有可能过度摄入维生素吗?

Can You Overdose on Vitamins?

如果每天只吃一根胡萝卜
If you eat just one carrot every day,
所摄入的维生素A就足以维持生存
that provides all the vitamin A you need to survive.
但在世界的一部分地区
But in some parts of the world,
这却不是件容易的事
that’s not easy to come by.
约有2.5亿学前儿童存在维生素A缺乏现象
There are an estimated 250 million preschool-aged children who are vitamin A deficient.
他们大多来自非洲和东南亚 例如我所在的印度
Most of them are in Africa and Southeast Asia, like here in India.
其中有25万到50万儿童严重缺乏维生素A
Of those, about 250,000 to 500,000 are severely vitamin A deficient.
缺乏维生素A就会得夜盲症
When that happens, they get night blindness,
天黑后 他们就丧失了视力
which means as the Sun goes down they lose their ability to see.
现在如果你了解了实际情况
Now if you catch the condition at that point, and
给孩子一些高剂量维生素A补充剂
give a child just a few high dose vitamin A supplements,
他们的视力就会在24到48小时之内恢复
their sight can be restored within 24 to 48 hours.
听起来像是什么神奇疗法
It’s like a miracle cure.
但如果你不做
But if you don’t,
情况会继续恶化 直到彻底失明
well the condition can continue to worsen until they’re completely blind.
这些失明的孩子中
And of those children who are completely blind,
大约一半会在12个月之内死亡
roughly half die in the following 12 months.
这是我参与制作了
These are all things I learned
一部长达90分钟的新纪录片后了解到的所有信息
while working on a new feature length 90-minute documentary
片名《维生素狂热》讲述了关于维生素的一切真相与谎言
called”Vitamania”, all about these sense and nonsense of vitamins.
我不仅是纪录片的主持人
And I am not only the presenter of this documentary,
也是执行制作人之一
I’m also one of the co-executive producers.
现在你就能看到这部纪录片
And you can watch this documentary right now.
它已在网络上线 世界各地都可以看
It is live, on the web, for everywhere in the world
除了法国和德国 因为要在电视上播出
except France and Germany because it’s coming to your TVs.
我会把《维生素狂热》的链接
But I will put a link to it, Vitamania the Movie”,
放在简介里和视频右侧
in the description and right here.
我想给你们看看预告片
And I want to show you a trailer for this film,
你们就会明白它是什么样的
so you get a sense of what it looks like,
知道内容是什么
what it’s all about.
做这部纪录片 我花了两年半时间
It’s something I’ve been working on for two and a half years,
所以我为之骄傲
so I’m really proud of it,
我想让你们去看看
and I just want you to go and check it out.
接下来就是一个预告片
So here is the trailer.
1913年 南极探险家Douglas Mawson
In 1913, Antarctic explorers Douglas Mawson and
和Xavier Mertz正挣扎求生
Xavier Mertz were fighting for their lives.
随着食物消耗殆尽 他们面临着一个难题:
With most of their food gone, they faced a stark choice:
要想生存 就要把他们的狗吃掉
Eat their dogs, or die.
[音乐]
[MUSIC]
无奈吃掉狗之后
After reluctantly eating their dogs,
众人就生病了 发起了高烧
the men fell ill, burning with fever.
不出几天 Mertz就死了
Within days, Mertz was dead.
Mawson在绝境中活了下来 成功回到了营地
Mawson, against the odds, made it back to camp.
是什么神秘疾病杀死了Mertz
So what was the mystery illness that killed Mertz,
而且差点让Mawson丢了性命呢?
and nearly cost Mawson his life?
他们吃狗的时候
Well, when they ate their dogs,
不仅吃掉了狗肉和脂肪
they weren’t just eating canine flesh and fat.
也吃掉了狗的肝脏
They also ate the dog’s livers,
其中含有大量维生素A
which contain high levels of vitamin A.
所以基本上说 他们是维生素A摄入过量
So basically, they overdosed.
这种情况被称为维生素A过多症
It’s a condition known as Hypervitaminosis A.
维生素A过多症罕见却致命
Hypervitaminosis A is rare but deadly,
现在我们知道它是由
and today we know it can be caused by
过度使用高剂量维生素A补充剂引起的
overuse of high-dose vitamin A supplements –
和拯救孩子视力的补充剂是同一种
the same kind of supplements that can save a child’s sight.
这种复杂的力量正是
This power and complexity
维生素精彩故事的核心
lies at the heart of the great vitamin story.
[音乐]
[MUSIC]
我要踏上去往世界各地的精彩旅程
I’m embarking on an epic world-spanning investigation
去探寻维生素的科学与历史
of vitamin science and history.
“啊!”
“Aargh!”
“这条鱼真大!”
“That is one big fish!”
我想了解维生素的发现历程
I want to know how we discovered them,
“你确定这个安全?”
“ You sure this is safe? ”
维生素究竟是什么
what they actually are,
“13种维生素可被分为两类”
“ The 13 vitamins can be divided into two teams. ”
我们研制出维生素的过程
how we learnt to build them,
“今晚 Walgreens和Target两家药店在全国下架这些产品”
“Tonight, Walgreens and Target have pulled the products nationwide-”
以及维生素有多么安全
and how safe they are.
“所有维生素 所有营养素过量摄入都是有毒的”
“ All vitamins – all nutrients – they are toxic in high amounts.”
“我们应该认真对待
“ We’ve got to start taking these seriously,
摄入体内的任何化学物质”
as we should with every chemical we put into our bodies. ”
我是一名科学家
I’m a scientist.
也是一位父亲
I’m also a father,
我想知道
and I want to know,
怎样做才是对我的儿子最好
how do I do the best for my son.
未来他是否有可能将维生素片带去火星?
And one day, might he be taking vitamin pills to Mars?
[火箭发射]
[ROCKET LAUNCHING]
在世界各地
Across the world,
一些专家称维生素可救人性命
some experts claim that taking vitamins can be lifesavers,
而其他专家认为服用维生素浪费时间 甚至会有危险
whereas others argue that it’s just a waste of time or even dangerous.
那我们怎么知道是否应该服用维生素呢?
So how are we supposed to know whether to take them or not?
维生素狂热维生素的真相与谣言
