Chain restaurants aren't getting any healthier despite claims to the contrary, a new study shows.
The
overall calorie and sodium levels in the main entrees in top U.S. chain
restaurants did not change from 2010 to 2011, the study published in
the Journal of the Academy of Nutrition and Diabetes on Oct. 1 revealed.
"Across
the restaurant industry, we see a pattern of one step forward, one step
back," co-author Helen Wu, a policy and research analyst at the
Institute for Population Health Improvement at UC Davis Health System,
said in a press release.
"Restaurants make changes to their menus regularly, but they may make
both healthy and unhealthy changes simultaneously. This study provides
objective evidence that overall, we did not see a new wave of healthier
entrees come in to replace less healthy ones."
The new study looked at more than 26,000 regular menu entrees
that were served in 213 major U.S. chain restaurants in 2010 and 2011,
the year after some establishments began implementing menu labeling.
Some of the restaurants had children's menus as well.
The
average entree in 2010 contained 670 calories. That calorie count went
unchanged in 2011. Sodium levels went from 1,515 milligrams per menu
item to 1,500 milligrams in the same time frame.
The American Heart Association recommends people cap their daily sodium intake at 1,500 milligrams, about 500 lower than government recommendations.
Items
served at family-style restaurants in the top 75th percentile of sodium
content were 70 milligrams lower on average by 2011 than the previous
year. However, these items still had too much sodium for anyone who was
paying attention to their sodium intake, according to the authors.
There were not many calorie differences even among entrees that were added or reformulated between the study period.
Fast
food entrees were on average 40 calories lower, but children's fast
food entrees did not see much changes in calorie and sodium levels.
"Consumers
need to be aware that when they step into a restaurant, they are
playing a high-stakes game with their health by making dietary choices
from menus that are loaded with high-calorie, high-sodium options," Wu
said. "This is a game that health-conscious consumers have a very low
chance of winning, given the set of menu offerings available in U.S.
chain restaurants today."
The researchers called for more
longer-term studies after the menu labeling requirement is mandated.
They also wanted people to think of more ways to help promote nutrition
at restaurants.
Joy Dubost, the National Restaurant Assn.'s director of nutrition, told the Los Angeles Times
that there were problems with the study's methodology, and a year is
too short to track changes. She recognized though that companies have to
work to lower calories and sodium.
"Some of these commitments
have to take time to ensure you are bringing the consumer along," she
said. "Ultimately, they're the ones who will dictate what's on the
menu."
The Center for Science in the Public Interest added in a 2013 report that 91 percent of kids' meals at 34 top chains do not meet a single standard set by the National Restaurant Association's voluntary Kids LiveWell program.
