Example Input: Paragraph: Veggies given names like “zesty ginger-turmeric sweet potatoes” and “twisted citrus-glazed carrots” were more popular than those prepared exactly the same way but with plainer, more healthful-sounding labels. Diners more often said “no thanks” when the food had labels like “low-fat,” ″reduced-sodium” or “sugar-free.” More diners chose the fancy-named items, and selected larger portions of them too in the experiment last fall at a Stanford University cafeteria. “While it may seem like a good idea to emphasize the healthiness of vegetables, doing so may actually backfire,” said lead author Bradley Turnwald, a graduate student in psychology. Other research has shown that people tend to think of healthful sounding food as less tasty, so the aim was to make it sound as good as more indulgent, fattening fare. Researchers from Stanford’s psychology department tested the idea as a way to improve eating habits and make a dent in the growing obesity epidemic . “This novel, low-cost intervention could easily be implemented in cafeterias, restaurants, and consumer products to increase selection of healthier options,” they said. The results were published Monday JAMA Internal Medicine. The study was done over 46 days last fall. Lunchtime vegetable offerings were given different labels on different days. For example, on one day diners could choose “dynamite chili and tangy lime-seasoned beets.” On other days the same item was labeled “lighter-choice beets with no added sugar,” ″high antioxidant beets,” or simply “beets.” Almost one-third of the nearly 28,000 diners chose a vegetable offering during the study. The tasty-sounding offering was the most popular, selected by about 220 diners on average on days it was offered, compared with about 175 diners who chose the simple-label vegetable. The healthy-sounding labels were the least popular. Diners also served themselves bigger portions of the tasty-sounding vegetables than of the other choices. Turnwald emphasized that “there was no deception” —  all labels accurately described the vegetables, although diners weren’t told that the different-sounding choices were the exact same item. The results illustrate “the interesting advantage to indulgent labeling,” he said. Dr. Stephen Cook, a University of Rochester childhood obesity researcher, called the study encouraging and said some high school cafeterias have also tried different labels to influence healthy eating. “It shouldn’t be a surprise to us because marketing people have been doing this for years,” Cook said. ___ Follow AP Medical Writer Lindsey Tanner at http://www.twitter.com/LindseyTanner and her work can be found at http://tinyurl.com/kv4uhoh Claim: Sweet sizzlin’ beans!

Example Output: Researchers tried a big serving of food psychology and a dollop of trickery to get diners to eat their vegetables. And it worked.

Example Input: Paragraph: Cost is not a component of this story. That is an issue, as the story compares three weight-loss surgical options for morbidly obese individuals, and readers might well be interested in the economics. Also, it would be useful to discuss the costs of not having surgery in the matched population. The story does a nice job of making the weight loss comparisons—both over time for gastric bypass surgery and across surgical options—clear. The story makes no mention of harms. Bariatric procedures can lead to an array of complications that are worth considering. And on the flip side, it’s worth noting that research also has indicated that bariatric surgery can both extend quantity and quality of life when compared to not having surgery. Details of the two-part study conducted here are included and clearly described. And we were also pleased to see several study limitations discussed: “For example, the study included mostly men, so the findings may not apply to women.” That said, we do wish more had been said about the study participants, such as average body mass index levels before and after the surgeries. Morbid obesity is a major and growing health issue with frustratingly few treatment options. Sources are clearly identified, along with information about their links to the study itself (one scientist was the study’s lead researcher, and the other quoted in the story was independent). This is another strong point of the story. The study compared the longer term weight-loss outcomes of the three primary bariatric surgical procedures. The story doesn’t make it readily clear how accessible these surgeries are, and who is a good candidate for one. Typically, these procedures are for people over a certain body-mass index, for example. And insurance coverage may or may not pay for it. The story is clear that this study contributes to a growing set of data about long-term weight-loss effects of these surgeries. Duke Medicine issued a news release, and the HealthDay story does not rely solely on it. Claim: Weight-Loss Surgery Sheds Pounds Long Term
Example Output: Bariatric surgeries have been identified as perhaps the most successful means for people who are morbidly obese to lose weight, and use of these procedures is increasing, according to the American Society for Metabolic and Bariatric Surgery. Information about whether the weight-loss results last, and for how long, is a useful addition to the growing medical literature on these surgeries. The study described here by HealthDay speaks directly to the issue in a couple of well-designed analyses, and the story does a good job of explaining both the methods and the results. Missing from an otherwise good narrative is information about the risks of these procedures, as well as their costs and overall availability to the general public. Obesity is a major health issue in the United States, and the use of bariatric surgical procedures is being used increasingly for those who are morbidly obese. Knowing how long people keep the weight off–and by how much—is useful for those deciding whether to opt into the procedure. Also of interest is if the health benefits, such as remission of type 2 diabetes, were sustained, though this study didn’t appear to investigate that.

