Food and nutrition researchers have long pointed out similarities between ultra-processed food and tobacco, said Christina Roberto, a health policy researcher at the University of Pennsylvania and co-author of the article arguing for regulating these foods like tobacco.
“Many of us have looked at the successes that tobacco control has achieved in an aspirational kind of way, like, well, maybe we could do something similar with food. But we felt like now was a good time to write the article we wrote because there’s so much conversation and attention focusing on ultra-processed foods right now,” she said.
In a statement, the Consumer Brands Association, which represents food companies, said that scientists do not agree on what is an ultra-processed food, and that the U.S. has “one of the safest and most highly regulated food systems in the world.”
Moran said there is a common framework that scientists use to identify different types of food: whole foods like fruit and vegetables, processed ingredients used for cooking like butter and salt, food that is processed for safety and preservation like cheese and canned food, and ultra-processed food like chips, soda and candy.
Policy ideas that change the food environment, such as limiting where stores can display ultra-processed foods, could also make a difference, said David Sarwer, a longtime obesity researcher and director of the Center for Obesity Research and Education at Temple University.
“From my perspective as a behaviorist, I think the idea of the placement of foods is really, really important,” he said. “This has been an issue that we’ve talked about in obesity interventions for a long, long time and I do think that stronger legislation around where foods can be placed, so we minimize that exposure, could actually be very, very helpful, not only I think for adults, but also for children.”
He added that other countries have more robust food policies to address obesity. The U.K. recently banned advertising for unhealthy foods online and on TV before 9 p.m. The U.K., France, Finland and Norway also all tax companies that sell sugary drinks.
On the other hand, Sarwer said there are still questions about how effective such policies are. He pointed out Philadelphia has had a soda tax for almost a decade now, but “we haven’t necessarily seen a robust body of evidence that said that it’s led to the improvement of the health and well-being of Philadelphians.”
“It may be unrealistic to think that in only 10 years, we would see an impact downstream on the health and well-being of people who live in Philadelphia. I hope … we get to that point where we see that evidence, but we’re not there quite yet,” he said.
