[ti:More Americans on Special Diets for Health Reasons] [by:www.houshang36.top] [00:00.00]更多听力请访问51VOA.COM [00:00.04]More Americans say they are on a special diet [00:04.88]compared with Americans about 10 years ago. [00:09.48]That information comes from a report released this week [00:14.56]by the U.S. Centers for Disease Control and Prevention, or CDC. [00:21.92]The increased dieting comes at a time when obesity levels continue to rise. [00:29.76]The CDC report found that 17 percent of Americans [00:35.48]said they were on diets in 2017-2018 [00:40.76]— up from 14 percent about 10 years earlier. [00:45.76]Over the same period, obesity levels increased [00:50.72]in the U.S. to 42 percent — up from 34 percent. [00:56.96]Dana Hunnes is a professor of public health and nutrition [01:02.28]at the University of California, Los Angeles. [01:06.52]Hunnes said that the number of Americans [01:09.84]who said that they are on a diet is lower than expected. [01:15.04]This is because diet-related diseases are very common in the country. [01:21.52]The report noted that about half of American adults [01:25.56]have diet-related health problems, such as diabetes and heart disease. [01:32.00]Overall, more women reported being on a diet than men. [01:37.56]The heavier and more educated people were, [01:41.08]the more likely they were to report being on a special diet, the study found. [01:47.52]Between 2007 and 2008, and 2017 and 2018, [01:56.00]diets described as "weight loss or low calorie" grew in popularity. [02:02.64]Low-carbohydrate diets became more popular, [02:06.72]while low-fat and low-cholesterol diets became less popular. [02:12.92]The findings were part of an ongoing national survey. [02:17.52]People who took part in the survey were asked the following question: [02:23.08]"Are you currently on any kind of diet, [02:26.60]either to lose weight or for some other health-related reason?" [02:31.92]Becky Ramsing is a dietician and program officer [02:36.76]at Johns Hopkins Center for a Livable Future. [02:40.80]Ramsing said that people make very different kinds of choices [02:46.08]in the hopes of losing weight. [02:48.40]In some cases, she said people might not understand [02:53.88]why the choices they make do not help them lose weight. [02:58.72]"They won't eat bread, but then they'll go eat a lot of other things [03:04.20]that are higher in calories," she said. [03:07.76]Ramsing added that many American diet trends ban some foods. [03:13.88]But to make lasting changes, [03:16.64]she said people should consider their eating overall. [03:20.92]That will help them deal with another problem of diets, she noted. [03:26.28]Diets are hard to continue doing over time. [03:30.52]I'm John Russell. [03:32.60]更多听力请访问51VOA.COM www9778con