Example Input: Paragraph: Home to the two largest ports in the country in Los Angeles and Long Beach, California has roughly 1.5 million medium and heavy duty trucks on the road that spew harmful pollutants as they haul freight to warehouses. The state’s transportation sector accounts for 41% of all greenhouse gas emissions, a cause of climate change, and is a major source of ozone and particulate matter pollution that can cause respiratory problems. Regulators estimate the new rules would result in roughly 74,000 zero emission trucks on the road in California by 2030, or about 4% of all trucks. California already has a rule requiring car makers to offer for sale specific numbers of clean cars. But Mary Nichols, chairwoman of the California Air Resources Board, said the truck rule would be the first of its kind in the world. The board considered the new rule in a public hearing on Thursday that drew more than 100 public comments. The board won’t vote on the proposal until next year. But Thursday was the last chance for advocates and opponents to weigh-in. “Trucks are increasingly a major contributor to air pollution nationwide, but especially in our cities where they are among the largest sources of toxic emissions in vulnerable neighborhoods,” Nichols said. If adopted, at least 15% of sales of heavy duty pickup trucks like the Ford F-250 and full size vans like the Chevrolet Express must be zero emission vehicles by 2030. That standard also applies to the heaviest trucks, including tractor trailers. The standard is tougher for box trucks and delivery trucks, mandating at least half of all new sales be zero-emission vehicles by 2030. The rules are part of the state’s plan to have 100% zero emission truck sales by 2040. By then, state regulators say the phased-in limits could prevent more than 600 premature deaths due to poor air quality in California. Sales requirements for the heaviest trucks would begin in 2024 and gradually increase until 2030. Sales requirements for pickup trucks would not begin until 2027. The proposed rules continue California’s aggressive push on environmental regulations, which already include tougher emission standards on cars and trucks than the federal government imposes and a first-in-the-nation cap-and-trade system that requires big polluters to purchase credits to let them pollute. Most environmental groups support the rule, but they say it is not strong enough. Trucks last longer than passenger vehicles, which is why companies are slower to replace their fleets. While the rules would impact up to 50% of some new truck sales by 2030, it would only result in about 4% of trucks on the road being zero emission vehicles. Andrea Vidaurre, policy analyst for the Center for Community Action and Environmental Justice, said these types of trucks historically are clustered in poorer communities. That includes communities in the Inland Empire, an area next to Los Angeles where warehouses store freight from ports. The group says low-income communities can be most impacted environmental health hazards. “We have so much traffic going in right now just in this area, and the rule currently, it would barely cover it,” she said. Jed Mandel, president of the Truck and Engine Manufacturers Association, said he supports efforts to get more zero-emission trucks on the road. But he said making rules “on a naked sales mandate is fundamentally flawed.” “Trucks are not cars. Our customers invest capital to purchase vehicles that must return a profit,” Mandel said. “We all know today that (zero emission vehicles) are more expensive than traditionally fueled vehicles.” Mandel said California regulators should narrow the rule to apply to trucking segments that are “more readily suited to that technology,” including school buses and municipal fleet step vans. Claim: California considers requiring zero emission truck sales.
Example Output:
The country’s most populous state could become the first to require a portion of new truck sales be electric or “zero emission” vehicles as California grapples with how to clean up its worst-in-the nation air quality.
