高果糖玉米糖浆:营养“黑魔王”

High-Fructose Corn Syrup: The "Dark Lord" of Nutrition

如今 人们似乎乐于讨厌美味的东西
People do seem to love to hate stuffthat tastes good these days.
有时 当然理由充分
Sometimes there is a good reason for it, of course,
但有时 感觉我们只是和自己过不去
but sometimes I feel like we’re just giving ourselves a hard time.
比如 小时候 我进过的每间厨房
When I was a kid, for example, every kitchen I ever went into
都堆满脱脂食物
was full of fat free stuff,
因为每位妈妈在早间节目中都听说过
because everybody’s mom had heard on some morning show that
如果吃了带脂肪的食物 就会变成
if you eat anything with fat in it, you’re gonna turn into
一个鼓鼓囊囊的海象形沙发垫
an overstuffed walrus shaped couch cushion,
所以我们总喜欢吃涂满人造奶油的百吉饼
so we always date things like bagels slathered in margarine.
有时 我放学回家 吃掉一整盒脱脂饼干
And sometimes I’d come home from school, eat a whole box of fat free cookies.
它们不含脂肪
Because they’re fat free,
所以吃多少都没关系 什么?
it doesn’t matter how many you eat. What?
我们为什么要这么做?
Why do we even do this?
饼干居然能脱脂 怎么做到的?
How do you even make a cookie fat free?
现在 人们又开始吃含脂食物
So, now people are eating fatty thingsagain
感谢上帝
and I mean thank God.
感觉真好
now I’m good.
现在 高果糖玉米糖浆取代脂肪
At the moment though instead of fat, the new Dark Lord of nutrition is
成为新的营养“黑魔王”
high fructose corn syrup
我看过 这根玉米热狗不含高果糖玉米糖浆
and I checked there is no high fructose corn syrup in this corn dog.
人们厌恶它 强烈反对把它加在食品中
People despise it. We’ve gotten so up in arms that food companies
食品公司只好将它从原料中剔除
are now kicking it out of their products
并用全天然糖取代它
and replacing it with all-natural sugar.
许多人把它叫做HFCS
To here, a lot of people tell it HFCS, as people have started calling it
听上去化工感更强
to make it sound more chemically,
人们视它为爱 美好 纯洁的敌人
is the enemy of love and all things good and pure
是导致肥胖流行的唯一原因
and the sole cause of the obesity epidemic.
说到肥胖症 我做过一期专题
Speaking of the obesity epidemic, I did a whole show on that.
你应该看看
you should watch it.
正如网上说的 “仇恨者会继续黑别人”
Anyway you know as they say on the internet “Haters gonna hate” .
这是网络用语 还是城市俚语?
They say that on the internet or is that is that an urban slang thing?
但仇恨者是否也有一定道理?
but do the haters have a valid point and we’ve been doing
我们对此做了研究 事实上 结论不确定
research on this and we’re not quite sure actually.
HFCS真是一件奇妙的创造发明
So, high fructose corn syrup is kind of a wonderful creation really.
它非常便宜
It’s extremely inexpensive,
易运输 易与其它物质混合
easy to transport, easy to mix intothings.
大大降低了食物价格
It made food a lot cheaper,
在美国 摄入的每份卡路里都因它而便宜
certainly made every calorie that we eat in America cheaper.
哦 这当然也要归功于给玉米种植者的
Oh, this is of course all with the help of 40 billion
400亿美元补贴
dollars of subsidies to corn farmers.
由于上述种种原因
for all these reasons and more,
上世纪70年代起 HFCS使用量飙升
the use of high fructose corn syrup has been skyrocketing since the 1970s
现在 如果你吃着某种甜食
and now if you’re eating something sweet, there’s about
其甜味来自HFCS的几率约为50%
a 50% chance that that sweetness is coming from high fructose corn syrup.
以上是事情表象
That said on the surface of things.
蔗糖 也叫甘蔗糖 全天然糖 食糖
Sucrose, which we know as cane sugar or all-natural sugar or table sugar,
它和HFCS本质上是一样的
and high fructose corn syrup are basically the same thing.
它们都是植物性甜味剂
They’re both plant-based sweeteners
在分子水平上 它们非常相似
and on a molecular level, they’re pretty similar.
蔗糖和HFCS都由葡萄糖和果糖组成
Both sugar and high fructose corn syrup are made out of glucose and fructose.
化学上蔗糖是葡萄糖和果糖分子的结合物
Chemically, sucrose is just a glucose molecule and a fructose molecule bonded together,
而HFCS是葡萄糖和果糖分子的混合物
while high fructose corn syrup is just a mixture of glucose and fructose molecules,
两种分子没结合在一起
without them being bound together.
但分子归分子 口感上 果糖甜多了
But molecule for molecule, fructose actually tastes a lot sweeter to us
需要说明一点 果糖之所以叫果糖
and I should point out that fructose is called fructose
是因为我们总在水果中找到它
because it’s the kind of sugar that we generally find in fruits.
如果HFCS本质就是葡萄糖和果糖
So, if a high fructose corn syrup is basically just glucose
葡萄糖是宇宙中最常见的糖
which is the most common sugar in the universe,
果糖是在苹果汁中都能找到的糖
and fructose which is the kind of stuff that you find in apple juice,
那么 HFCS怎么会有害?
how could it be that bad for you?
我们为何如此多疑?
What makes us so suspicious?
好了 这有一张图
Well, we have this graph right here.
没错 图上显示美国的肥胖率大幅上升
Yeah, that’s the obesity rate in America going through the roof,
与此同时 杂货店的每件产品中
right about the same time, that every single product in the grocery store
HFCS含量也在增加
started getting enhanced with high fructose corn syrup.
这是种相关性 不是因果关系
And that is a correlation not acausation.
但这是值得研究的相关性
But it is a correlation worth investigating.
比如 最近对老鼠的一些研究表明
For example, some recent studies on rats are beginning to show that
喂HFCS的老鼠比只吃蔗糖的老鼠胖许多
high fructose corn syrup makes the rats way fatter than if they just ate table sugar.
HFCS还提高了老鼠血液的脂肪含量
and it’s also raising levels of fat content in their blood.
但也有许多其他研究表明
But there have been a lot of other studies that have shown
无论吃蔗糖还是HFCS 都无显著差异
no significant change depending on whether you’re eating table sugar or high fructose corn syrup.
但有一点是肯定的
One thing however is certain
我们现在吃的许多东西都有HFCS
that high-fructose corn syrup is a lot of what we’re eating these days.
它让甜食更便宜
It’s making sweet foods much less expensive,
这样消费成本就降低了
so the barrier to consuming them is lower
来杯冰爽的可口可乐真是畅快
and it is very rewarding to have an ice-cold coca-cola
所以这问题涉及经济学 生化和脑化学
so there’s a combination of economics, biochemistry, brain chemistry,
总之 人们吃各种各样的糖
and in general, people eating sugar of all kinds
这恐怕不是好事
which probably isn’t very good for us.
对了 谁要这个?我买的 但我不想要了
And in the mean times, anybody want these? because I bought them and I don’t want them.
关于HFCS 想了解更多
For more information on high fructose corn syrup,
它意味什么?不意味什么?
what it means? what it doesn’t mean?
请看详情介绍 那有更多的信息
Check out the description, we’ve got some more information in there.
如果你有感兴趣的主题
If you’ve got topics and
