型爆发痤疮或是从少年时期一直没有痊愈，虽然有很多研究，但是却无法表明饮食是否会导致慢性痤疮爆发。痤疮主要是由荷尔蒙产生，一些人却坚持着某些食物会导致痤疮的爆发。继续阅读这篇文章，你将会找到食物和痤疮的关系—— 哪些是真凶，哪些则是被冤枉的。
Does Greasy, Fried Food Cause Acne? Probably Not.
油腻的、油炸的食品会引起痤疮吗？也许不会。
Cheesy pizza, oily potato chips, french fries, and juicy cheeseburgers won’t give you pimples. This myth began because people once thought that fatty foods must cause acne since they contain oil, and sebaceous oil causes acne. The problem with that logic is that the oil in food has absolutely no relationship to the sebum on your skin, and the only way that pizza could directly cause acne is if you rubbed it on your face.
起司披萨、炸薯条、炸土豆片、多汁的芝士汉堡等，不会让你起粉刺。这个说法的由来是由于人们认为脂肪过多的食物一定会导致痤疮，因为这些食物中包含油，而这些脂肪油则会导致痤疮。这样的思考逻辑会推理出会食物中的油，和皮肤分泌的油脂毫无关系，而吃披萨可以产生痤疮的唯一方式则是把它往你的脸上涂抹。 
Do Carbohydrates Cause Acne? Maybe. 糖类会产生痤疮吗？也许吧。 Some studies have suggested that simple carbohydrates contribute to high levels of insulin in the blood, which can disrupt normal hormonal function and lead to imbalances that, in turn, lead to acne. Speaking at the American Academy of Dermatology’s summer symposium in 2011, Dr. Alan Shalita of the SUNY Downstate Medical Center in New York said, “I would encourage patients with acne to moderate the amount of carbs that they eat.” Eating a diet low in carbs can help keep blood glucose and insulin production in check. 一些研究表明，单一碳水化合物导致血液中胰岛素的升高，这会破坏正常荷尔蒙功能的平衡，反过来导致痤疮的产生。在2011年美国皮肤学会的夏季研讨会中，来自美国纽约州立大学州南部医学中心的艾伦沙利塔博士说道，“我鼓励痤疮病人减少碳水化合物的摄入”。食用低碳水化合物的食物，可以控制血糖和胰岛素。undefined Does Chocolate Cause Acne? Probably Not. 巧克力会导致痤疮？也许不会。 Diana McShane, a dermatologist at Duke University, says, “Chocolate has been implicated in the role of acne for decades without any convincing data to support or refute this theory.” Several studies have found no relationship between chocolate and acne, but somehow none have been conclusive enough to officially close the book, so the misconception continues. Still, most medical professionals agree that it’s an old wives’ tale. 杜克大学的皮肤科专家戴安娜麦莎妮说，“巧克力一直被卷入到痤疮的问题中，然而却没有强有力的证据去支持或反驳这个理论。”一些研究证明巧克力和痤疮之间没有关系，但是却一直没有一个决定性的研究去结束这一争论，错误的观点也持续了下去。然而，大多数医学专家仍然同意这是一个无稽之谈。
Does Dairy Cause Acne? Maybe. 乳制品会导致痤疮吗？也许。 The longitudinal Nurse’s Health Study, conducted at Harvard University, discovered that women who drank more milk as teenagers tended to have more and worse acne than those who consumed little dairy. Other studies of children and teenagers have replicated these findings. Doctors hypothesize that the main problem is the hormones present in most milk products, which interfere with normal hormonal function. Another possibility is that milk sugar increases insulin levels in the same way that carbs do. In fact, some doctors even think that the reason chocolate gets such a bad rap with regard to acne is really more about the milk and sugar that candy bars contain and not the cocoa itself. 哈佛大学所研究的一项关于护士身体健康的纵向调查表明，相对于饮用少量乳制品的人来说，女性在青少年期间如果饮用更多乳制品，将会产生更多或更糟的痤疮。其他关于孩子和青少年的调查也证实了这些发现。医生假设主要的问题在于牛奶中的荷尔蒙含量，会打乱正常荷尔蒙的功能。另一个可能性是，在某种程度上来说，和碳水化合物一样，乳糖提高了胰岛素的标准。事实上，一些医生甚至认为巧克力背负痤疮的罪名，是因为牛奶和糖是糖果中所含的，而并不是可可本身。 |
