糖和果葡糖浆的区别

What's the Difference Between Sugar and High Fructose Corn Syrup?

So, what’s the difference between high fructose corn syrup and sugar
果葡糖浆与糖有什么区别?
Even though it seems like high fructose corn syrup
几乎所有食品和饮品的成分表上
is in every single food and drink wrapped in plastic,
都印有果葡糖浆
you can’t find it for sale alone on the shelf.
但它从不单独出售
It seems a little bit of mystery about this stuff,
果葡糖浆似乎有些神秘
let’s take a look at how different these two sweets are,
让我们来比较下这两种甜味剂
and settle this once and for all.
并一次性理清区别
《化学反应》 由美国化学社出品
High Fructose Corn Syrup made its big time market
果葡糖浆在1970年代的市场上大放异彩
debut in the 1970s due to new taxes on import sugars
这是因为政府向进口糖征收新税
as well as subsidies on corn crops,
同时向玉米种植提供补助金
making it a much cheaper sweetener than regular table sugar.
这使它比常规糖更便宜
Since then, it’s become a pretty standard part of the American diet.
从此 果葡糖浆成为美国饮食的标配之一
HFCS doesn’t come about naturally, but instead
果葡糖浆并非自然产物
through a pretty advanced chemical process.
而是通过一系列极为复杂的化学反应制得
Corn is milled down to produce cornstarch,
先把玉米研磨成玉米淀粉
which is then further broken down into corn syrup
接下来再将其分解成玉米糖浆
– a product that is almost entirely made up of sugar called glucose.
(一种基本由葡萄糖组成的产品)
And while glucose is sweet, it isn’t sweet enough to do the job!
尽管葡萄糖带有甜味 但作为食品添加剂还不够
So in the lab, certain enzymes and acids
所以在实验室里 会用特定的酶和酸
are used to convert some the glucose into fructose, which is significantly sweeter.
将一部分葡萄糖转变为比葡萄糖甜的果糖
So HFCS is a mixture of these two compounds
由此可知果葡糖浆是葡萄糖和果糖
that comes in different variations.
按不同比混合的产品
Glucose and fructose are what are known as monosaccharaides,
葡萄糖和果糖都是单糖
the simplest kinds of sugars,
单糖是最简单的糖
and also the building blocks of the more complex disaccharides.
是复杂二糖的组成单元
Now what’s important to realize is that
要知道常见的蔗糖
common table sugar, or sucrose, is a disaccharide
是由葡萄糖比果糖1:1
made up of equal parts of glucose and fructose.
构成的二糖
HFCS comes in different concentrations for different products,
不同果葡糖浆间是有浓度差异的
but it’s remarkably similar.
但其组成非常相似
The current scientific consensus is that there is
现在的科学界公识认为
almost no nutritional difference between the two.
两者没有营养上的区别
So when it comes to discussing health issues with sweets,
所以当论及吃甜食的健康问题
it’s much less about this
很少关注果葡糖浆与糖
(ONSCREEN: HFCS Vs Sugar) than it is about this
而是关注
(ONSCREEN: huge pile of sugar vs small pile).
大量摄入与少量摄入
When you eat either table sugar or HFCS,
在你摄入糖或果葡糖浆时
both inevitably send glucose and fructose into the blood stream.
两者提供的葡萄糖和果糖都会进入血液系统
Glucose charges our cells up with energy,
葡萄糖可以给细胞供能
while fructose gets involved with cholesterol and
而果糖与胆固醇的形成和
energy-storing glycogen production in the liver.
贮存能源的肝糖原有关
One of the big problems with overconsumption of sweets
其中一个过度摄入糖分的严重问题
is that they start interfering with our metabolism,
是它们会扰乱我们的新陈代谢
and even start playing games with our brain,
有时会捉弄大脑
confusing our sense of hunger and even our feeling of being full.
混淆我们的饿觉和饱腹感
The more sweets we eat,
糖分摄入越多
the more possible physical damage they can do to our bodies.
就越可能对身体造成更多的伤害
Large amounts of Fructose, for example,
例如 大量的果糖
can do a number on your liver,
可以对肝造成严重伤害
and has been directly linked to
并与肥胖 心脏病
obesity, heart disease, and diabetes.
以及糖尿病直接相关
The American Heart Association suggests that women
美国心脏协会建议女士
limit themselves to six teaspoons of added sugar per day,
限制糖的日摄入量在6茶勺以下
while men limit themselves to nine.
男士的日摄入量在9茶勺以内
That’s pretty drastic considering the average
据说美国人的日均摄入量
American consumes around 23 teaspoons a day.
达到非常惊人的约23茶勺
So the big take away with all of this
因此减少疾病的最佳方法
is to put a cap on your sweets.
是限制糖分摄入
It’ll do you good in the long run.
这样对你的身体长期有益
