Passage Two
短文二
Most Americans don't eat enough fruits, vegetables or whole grains.
絕大多數美國人都沒有食用足夠多的水果、蔬菜或全谷物。
Research now says adding fiber to the teen diet may help lower the risk of breast cancer.
研究者現在宣稱，在青少年飲食中添加纖維有助于降低患乳腺癌的風險。
Conversations about the benefits of fiber are probably more common in nursing homes than high schools.
有關纖維益處的交談，養老院可能要比高中學校更普遍。
But along comes a new study that could change that.
但一項新研究的出現可能會改變這一狀況。
Kristi King, a diet specialist at Texas Children's Hospital, finds it hard to get teenage patients' attention about healthy eating.
田納西兒童醫院的飲食專家克里斯蒂·金發現，要引起青少年患者對健康飲食的注意很難。
By telling them they are eating lots of high-fiber foods could reduce the risk of breast cancer before middle age.
但通過告訴他們食用大量高纖維的食物能降低中年之前患乳腺癌的風險。
That's a powerful message.
會是一個強有力的信息。
The new finding is based on a study of 44,000 women.
這個新發現是基于一項涉及44,000名婦女的研究。
They were surveyed about their diets during high school and their eating habits were tracked for two decades.
該研究調查了她們高中時期的日常飲食，并跟蹤她們的飲食習慣長達二十年。
It turns out that those who consumed the highest levels of fiber during adolescents had a lower risk of developing breast cancer, compared to women who ate the least fiber.
研究結果顯示，相對于那些青少年時期消耗最少纖維的婦女，那些在該時期消耗了最高水平纖維的人患乳腺癌的風險要更低。
This important study demonstrates that the more fiber you eat during your high school years, the lower your risk is in developing breast cancer in later life.
這項重要的研究表明，你在高中階段食用的纖維越多，日后患乳腺癌的風險就越低。
The finding points to long-standing evidence that fiber may reduce circulating female hormone levels, which could explain the reduced risk.
該研究證實了長期存在的證據，那就是纖維能夠降低雌性激素的循環水平，它能夠解釋該風險降低的原因。
The bottom line here is the more fiber you eat, perhaps, a lower level of hormone in your body, and therefore, a lower lifetime risk of developing breast cancer.
在這里最重要的一點是你食用的纖維越多，那么你身體里的荷爾蒙水平可能就越低，因此一生當中患乳腺癌的風險就越低。
High-fiber diets are also linked to a reduced risk of heart disease and diabetes.
高纖維的飲食還可以降低心臟病和糖尿病的患病風險。
That's why women are told to eat 25 grams of fiber a day—man even more.
這就是為什么女性被告知一天要食用25克的纖維——男性甚至要食用更多。
