Sugar shocked. That describes the reaction of many Americans this week following revelations that, 50 years ago, the sugar industry paid Harvard scientists for research that shifted the focus away from sugar’s role in heart disease—and put the spotlight (注意的中心) squarely on dietary fat.

        What might surprise consumers is just how many present-day nutrition studies are still funded by the food industry. Nutrition scholar Marion Nestle of New York University spent a year informally tracking industry-funded studies on food. “Roughly 90% of nearly 170 studies favored the sponsor’s interest,” Nestle tells us. Other systematic reviews support her conclusions.

        For instance, studies funded by Welch Foods—the brand behind Welch’s 100% Grape Juice—found that drinking Concord grape juice daily may boost brain function. Another, funded by Quaker Oats, concluded, as a Daily Mail story put it, that “hot oatmeal (燕麦粥) breakfast keeps you full for longer.”

        Last year, The New York Times revealed how Coca-Cola was funding well-known scientists and organizations promoting a message that, in the battle against weight gain, people should pay more attention to exercise and less to what they eat and drink. Coca-Cola also released data detailing its funding of several medical institutions and associations between 2010 and 2015.

        “It’s certainly a problem that so much research in nutrition and health is funded by industry,” says Bonnie Liebman, director of nutrition at the Center for Science in the Public Interest. “When the food industry pays for research, it often gets what it pays for.” And what it pays for is often a pro-industry finding.

        Given this environment, consumers should be skeptical (怀疑的) when reading the latest finding in nutrition science and ignore the latest study that pops up on your news feed. “Rely on health experts who’ve reviewed all the evidence,” Liebman says, pointing to the official government Dietary Guidelines, which are based on reviews of hundreds of studies.

        “And that expert advice remains pretty simple,” says Nestle. “We know what healthy diets are—lots of vegetables, not too much junk food, balanced calories. Everything else is really difficult to do experimentally.”

解析：A。根据题干中的Coca-Cola-funded studies可定位至原文第四段。该段第一句提到，可口可乐资助科学家和组织来宣扬人们在减肥时更应该注重锻炼而不是饮食的观点。A项是对此内容的概括总结，exercise为原词复现，diet是对what they eat and drink的同义替换，故A项为正确答案。

错项排除：B项利用原文中出现的what they eat and drink和weight gain设置干扰，但可口可乐资助研究是为了让减肥人士重锻炼而轻饮食，B项与原文内容相悖，故错误。文中并没有明确提到喝可口可乐不会增重，故C项错误。原文中并没有提到食品行业在对抗肥胖方面的作用，D项在文中无依据，故排除。
