NEW YORK — Pizza bagels, chewing gum and bottled water want to play a starring new role in our diets: Foods that can be called “healthy.”
The US Food and Drug Administration (FDA) is revamping its definition of “healthy” to reflect our changing understanding of nutrition science.
The push is fueling debate about eating habits and what the new standard should say.
Frozen food-makers are seeking special rules for “mini meals,” citing little pizza bagels and dumplings as examples that might qualify.
Chewing gum and bottled water companies say they should no longer be shut out from using the term just because their products don’t provide nutrients.
Advocacy groups and health professionals are also weighing in, raising concerns about ingredients like sugar.
Some say the word “healthy” is inherently misleading when applied to a single product instead of an overall diet.
‘Healthy is relative’
“The problem is that healthy is relative,” said Bruce Y. Lee, a professor of international health at Johns Hopkins.
Subsisting on broccoli alone, for instance, wouldn’t be healthy.
The federal standards for use of the word “healthy” on labels were established in 1994 and set limits on total fat and cholesterol.
Susan Mayne, who heads the FDA’s food labeling division, said the definition reflected decades-old understanding of nutrition and needed to be updated.
With the revamp, she said, people will be able to trust that the word “healthy” is based in science, unlike many other terms on packages.
“This is one that the federal agencies will stand behind,” Mayne said.
The government’s dusty definition of “healthy” came under scrutiny in late 2015, when the FDA warned Kind that its snack bars had too much fat to use the term.
Kind pushed back, saying the fat came from nuts.
Since the rule was established more than two decades ago, nutrition experts have drawn a greater distinction between “good fats” like those found in nuts and “bad fats” like the trans fats in oils that are partially hydrogenated, an industrial process that gives foods a longer shelf life.
The link between dietary cholesterol and heart disease is also no longer clear.
Concern over sugar
Separate US dietary guidelines, which are updated every five years, no longer set limits on total fat or cholesterol. They still recommend avoiding trans fats and limiting saturated fats, such as those found in meat and milk.
But even the link between saturated fats and heart disease is now questioned.
Now sugar has become more of a concern, with some health experts saying our past fear of fat led to people gobbling up low-fat products high in sugar.
The shifting views reflect the pitfalls of nutrition science.
Most food studies are based on links between what people say they eat and their health, which leaves the door open for flawed conclusions.
Pinning down cause-and-effect relationships is harder.
It’s why the effort to redefine “healthy” invites such debate. After launching the push in late 2016, the FDA received more than 1,140 public comments on the matter.
The next step is for the FDA to propose a new definition, which would be subject to another round of public comment.
The agency won’t say when it expects to establish a final rule with the new definition.
Like momma used to make
“Healthy” was once just another generic marketing term, like “wholesome” or “like momma used to make,” said Xaq Frohlich, a professor of food history at Auburn University.
After a proliferation of products making claims about health and disease, the FDA set ground rules for the word.
“The reason why ‘healthy’ is getting attention is because a broad part of the American public really wants their food to be healthy,” Frohlich said.
But beyond the regulatory definition, what people consider healthy varies.
Among the notable dietary tribes today: Adherents of paleo, gluten-free, organic and vegan diets. Some of their views are reflected in comments to the FDA last year.
The Sierra Club wants “healthy” to exclude foods made with genetically engineered and artificial ingredients.
The National Pasta Association wants the option to call gluten-free pasta healthy. Right now, it says some gluten-free pastas fall shy of nutrient requirements.
Presence of vitamins
In addition to limiting fat and cholesterol, the current standard requires the presence of a nutrient like calcium, fiber, iron or vitamin C.
It’s partly why bottled water and sugar-free gum companies say they’re unfairly excluded from using the term.
Richard Mann, a lawyer for the International Chewing Gum Association, said sugar-free gum didn’t have any of the nutrients people were supposed to limit.
“It doesn’t have fat. It doesn’t have sugar. It has virtually no calories,” Mann said.
Some question whether an updated definition will make a difference.
The American Academy of Pediatrics says companies will likely just reformulate snacks to meet the new rules.
Companies may have added incentive to do so: The FDA is also considering a symbol that would make it easier for people to identify products that meet the new definition.
