MONDAY, Nov. 23, 2020 (HealthDay News) -- If there was an Oscar for "most unhealthy food in a leading role," many of America's most popular movies would be serious contenders.
That's the conclusion of a new review of food content featured in 250 top-grossing U.S. movies. More often than not, the fictional food choices were so bad they wouldn't make the cut of real-world dietary recommendations, the study authors said.
"The overall diet depicted in movies would fail federal guidelines for a healthy diet -- not enough fiber, too much saturated fat and sodium, and … more sugar and three times more alcohol than the average American consumes," said study lead author Bradley Turnwald.
And the implications are big, he said.
"They solidify a norm that unhealthy foods are common and valued in our culture, consumed by famous actresses, role models and even superheroes," said Turnwald, a postdoctoral research fellow in psychology at Stanford University in Stanford, Calif.
He noted that other studies have linked viewing alcohol in movies to earlier binge-drinking among teens. And seeing unhealthy snacks makes kids three times more likely to choose the same snack immediately after the movie, the researchers said.
Advertising and commercial entertainment guidelines for food and alcohol content are more lax in the United States than elsewhere because of First Amendment protections, Turnwald noted.
"Producers can essentially show whatever foods they want, regardless of the audience," he said.
To get a handle on what producers are actually showing, Turnwald's team analyzed the top-grossing U.S. movies released between 1994 and 2018. Domestic box-office numbers were gleaned from the Internet Movie Database.
Two researchers screened each movie in full, noting food and drink content according to categories outlined by the U.S. Department of Agriculture (USDA).
Movie drinks were categorized as alcohol, water, dairy, coffee/tea, sweetened drinks, 100% juice, diet drinks, infant formula and human milk. Foods were sorted into 11 categories: dairy, grains, protein, fruits, vegetables, snack/sweets, mixed dishes, fats/oils, condiments/sauces, sugars, or protein and nutritional powders.
The upshot: 40% of movie beverages were alcoholic, and snacks or sweets accounted for almost one-quarter of the food.
Nearly 94% of movies showed medium or high levels of sugar. Nearly as many (93%) included medium or high levels of fat, and 85% depicted medium or high levels of saturated fat. Medium or high levels of salt (sodium) were found in about half the movies.
The report was published online Nov. 23 in JAMA Internal Medicine.
So the movies fell short of national nutrition guidelines with respect to saturated fat, salt and fiber. And the amount of sugar and alcohol depicted was higher, overall, than real-life Americans actually consume, the investigators found.
"These findings present an opportunity for movie producers to be more mindful of the types of foods and beverages that they depict in movies," Turnwald said. "It's about knowing that what is on-screen has the potential to influence tens of millions of viewers, particularly children, and making more of an effort to depict healthier options as the status quo."
That thought was seconded by Samantha Heller, a registered dietician and senior clinical nutritionist at NYU Langone Health in New York City.
The danger, Heller said, is that "the public feels that if someone is successful, and they copy that behavior, they magically become more like the celebrity they admire. Of course, this is not true and celebrities are not health professionals."
Heller acknowledged that food choices in movies are influenced by the story and dictated by a complex calculation based on character, culture, location and era. Still, "influencers should try to be role models for healthy behavior," she said.
"As parents, caregivers, educators, we can adopt healthy dietary patterns and make sure our families understand the importance of healthy eating," Heller added. "This way when unhealthy behaviors are depicted in movies, they can be viewed as part of the story and not behavior we should imitate."
There's more about healthy eating at the USDA.
