USDA research shows improvements in diet quality between 2005 and 2010
American adults are eating better, making better use of available nutrition information, and consuming fewer calories coming from fat and saturated fat, consuming less cholesterol and eating more fiber, according to a new report from the U.S. Department of Agriculture's Economic Research Service; Changes in Eating Patterns and Diet Quality Among Working-Age Adults, 2005-2010.
The study underscores the importance of robust efforts undertaken since 2009 to improve food choices and diet quality and ensure that all Americans have access to healthy food and science-based nutrition education and advice.
The researchers found that use of nutrition information, including the Nutrition Facts Panel found on most food packages, increased in recent years. Forty-two percent of working age adults and 57 percent of older adults reported using the Nutrition Facts Panel most or all of the time when making food choices. When asked about nutrition information in restaurants, 76 percent of working-age adults reported that they would use the information if it were available.
Reduced consumption of food away from home (such as food from restaurants and fast food) accounted for 20 percent of the improvements in diet quality. A recent study found that during the recession of 2007-2009, U.S. household overall food expenditures declined approximately 5 percent, mostly due to a 12.9 percent decline in spending on food away from home. Calories consumed through food away from home dropped by 127 calories per day, and the average person ate three fewer meals and 1.5 fewer snacks per month away from home. Eating at home more often was also associated with more frequent family meals.
The report also indicates changing attitudes toward food and nutrition. Compared with 2007, the percentage of working-age adults who believed they have the ability to change their body weight increased by three percentage points in 2010. During the same time period, the report shows there was little change in the importance that price played when making choices at the grocery store, but working-age adults placed increased importance on nutrition when choosing items to purchase.
The researcher used individual dietary intake data for working-age adults from the National Health and Nutrition Examination Survey (NHANES), which collects detailed individual and household information on a wide range of health-related topics through questionnaires, physical exams and lab work, in two-year segments. The survey is designed to be nationally representative, with a sample composed of 9,839 individuals. Overall, daily caloric intake declined by 78 calories per day between 2005 and 2010. There were overall declines in calories from total fat (3.3 percent), saturated fat (5.9 percent), and intake of cholesterol (7.9 percent). Overall fiber intake increased by 1.2 grams per day (7.5 percent).
