them lose weight or at least keep them from gaining it.Yet it seems to have exactly the opposite effect,
according to a new study.
Researchers from the University of Texas said those who drank two or more diet sodas a day had
waist size increases that were six times greater than those who didn"t drink diet soda."What we saw was
that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.
The study was based on data from 474 participants in a large, ongoing research project, where the
participants were followed for nearly l0 years.
While the findings are surprising, they also offer some explanations.
Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that
when patients are switched from regular to diet soda, they don"t lose weight at all."We weren"t seeing
weight loss necessarily, and that was confusing to us," said Rogers.
So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people
think they can eat more if they drink diet soda, and so over-compensate for the missing calories.
A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice."Data from
this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be
risky," said Helen P.Hazuda, professor at the University of Texas"s school of medicine."They may be free
of calories, but not of consequences."

Most people know this joke. But recently, some people have been much more worried about how
the grizzly bear and mountain lion can cross the road.
"Millions of animals die each year on U.S. roads," the Federal Highway Administration reports. In
fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
"Eco-passages" may help animals cross the road without being hit by cars. They are paths both over
and under roads. "These eco-passages can be extremely useful, so that wildlife can avoid road accidents," said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona
University found foot marks left by mountain lions on an eco-passage that went under a highway. This
showed that the lions used the passage.
Builders of eco-passages try to make them look like a natural part of an area by planting trees on and
around them. Animals seem to be catching on. Animals like salamanders (火蜥蜴) and grizzly bears are
using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might
see an animal overpass!
B. the driving condition has improved greatly
C. the measure for protecting wildlife fails to work
D. an increasing number of animals are killed in road accidents
B. a fence built for the safety of the area
C. a bridge for animals to get over a river
D. a path for animals to cross the road
B. animals begin to learn to use eco-passages
C. animals are crossing the road in groups
D. animals are increasing in number
B. wild animals may jam the road
C. they may see wild animals in the park
D. they may see wild animals on eco-passages
B. Endangered animals increase because of roadkill
C. Animals fail to cross the road
D. Take steps to protect animals in danger
sitting for prolonged periods - even if you also exercise regularly - could be 1 for your health. And it
doesn"t matter where the sitting takes place - at the office, at school, in the car or before a computer or
TV - just the overall number of hours it 2 .
Research is preliminary, but several studies 3 people who spend most of their days sitting are more
likely to be fat, have a heart attack or even die.
In an editorial 4 this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish
School of Sport and Health Sciences suggested that authorities rethink how they define 5 activity to
highlight the dangers of sitting.
While health officials have issued guidelines 6 minimum amounts of physical activity, they haven"t
suggested people try to limit how much time they spend in a seated 7 .
"After four hours of sitting, the body starts to send 8 signals," Ekblom-Bak said. She explained that
genes regulating the amount of glucose and fat in the 9 start to shut down.
Even for people who 10 , spending long stretches of time sitting at a desk is still harmful. Tim
Armstrong, a physical activity expert at the World Health Organization, said people who exercise every
day - 11 still spend a lot of time sitting - might get more benefit if that exercise were spread across the
day, 12 in a single bout.
That wasn"t 13 news for Aytekin Can, 31, who works at a London financial company, and spends
most of his days sitting 14 a computer. Several evenings a week, Can also teaches jiu jitsu, a Japanese
martial art 15 wrestling, and also does Thai boxing.
"I"m sure there are some detrimental 16 of staying still for too long, but I hope that being 17 when
I can helps," he said. "I wouldn"t want to think the sitting could be _18 dangerous."
Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years,
researchers found people who sat 19 had a higher death risk, independently of whether or not they
exercised.
Figures from a US survey in 2003-2004 found Americans spend more than half their time sitting, from
working at their desks to sitting in cars.
Experts said more research is needed to 20 just how much sitting is dangerous, and what might be
possible to offset those effects.

| The Diet Zone: A Dangerous Place Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word "diet" everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically. Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption (消耗)of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word "diet" in food labels(标签). On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don"t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance (抵 抗)and struggle. The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients (营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous. Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them. | |||
