Buy your groceries online? Watch out for this food labeling gap
Online grocery shopping has soared in popularity, but new Friedman School of Nutrition Science and Policy research shows food information—like nutrition facts, ingredients, or allergens—isn’t always accessible to consumers
Picture this: You’re shopping online for this week’s groceries. You try to pick healthy options based on the information provided by the online retailer. You can tell that the products you’re choosing are organic, non-GMO, or Fair Trade Certified. But in many cases, you can’t find the nutrition facts, ingredient list, or even a list of allergens.
A new, comprehensive study of online grocery retailers shows this problem is pervasive, to the detriment of public health and safety in the U.S. The study, led by researchers at the Friedman School of Nutrition Science and Policy at Tufts University and published in Public Health Nutrition on Oct. 17, shows a lack of present, accessible, and legible information about the food consumers buy, while marketing claims are still prominent. The absence of accessible food labeling has tangible consequences for public health, said Julia Sharib, first author on the study and manager of research and communications for the Food is Medicine Institute at the Friedman School.
“The government has clearly intended that you should be able to know certain things about your food,” said Sean Cash, Bergstrom Foundation Professor in Global Nutrition at the Friedman School and senior author on the study. “The way we’ve regulated that in the United States is to put that information on the packaging. But that hasn’t carried over to online spaces very well.”
A Lack of Information
Cash and researchers at the Friedman School and New York University (NYU) first identified the lack of accessible food labeling among online retailers in a 2022 pilot study of 10 food products across nine online grocery retailers. That study found that information required by the Food and Drug Administration (FDA) about food, such as nutrition facts, an ingredient list, and an allergen list were often absent, and were less present than marketing claims.
The lack of information accessible in online settings reveals a “major gap” in federal regulations, Cash said. While food manufacturers are required by the FDA to present certain information on food packaging, online grocery retailers aren’t required to reproduce that information on their websites. That means that consumers won’t necessarily be able to access information about calories, nutrition content, or allergens when buying their groceries online.
Since 2022, there were some reasons to think that retailers would step up their game. First, online grocery shopping is here to stay—recent data from the U.S. Department of Agriculture (USDA) indicates that 20% of Americans buy their groceries online, while over 80% have done so in the past three years. The trend has been aided by a drop in online food prices relative to in-store shopping: Prices are now roughly comparable between in-store and online groceries, which hasn’t always been the case.
Second, online food retailers could have responded to the growing market by deciding to get out ahead of any regulatory action. “We thought there might be practical changes in what food retailers are doing,” Cash said.
There have been signs that the FDA is considering regulatory action, too. In 2023, the agency issued a request for information on food labeling in online grocery shopping, citing previous research from Cash and his colleagues as one basis of their request. “We, and others, have been pushing for change,” Cash said. But the agency has not yet taken regulatory action to close the gap.
The new study, with co-authors Jennifer Pomeranz, associate professor of public health policy and management at the NYU School of Global Public Health, and Dariush Mozaffarian, director of the Food is Medicine Institute and Jean Mayer Professor of Nutrition at the Friedman School, gives a more complete look at the issue and analyzes 60 food products across 10 different online grocery retailers. The food products were chosen to represent the typical range of food commonly sold at supermarkets, based on a formula used by the USDA for administering food assistance programs. The results show the trend has persisted: Each FDA-required label was present, accessible, and legible for just 35.1% of products.
Marketing claims and labels, though, were present for 83.7% of products. That’s what Cash finds unpalatable. “It’s far easier to find marketing that’s trying to sell you the food rather than the information that our society agrees should be there to tell you about your food,” he said.
“We saw many cases in which a nutrition facts label, for example, was only accessible after scrolling through a dozen marketing images, essentially forcing any consumers seeking that label to interact with marketing language,” Sharib said.
Making Shopping More Accessible
Studies show that population health is better when ingredient lists and nutrition facts are provided. When consumers can’t access that information, retailers “run the risk of perpetuating consumer’s incorrect understandings about the healthfulness of the foods they buy,” Sharib said.
Additionally, plenty of Americans follow specific diets meant to control certain health conditions and may be looking for foods with a specific nutrition content. “For example, if you’re worried about sodium intake because you have hypertension, food labeling is something that can be a very important part of your life,” Cash said. For people with specific allergies, a lack of food labeling can be dangerous, too.
The best way consumers can get the FDA-required information is to visit the websites of the food manufacturers themselves, Cash said. On those sites, nutrition information and ingredient lists are much more likely to be present and legible. Cash cautions that food labeling found in product reviews can be helpful, but may also be out of date or inaccurate.
And ultimately, the onus should be on regulators and the industry to provide important information to consumers, Cash said. “Putting the burden on consumers is not what we should be doing,” he said.
There are a few solutions: First, regulators or congress could pass new laws or issue new regulations to compel food retailers to make food labeling accessible. Second, the U.S. government could help online retailers to make food labeling accessible by providing a public database of nutrition, ingredient, and allergen information of packaged foods, Cash said.
“We simply cannot continue to let this sector grow without modern regulation,” Sharib said.
