AZUZ: OK, up next today, how much of your daily diet should be made of carbohydrates? Actually, there`s no one size fits all rule. It depends on your age, your gender, your height, weight, overall health and how much exercise you get.Please visit www.chinavoa.com to get more information.

阿祖兹:今天的下一条新闻,你每天的饮食应该包含多少的碳水化合物?实际上,没有所谓的一刀切的使用原则。因为其取决于你的年龄、性别、身高、体重,整体健康水平以及你锻炼程度。

A dietitian can help you figure out your own daily needs, but there`s a difference in the kind of carbs you get from candy corn and the kind you get from pumpkins.

营养师可以帮助你发现自己每天需要摄入的量,但是这可能与你每日从玉米糖以及南瓜中摄入的碳水化合物有所不同。

DR. SANJAY GUPTA, CNN CHIEF MEDICAL CORRESPONDENT: Food fuels all your activities. You know that. You`re breathing right now, because of the energy you get from food. And yet, most people don`t know very much about what they`re putting into their bodies.

桑基·古普塔 医生,CNN 首席医疗记者:食物会为你所有的活动提供能量,你现在在呼吸,因为你从食物中摄取了能量。但是,现在,大多数人对每天自己的身体在摄入些什么知之甚少。

SUBTITLE: Should you eat carbs?

字幕:我们应该食入碳水化合物吗?

GUPTA: If you`re like most people, the primary source of all of your energy comes from carbohydrates, also known as carbs. They`re one of the macronutrients, along with proteins and fats.

古普塔:如果你像大多数人一样,身体主要的能量来源于碳水化合物。 碳水化合物是主要的营养物质之一,并且其中含有蛋白质和脂肪。

Now, carbs can be healthy. Think about breads, fruits, milk. They can also be unhealthy. Popcorn, soda, cookies.

现在,摄入碳水化合物可以很健康。想想面包、水果以及牛奶。这些碳水化合物也可以变得不健康。例如爆米花、苏打、以及饼干。

But regardless of how they start off, inside your body, any carbs you eat turn into sugar. This process happens really fast with certain types of carbs -- fruits, vegetables, candy, honey. Those are called simple carbohydrates. They provide a quick boost of energy.

但是你的身体怎样摄入成分,你所食入的所有的碳水化合物都会转变成糖类。这个过程在某些化合物的转化中非常的迅速——水果、蔬菜、糖果以及蜂蜜。这些化合物被称为简单的碳水化合物。他们能迅速为机体提供能量。

You get energy over a longer period of time when you eat other types of carbs -- whole grain breads, rice, beans, peas, potatoes. These are called complex carbohydrates. Now, those are going to take longer to digest.

当你吃其他的一些碳水化合物时,经过一长段的时间,可以从中获取能量。这些化合物包括——全麦面包、大米、豆子、豌豆、土豆。这些化合物被称为复杂碳水化合物。现在摄取这些物质需要消耗很长的时间。

If you`re following the Standard American Diet, also known as SAD, you`re consuming up to 65 percent of your calories from carbs and just around 35 percent of your calories from fat. But a diet that`s low in fat and high in carbs, especially the wrong kind of carbs can turn on you.

如果你在收看标准美国饮食这个节目,也被称为SAD,你体内的卡路里有65%来自于碳水化合物,有35%来自于脂肪。但是饮食中脂肪含量过低以及碳水化合物过高,尤其是这两种错误的碳水化合物,可以让你的发生重大的变化。

Here`s what happens: because simple carbs don`t make you feel as full, you end up eating a lot of them. And remember, those carbs turn into sugar, and that sugar flows through your bloodstream. When it does, your body releases a hormone called insulin.

会发生什么样的事情:因为简单的碳水化合物并不会让你有饱的感觉,你就会食入很多这样的化合物。并且记住,这些碳水化合物会转化为糖类,然后这些糖会流进你的血液。这时候,你的身体就会释放一种叫做胰岛素的荷尔蒙。

Insulin is important. It lets your cells know that energy is on the way and it`s up for grabs. But insulin also takes the extra energy from carbs and turns it into fat.

胰岛素是很重要的。它可以让身体的细胞知道有能量来了,并能待价而沽。但是胰岛素也会消耗碳水化合文物的部分能量,将碳水化合物转化为脂肪。

That`s why a sugary drink as well as double cheeseburger can both be bad for your waistline and for your heart.

这就是为什么含糖饮料以及双层芝士汉堡都可以对你的腰围和心脏不好。

这就是糖类饮料以及双层芝士汉堡对腰围以及心脏不好的原因。

Sure, you need carbs. We all do -- but not too many. And remember: not all carbs are the same.

当然啦,你的身体需要碳水化物。我们的身体也需要——但是不要太多。记住:并不是所有的碳水化合物都是一样的。
