Carbohydrates are an important source of energy. But if you eat too many carbs, it can lead to health problems likeobesity. That issue is the focus of this week's Weight of the Nation Conference.
A new report was released at the meeting. It estimates that by the year 2030, 42 percent of the U.S. population will be obese. That's 30 million more Americans than right now. The medical costsassociatedwith that increase would total up to nearly $550 billion.
Soledad O'Brien talked with CNN's Dr. Sanjay Gupta about some of the reasons behind this issue.
Sanjay, before we get to the numbers, explain to me why are we getting that fat so quickly?
Well, you know, if there's any good news in this -- and I'm not sure there's a lot, Soledad, is that the numbers are actually originally expected to be worse. They said 51 percent at one time they predicted the nation would be obese. This is adults by the year 2030. So 42 percent is still nothing great, obviously. Eleven percent they think will be severely obese.
Look, Soledad, you'll hear a lot of the same sort of things that you've heard for some time. I mean, you've been covering this for a long time now, as have I. Too many fast food restaurants. It's too inexpensive to get unhealthy calories. There's not enough park s, too many roads, all those things, those keep coming up.
And despite the fact that those mess ages have been heard and understood, the problem just keeps getting worse. I think, you know, there's a lot to it at the individual level I think simple things can help, you know, simply eating more food in the morning, they find. Getti ng up and walking around.
But I think there's a larger problem, and that is that it's not just how much we eat but what we're eating as well. You know, sugar, for example, I'll just give you a quick example, probably behaves differently in the body than just about any other calorie. It makes you gain weight, but it also creates these lipids that are really bad for the heart, raisesinsulinlevels and makes you store even more fat.
So for a long time, we thought health foods, for example, were low- fat, high-sugar foods. And as we became that country that ate that kind of diet, the problem just became even worse.
All right. Now you heard Dr. Gupta talk about some ways that individuals can work to prevent obesity. At the Weight of the Nation Conference, experts had some other ideas, some othersolution s.
Some of those in clude a shirt in farming policies so there's more focus on fruits and vegetables. There's also a suggestion for a possible tax on sugary drinks, though there's somecontroversyassociated with that. Another idea is to start the fight against obesity at school. For instance, requiring schools to provide an hour of physical education or activity every day.
Now picture this scenario: your team is moving through a building. The possibility of danger all around. You need to comple te your objective to get everyone out safely. Sounds like a video game. It's also a situation that firefighters routinely find themselves in. Brooke Baldwin explains how new technology can help them.
碳水化合物是一种重要的能源。

但如果你吃太多的碳水化合物,可能会导致如肥胖等的健康问题。

这个问题是本周的国家会议谈论的焦点。

一份新的报告在会议上公布。

预计到2030年,美国42%的人口将存在肥胖问题。

将超出美国现在人口3000万。

与此相关的医疗成本增加将达近5500亿美元。

索利达德·奥布莱恩与CNN的桑杰·古普塔谈论一些关于这个问题背后的原因。

桑杰,在我们开始讨论这些数字之前,向我解释下为什么我们会胖得这么快呢?
嗯,你知道,如果有什么好消息的话,在这里,我不是确定有很多,这些数字实际上比原本预期的要更糟。

他们曾预测这个国家51%的人口患上肥胖。

这是到2030年的成年人数量。

所以42%仍然是伟大的,很明显。

他们认为11%的人将严重肥胖。

看,你会听到很多同样的东西。

我的意思是,你已经了解这个很久了,因为有太多的快餐店。

太不便宜反而得到不健康的卡路里。

没有足够的公园,太多的道路,所有这些东西,这些不断出现。

尽管事实上这些信息被倾听并理解,但问题只会越来越糟。

我想,你知道, 我认为简单的东西可以帮助许多需要它在个人水平上,你知道, 他们发现只是在早上吃更多的食物并起床走动。

但是我认为这是一个更大的问题,那就是,它不仅仅是吃多少,但我们也吃。

你知道,糖,例如,我将给你举一个很简单的例子, 任何其他热量可能会在身体有不同的作用。

它让你增加体重,但它同时创造了这些脂质,这真的对心脏不利,提高胰岛素水平,让你储存更多脂肪。

因此很长一段时间里,我们认为健康的食物,例如低脂肪，高糖的食物。

而当我们将这些端上这个国家人民的餐桌上并开始这种饮食,问题开始变得更糟。

好吧。

现在你听到古普塔博士谈论的某些方面,个人可以通过努力避免肥胖。

在这次会议上,
专家们有一些其他的想法,一些其他的解决方案。

其中包括农业政策,更集中在水果和蔬菜上。

还有一种建议是可能对含糖饮料征税,尽管有一些与之关联的争议存在。

另一种想法是开始在学校内对抗肥胖。

例如,要求学校提供一小时的体育课和每天的活动等等。

现在想象这样的情景:你的团队正在穿过一个建筑。

周围都可能发生的危险。

你必须完成你的目标,让每个人都安全脱险。

听起来像一个视频游戏。

这也是一个消防队员经常发现自己在这种情境之中的情境。

布鲁克·鲍德温将解释新技术如何帮助他们。
