Authors of the wide-reaching study, from the universities of Navarra and Las Palmas, followed and analyzed the diet and lifestyle of over l2,000 volunteers over six years. When the study began, none of the participants had been diagnosed with depression; by the end, 657 of them were new sufferers.
“Participants with an increased consumption of trans-fats presented up to a 48 percent increase in the risk of depression when they were compared to participants who did not consume these fats,” the head study author said. “The more trans-fats were consumed, the greater harmful effect they produced in the volunteers.”
The research team found, at the same time, that after assessing the effect of polyunsaturated fats made up of larger amounts of fish and vegetable oils and olive oil, these products are associated with a lower risk of suffering depression.
The report, published in the online journal PLOS ONE, noted the research was performed on a European population that enjoys a relatively low intake of trans-fats—making up only 0.4 percent of the total energy taken in by the volunteers. “Despite this, we observed an increase in the risk of suffering depression of nearly 50 percent,” said researcher Miguel Martinez. “On this basis we think it of great importance to take this effect into account in countries like the United States, where the percentage of energy derived from these fats is around 2.5 percent.”
The report pointed out that the current number of depression sufferers in the world is around l50 million people, and has increased in recent years. This rise is attributable, according to the authors, “to great changes in the sources of fats consumed in Western diets, where we have replaced certain types of beneficial fats in nuts, vegetable oils and fish with the saturated and trans-fats found in meats, butter and other products such as mass-produced cakes and fast food.”

Some doctors now think that the internal(内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body’s communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.

Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma（哮喘）, Jane Bums at the Harvard School of Public Health found.
Based on these findings．Bums said that current recommended dose（一剂）of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs．Teens who eat less fruit and don"t take in enough fatty acids （脂肪酸） are more likely to have asthma and the signs of breathing difficulty．
Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers．Fatty acids are also found in some nuts as well as some green vegetables"．Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm（痰）．
More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks．"I wouldn"t approve of drinking them, but at least they"re getting their vitamin C from somewhere," Burns said．
Burns added that there are several different ways to get the necessary nutrients．"I think vitamin supplements are fine．I think adding vitamin D to orange juice is fine．But I do think there are added benefits that we don"t fully understand of eating whole foods like fruits and vegetables and fish," she said．The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings．

A standing desk sits high off the floor so a worker can either stand at it or sit on a high stool to use it. Officials at Palo Alto-based Facebook say a number of employees asked about standing desks after news articles were published about the health risks of sitting all day.
The stories cited medical studies that tied excessive sitting to increased obesity and other health problems because of factors including a drop in physical activity. A 2010 study by the American Cancer Society found that women who sat more than six hours a day were 37% more likely to die prematurely than women who sat for less than three hours, while the early-death rate for men was 18% higher. The American College of Cardiology released a study in January that found increased mortality (死亡率) among people who sat longer at home than those who didn"t.
No one seems to compile statistics on the standing-desk trend. But anecdotal reports suggest Silicon Valley is embracing the movement.
Facebook officials say they have seen an upsurge in requests for standing desks to five to eight a week with a total of between 200 and 250 deployed (配置) at the company of more than 2,000 employees. Facebook also is trying out a treadmill station ─ where a worker can walk or run on a treadmill while tapping at a computer.
Google spokesman Jordan Newman said that "many employees at Google opt for standing desks, and we offer them as part of our wellness program" though he said he didn"t know the exact number.
Greg Hoy, 39 years old, asked for a standing desk shortly after joining Facebook seven months ago as a design recruiter. "I don"t get the 3 o"clock slump anymore," he said. "I feel active all day long."
小题1:The underlined word “motivated” in paragraph 1 can be replaced by .
| A．frightened | B．inspired | C．missed | D．discouraged |
| A．a drop in physical activity was the only reason why excessive sitting caused increased obesity. |
| B．women who sat longer were more likely to die prematurely according to a 2010 study by American College of Cardiology |
| C．according to the study, the early-death rate for men was 18% higher than that for women. |
| D．the mortality among people who didn’t sat long at home was lower than that among people who did. |
| A．is a computer that a worker can take along when he walks or runs |
| B．has been tried out by Facebook and now is very popular with other companies |
| C．is a place where workers can exercise while working. |
| D．is a treadmill on which workers can run or walk only after work |
| A．sitting for too long leads to increased health risks |
| B．standing desks have replaced sit-down ones in Facebook Inc. |
| C．more and more workers choose standing desks instead of sit-down ones |
| D．many employees at Google opt for standing desks |
But experts are now warning that the latest shoes in different styles will be causing teenagers discomfort(不舒适） in the short term and storing up years of foot, knee and back pain in the future.
Here, the experts discover the problems caused by teenagers" shoe choice.
KEDS/VANS
Slip-on shoes with elastic (弹性的) sides are particularly popular among teenage boys - with Keds and Vans the most sought-after brands.
The main problem is that they are just too flat—so flat that the heel, which hits the ground first, also becomes damaged and painful.
BALLET PUMPS
The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems.
“As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing a difficult gait（步法）, this leads to short- and long-term problems such as calluses（茧子）, heel and knee pain.”
WEDGES AND STILETTOS
These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer"s body weight forward, making them very shaky.
Teens who wear these shoes regularly are also in danger of joining those millions of women with continuous back pain.
SCHOOL SHOES
So what do podiatrists（足科医生）have on their wish list, especially for everyday wear?
Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark"s, Marks & Spencer or Rhino.
If your teen insists on wearing "bad" shoes, get them some simple foot orthotics(矫形器) in the shoes. These support and correct the movement of the foot and, properly fitted by a podiatrist, can often change their walk and halt the damage.
小题1:Of all the shoes mentioned(提到) in the passage, which can cause the worst problems?
| A．Marks & Spencer. | B．Wedges & Stilettos. |
| C．Keds and Vans. | D．Ballet Pumps. |
| A． | B． | C． | D． |
| A．increase | B．worsen | C．stop | D．cause |
| A．Sports. | B．Science. | C．Health. | D．Shopping. |
