(CNN) — At least 111 substances of unknown safety have been added to foods, drinks and supplements sold in the United States without alerting the US Food and Drug Administration, a new investigation found.
“Food companies are deciding on their own to secretly add unreviewed chemical ingredients to products instead of following existing federal guidelines meant to assure food is ‘generally recognized as safe,’ or GRAS,” said Melanie Benesh, vice president for government affairs for the Environmental Working Group, a health and environmental health advocacy organization that conducted the investigation published Tuesday.
To meet the GRAS standard, companies must demonstrate a new food ingredient is safe by providing widely accepted scientific evidence that’s publicly available. Notifying the FDA of that safety data is customary and ensures regulatory compliance. It’s also voluntary — which means manufacturers can legally self-determine their products to be safe.
“Manufacturers now routinely exploit this GRAS loophole — it’s fast becoming more ‘generally recognized as secret’ instead of ‘generally recognized as safe,’” Benesh said.
The EWG investigation found 49 of the chemicals added by industry in approximately 4,000 products listed in the US Department of Agriculture’s FoodData Central database, which provides public access to nutrient and ingredient information.
“Because the government has never reviewed these chemicals, consumers have no way of knowing if they are safe or carry unknown health risks,” Benesh said.
Even though the GRAS loophole is legal in the United States, it’s difficult to justify from a “scientific and ethical standpoint,” said Mathilde Touvier, director of research at France’s National Institute of Health and Medical Research in Paris, who studies the health harms of additives in ultraprocessed foods.
“It is highly problematic that companies are allowed to self-determine that their own ingredients are ‘GRAS,’ given the obvious financial conflict of interest,” said Touvier, who was not involved in the EWG investigation. “Decisions about the safety of food chemicals should be based on independent assessment by public health authorities.”
CNN reached out to the American Beverage Association and the Consumer Brands Association, who both represent food and drink manufacturers. The ABA did not send a response before publication.
Sarah Gallo, senior vice president of the Consumer Brands Association, said CBA was part of a coalition, Americans for Ingredient Transparency, which is advocating for “federal legislation establishing national uniformity for ingredient safety and disclosure.”
“We support GRAS reform being a part of that bill,” Gallo said, adding that the US has one of the “safest and most highly regulated food systems in the world.”
Adding extracts from ‘natural’ foods
Of the 49 chemicals found in foods, 22 were extracts, according to the investigation. Many appear natural and harmless: aloe vera, cinnamon, cocoa, cranberry seed oil, grape skins, green coffee beans, hemp, lemon balm and mushrooms, to name a few.
“When you start taking substances from grape skin, aloe vera and mushrooms, for example, you may have a concentrated extract or cocktail of substances that come out of it,” said biochemist Maricel Maffini, a former research assistant professor at Tufts University School of Medicine in Boston who coauthored
