Analyzing data collected over decades from about 340,000 people around the world,
几十年间，人们对全球34万人进行了数据采集，通过对数据的分析，
researchers in Britain found that those who met all five requirements
英国研究人员发现满足这五项要求的人
were 32% less likely to develop lung, breast or colon cancer, the most common cancers.
患肺癌，乳腺癌或结肠癌的几率降低32%，这三种是最常见的癌症。
Looking at things like obesity,
就拿肥胖来说，
It's you may see different results, slightly different results in different studies.
你会看到不同的结果，不同的研究结果会稍有差别。
But when you add them all together into one set of analyses, it really helps give you a full picture of what's going on.
但当你把它们都集中到一起分析时，你就可以有一个了解。
Dr. Anne McTiernan, the researcher at Fred Hutchinson Cancer Research Center in Seattle,
西雅图佛瑞德·哈钦森癌症研究中心的研究员安妮·麦克蒂安博士说，
says the increased availability of food with high content of fat, sugar and salt is contributing to rising rates of diabetes and obesity.
高脂肪，高糖和高盐食物的增加导致了糖尿病和肥胖率的增加。

Most people know they should avoid fast food, yet because it is so available, many have trouble changing their diet.
大多数人都知道他们不应该吃快餐，但因为它们太常见了，许多人很难改变饮食习惯。
But Dr. McTiernan says people should not wait for the government or industry to make their food choices.
但麦克蒂安博士说，人们不应该等待政府或行业为他们的食物做出选择。
I would say get educated, figure out if you are gaining weight over time, figure out if you have the high risk of cancer.
我想说你要去了解，清楚自己的体重是不是在一直增长，清楚自己是不是有很高的患癌风险。
And then take steps yourself and things that you can do for yourself in your family.
然后采取措施，看自己可以在家里做点什么。
Scientists in the US are working on a simple blood test that could detect several types of cancer much earlier than before,
美国科学家们正在研发一种简单的血液检测，它可以提早检测出几种类型的癌症，
raising the chance of stopping its development.
增加了阻止癌症进一步发展的可能性。
For some people, an early indication of cancer can be a teachable moment, a time when they're more aware that they're at risk,
对于许多人而言，早期癌症检测是一种了解，让他们意识到自己处在危险之中，
and that they could be making changes, and perhaps don't want to make changes.
他们可能会做出改变，也或许他们就不想改。
Dr. McTiernan says her own research shows that getting someone who is overweight or obese to lose weight,
麦克蒂安博士说她的研究表明，让超重或肥胖者减肥，
or someone who is inactive to become active can really reduce the risk of cancer.
或是让不爱运动的人运动起来，这些可以降低患癌风险。
