维生素C真的能治疗你的感冒吗?

 　　The jury is still out on whether vitamin C can treat or prevent a cold, but a recent review of the scientific literature suggests that it does have some benefits.

　　虽然维生素C能否治疗或预防感冒依然没有定论，但是最近的一项科学文献综述表明，它确实有一些好处。

　　While supplementing with vitamin C may not prevent colds, according to the studies, there's some evidence that taking vitamin C regularly can help us bounce back from a cold faster.

　　虽然补充维生素C可能不能预防感冒，但是该研究称，有一些证据表明，定期服用维生素C可以帮助我们更快地从感冒中恢复。

　　"Supplemental vitamin C may lessen¹ the duration and symptoms of the common cold because of its immune-enhancing effects," says registered dietitian² Lisa Fischer.

　　注册营养师莉萨·费希尔表示："补充维生素C可以缩短常见感冒的持续时间，减轻感冒的症状，因为它有增强免疫力的效果。"

　　"It's not like if you take vitamin C, it's going cure your cold, but it makes the body more capable of fighting off the virus once you have it."

　　"但这不是说如果你服用了维生素C，它就会治愈你的感冒。不过你服用的维生素C会使身体对抗病毒的能力更强。"

　　In addition to boosting the immune system, Fischer says vitamin C helps repair and regenerate³ tissue, protect against heart disease and certain cancers, aid in iron absorption, decrease LDL cholesterol⁴, and plays a role in building collagen.

　　除了增强免疫系统，费希尔表示，维生素C有助于修复和再生组织、防止心脏病和某些癌症、帮助铁吸收、减少低密度脂蛋白胆固醇，并在构成胶原蛋白中发挥作用。

　　It's also an antioxidant that helps protect cells and DNA⁵ against free radicals⁶ and other harmful agents that can cause damage to cells. To reap the greatest benefits of supplemental vitamin C, Fischer says it's best to make it a daily habit.

　　它也是一种抗氧化剂，有助于保护细胞和DNA免受损害细胞的自由基和其他有害物质的影响。为了获得补充维生素C的最大好处，费希尔称，最好是让它成为一种日常习惯。

　　"Any of the research that supports vitamin C says it's best to take it continuously or consistently, rather than right before you feel like you're getting sick".

　　"任何支持维生素C的研究都表示，最好是持续或连续服用，而不是在感到生病之前才服用"。

　　The best sources of vitamin C may surprise you. "A lot of people assume that vitamin C is found in fruit like oranges, but actually, some of the top sources are vegetables such as bell peppers, broccoli⁷, brussels sprouts⁸, cauliflower, and squash," says Fischer. The best sources from fruit would be papaya, strawberry, pineapple, orange, kiwi, and cantaloupe."

　　维生素C的最佳来源可能会让你惊讶。费希尔称："很多人认为维生素C存在于橙子之类的水果中，但是实际上，一些最主要的来源是蔬菜，如青椒，西兰花、球芽甘蓝、花椰菜和南瓜。水果中最好的来源是番木瓜、草莓、菠萝、橙子、猕猴桃和哈密瓜。"

　　If you're considering supplementation, studies show that consuming between 250 and 1,000 mg of vitamin C a day is considered safe, but more than that could lead to potential gastrointestinal symptoms such as diarrhea and gastritis and other issues.

　　如果你正在考虑补充维生素C，研究表明，每天服用250至1000毫克维生素C被认为是安全的，更多剂量可能导致潜在的胃肠道不适的症状，如腹泻和胃炎等问题。
